My nightmare is still that I'm on an airliner that starts misbehaving, I turn and Mentour is sitting next to me saying "Aaand this is when things start to happen really quickly".
@@InventorZahran Seriously, the "Fifty... fourty... thirty... twenty... ten..." at the start of each video stresses me out. And no, I don't care whether that's supposed to happen during a normal landing.
Even if things get really bad, there will always be several YT commercials before whatever finally happens, happens. Those extra minutes should help the crew sort things out. 🙂
Planes are thunkfully a lot tougher than their technical max limits, another great example was Fedex Flight 705, the plane did upside down fighter jet manouveres while they were fighting in the cockpit.
You could easily think that watching these videos would make you a nervous passenger. But instead it's the opposite. Your calm voice and detailed technical analysis what had actually happened during the flight at least makes me much more confident and relaxed when sitting in plane. Thank you.
On the contrary, the fact that the pilots were so confused and mishandled the aircraft so badly, only increases my anxiety about flying. So much of what the pilots did was completely inappropriate, as if they didn’t know how to fly the plane.
I have to agree this way better then the clickbate "worst ever possible accident" and they scream in your ear about some cessna that got minor damage after it landed too fast.
I'm.... unconvinced. The number of times pilots become baffled by things that should be obvious (to them as experts), and the number of times blocked Pitot tubes have been the source of nasty accidents or incidents and STILL not been checked pre-flight or recognised as the issue during flight scares me rigid. You cannot convince me this won't happen again.
The editing on this video was awesome, I didn't hear anything about this incident before and I cannot believe that this wasn't a disaster accident and everyone survived this terrifying experience
@@MentourPilot Just like AF447, Airbus aircraft for some reason seem to confuse the pilots when switching between normal law/alternate law and direct law. Couple that with stall warnings/overspeed warnings which makes even experienced pilots struggle to figure out what's going on and what steps they need to recover the aircraft. I'm not sure whether more training is needed or an Airbus system change to make it less complicated.
@@Robert_N yeah I can imagine it's damn near impossible to tease out complicated programmed logic such as "if this flight control law changes to that flight control law, so and so will happen meaning such and such control surface will behave in this or that way requiring this particular corrective action" while plummeting towards the ground at 500km/hr. Works great for a computer, but the human brain is not designed to engage in such multi-step logic while in a high stress environment.
I’ve kind of binged a bit on his videos, and while there is a noticeable improvement, these videos are started out excellent (at least as far back as 3 years ago). The improvements have been steady and gradual and I agree with you 100%, this one is on par, if not better than a “network TV” production. We could easily pit this video up with a Discovery Channel, TLC, NBC, CBS or Netflix production and no one would be able to notice anything “inferior”. To me, he started the channel with an already superior level of professionalism & technical abilities and he’s just continued to get better and better. Awesome work! 🤠👍🏼
@@ricktaylor14001 I was just getting ready to say this before I read your reply. The quality increase has been steady rather than in big leaps, but the quality has reached the point that it is as good or in some cases better than the TV documentaries that used to be more common.
With all those mountains in the area, the highly attentive ATC controller is likely a big reason they didn't fly straight into one while being disoriented!
Hi, just FYI to people who werent sure if the passengers were aware of what was going on -- they were. One of the flight attendants was giving an announcement about S7 Priority program when things first started to go wrong, and she stopped mid sentence and didnt continue. The passengers were told to put their seat belts on, and from there on just were sure they were going to die. They said no one panicked, everyone was quiet and going through it internally. One of the passengers said that there wasnt even a point of taking a video either because they were going to crash and the phone's going to burn anyways. Afterwards, the media dubbed it the "scary fun" flight, which doesnt work as well in the direct translation, but can loosely be interpreted as "terribly fun" flight (Source is an interview in Russian) My god that must have been terryfying and as I was watching the video, I had this awful feeling inside that they all died.
There was that one plane crash in India where the guy was recording as they were about to land, only for the plane to crash and the phone somehow survived in the flames and fire. It is totally possible a phone could have survived.. so always film on the plane!
At points I was completely sure this was going to be a crash case. Props to... Airbus for building an aircraft sturdy enough to take this kind of punishment. I guess?
@@bengrogan9710I would be surprised if the aircraft was not a total write off or at least due for some major inspection and overhaul after this incident. Then again I also would not be surprised if the aircraft was just put back into service after this with only a few forms filled out saying maintenance had done the required inspections after doing absolutely nothing. I also would not be surprised if the pilots never received proper training on unreliable airspeed in the first place. I may be wrong though, I don't know as much about the Russian airline industry and whether they have effective processes in place to mitigate the culture of corruption which is so rampant in the rest of the Russian economy and state.
I remember discussing the Air France 447 flight online, and arguing that there should be a standby mode for guessing the airspeed based on throttle and control surface settings, and GPS data. (And being told that I was a stupid head for even suggesting such a thing.) Glad to see Airbus actually developed something along those lines, and it's actually useful when used properly.
@tanmaysingh267 Fighter jets can't really assist a plane in any meaningful way. Near an airport, they would be redundant, as ATC radar can be used to give height, speed, and direction - and is already on station. Half way across the Pacific or Atlantic, there often isn't any fighter jets in range, and by the time the crew realise the problem, they're often less than a minute from death. And no fighter could reach them in time, even if they did have the range.
@tanmaysingh267 Secondary radar is used extensively, for a variety of purposes, but primary radar is definately still in use. And 3d primary ATC radar is a decades old technology by now. They might have to flip a switch to get the 3D data, but it's still there if they needed it.
GPS data is only for altitude and it cannot measure airspeed. AOA is used to give you as safety margin and the more advanced version (DBUS) uses AOA, weight and load factor to give a synthetic airspeed)
Having learned to fly light aircraft in Colorado USA with its snowy winters, the importance of COMPLETELY clearing snow and ice from the aircraft, not just the wings, was thoroughly drilled onto me as a safety of flight issue.
@@mapleextIn cases like this, where people decide to skip something that should be part of a usual routine, I assume that the accident time was not the first time the shortcut was used but likely was part of a slippery slide to where the shortcut has become an acceptable alternate routine. I imagine this or another pilot tried leaving without cleaning a dusting of snow from the top and, as nothing happened, eventually became comfortable with leaving any amount of snow on top.
@@ellicel Indeed, probably that was it what happened here. And one time the shortcut will take his revenge. They survived it only with very Good Luck and thanks to the Safety Features of Airbus.
@egatycasi delta allows 1/8 inch on the bottom of the wings because of cold fuel. Otherwise there would be deicing happening 8 months of the year where I live and its not a problem in small amounts there. Same with a layer of frost on top of the fuselage but a lot of snow must be removed.
Respect to Airbus for providing better tools to handle unreliable airspeed after AF447. Learning lessons from past tragedies is what makes flying safe. Too bad they were not used here. Edit: My post refers to BUSS, or Backup Speed Scale, which uses Angle of Attack data to provide a safe zone display for pilots to fly in the absence or reliable direct airspeed data. This feature was in fact used by the pilots of MH134 to safely land their plane after it took off with the pitot tube covers in place in July 2018. Petter talks about BUSS in this video at 20:00.
“comedypilot”, this channel is literally full of Boeing accidents due to some Pitot tube issue - sometimes ground issue(socks not removed), sometimes basically the same issue described here
@@thecomedypilot5894 You need to explain yourself better. Yes the yoke-position would have made it clear what was going on in AF447 case, but otherwise Airbuses generally have better flight-envelope protection than Boeings.
@@thecomedypilot5894 Uh, no. Far from the truth. AF447 crashed because Bonin could not keep the aircraft steady to fly straight and level for the short duration of the unreliable airspeed due to startle factor and did not follow unreliable airspeed checklist to deal with that. I agree if it was a Boeing, the chances of the accident happening would have been decreased due to linked yokes, force feedback, speed stability instead of flight path stability and stick shakers but to say AF447 crashed because it was an A330 is simply incorrect. The design of the A330 contributed to the accident but it did not cause it. Pilot error is still the main reason for that accident.
@@thecomedypilot5894 Some accidents in an Airbus could have been prevented if the aircraft would have been a Boeing, that is correct. But you cannot forget that the opposite is also true, some accidents in a Boeing could have been prevented had the flight been flown with an Airbus. And no matter the aircraft, no matter how much effort and money we invest in making flying safer, we cannot remove all mistakes or threats.
That was stressful. Like a lot of people here I'm surprised that this didn't end in total tragedy. Your videos are much better than "Air crash Investigations" etc. Thanks Petter.
When I heard that "Unfortunately the voice recorder was lost" I was wondering just how insane the impact must have been for it to be destroyed, I'm surprised this airplane landed safely. Edit: after watching the video again, I found the exact wording at 19:49 - 19:55 which said: "the cockpit voice *recording* was sadly lost", which was different from what I remembered when I wrote the comment. That difference of a few letters implies that the recorder was never lost, only what was recorded in it, which is normal since the flight lasted for way longer than what the recorder was able to record. But this brings me the question, why is it that the voice recorder does not have a capacity that exceeds the maximum possible flight time of the airplane? Wouldn't it be better to be able to spot any error, no matter how long the flight, and reduce guessworks?
Yes, when I heard Petter say that I couldn't have believed it was because the aircraft continued to fly for so long that the portion of interest from the recording would have been automatically overwritten. Strange that there isn't a "save for later" feature, a bit like with a car dashcam, so that you can mark a sector of the recording to be preserved for the remainder of the flight.
@@TheGOLDIdeluxe I am more surprised that no one dunked at manager who literally ordered to flew the plane from their landing point to almost same range as it original destination was "just because".
@@heckelphonI believe that is technically an option. The cockpit voice recorder has a circuit breaker that can be shut off, which will stop the recording from being overwritten at the expense of no longer recording. These cockpit voice recorders generally store recordings for a fairly short period of time (30 minutes to 2 hours depending on the plane from what I'm seeing).
I had a 36 year aviation career and I felt the beads of sweat forming on my forehead just listening to the story. I'm glad to hear that all landed safely, although, it sounds like that airliner is going to need some serious inspection due to the over speed and G loading.
Is that okay though that you had such an anxiety reaction as someone who flies? It doesn't look like this pilot had such an reaction while telling this story
Wow. I was unfamiliar with the event, and when things started going badly, more particularly when the pilots started reacting badly, I feared an all souls lost accident. I was so relieved when they landed it safely. Aa usual, your production values just get better, and your calm, no nonsense narration makes it perfect. Thank you for what you do!
Actually, it wasn't that, either. In the end, it was just that they flew so long after the incident that its audio was overwritten. They don't hold all that much audio; 2 hours I think.
On rewatch, it also is astonishing that they were able to escape the vertical speed of 15,000 feet per minute. That must have been absolutely terrifying for everyone on the plane, crew and passengers alike.
I can’t believe how close this was to a disaster. The air traffic controller did a great job but those pilots really didn’t handle the situation well. Hopefully they learnt a lot from it and became better.
That was 2021, and I doubt Russia got any more professional since then. Even read some articles about supposed counterfeit deicing fluid, which sounds more like an attempt to shift blame from the incompetent authorities and pilots.
@@termitreter6545 it is not about liquid, it was all the way about cowboy attitude of some pilots here. I used to read blog of some of the S7 pilot-instructors some time around 2010s, he used to express his worries about pilots thinking that they are smarter than those strict procedures, especially regarding deicing procedures. S7 used to be one of the most progressive airlines, first to introduce modern CRM rules and joining the same alliance as the emirates. And they used to face opposition from those older pilots who wanted to keep older ways of doing things so yeah/ And by older way they meant those chaotic times of russa's 90s. Being experienced some times means that you can be a little bit too stuck in the past unfortunately
Yes, I always assume that experienced pilots or doctors or whoever make mistakes too because they become set in their ways of 'predicting' or 'knowing' what they know, while someone young and new and fresh can see with new eyes and an outside perspective.@@SotonyaAcckaya
This is the second time I watched this, and I still held my breath several times during the episode till I couldn't! So glad that they landed safely without crashing!! Just wow! 😳
M-Dash I have as well, reviewing a number of times. Its a blessing that the passengers had an experienced crew, perhaps the age/experience as well. According to the video, since they had snow melting, effecting the pitot tubes, if so, they perhaps were receiving false reading/data. So basically they were experiencing a aerodynamic stall. Understand the dual inputs so basically the dual input would equal out. Could not imagine the g forces the crew/passengers were experiencing. They were in a stall, then experiencing an overspeed. What an experience, the passenger were experiencing. Thank goodness they were all strapped in. Thank goodness they decided to go to the alternative airport.
I am not a pilot and don't have anything to do with aviation, but still love watching your videos. Their quality is better than that of many documentaries on TV, and I learn a lot. Please keep up the fabulous work!
TV documentaries are little more than entertainment. They constantly restate the obvious, repeat the original premis and generally drag it out. If you are lucky, a 30 minute episode has 10 minutes of new content.
@@Dave5843-d9m I agree. Most of them I watch for entertainment, not information, or education. They are fun if watched that way. Otherwise, I get angry and upset with their ignorance.
I am so glad they were able to recover and no one died or loss of a beautiful plane, that always brightens my day when someone can fix a problem and stick it out till the end.
For the pilots who had been in such complete and utter distress to change plans from landing at their initial airport to flying across the continent, and _then_ to another airport entirely at the request of their company is jaw dropping. I'm sure they wanted nothing more than to put the wheels on the ground and go sit in a hot shower for an hour to decompress and let any adrenaline run its course.
@@MentourPilot Petter, I'd rather fly a Boeing with a proper old fashioned synchronous yoke in an emergency rather than this sidestick,normal law,alternate law,direct law nonsense.
Can we take a moment to appreciate how INSANELY good your graphics and visuals have become? Some crazy amount of work must be happening in the background! Thanks for sharing this chilling story.
Flying for that long after such a serious incident also has its advantages. It psychologically normalises faster than after having to emotionally 'spin down' away from the aircraft. Plus ofcourse the fact that it wipes the CVR clean. They weren't entirely unlucky.
my uncle once had a deer jump into his lap across the fuel tank of his motorcycle. he said he had to ride another mile before his legs stopped shaking enough that he dared to stop.
@@NicolaW72no, probably they had a technician in Irkutsk so it could handle plane and figure what is going on. While if they would land in Yakutsk - probably they would have either no help at all and after that somehow would need to fly potentially damaged plane from there.
hi mentour, airbus pilot here. i would like to correct some things in the video. firstly buss recives aerodynamic data from AOA sensors (as you discribed) as well as `Stall` warning in airbus. so captains reaction to trust stall warning was considerably understandable. BUSS was also showing that aircraft was flying too slow probably. its pretty reasonable that angle of attack sensors were affected by icing as well, in that case only action crew could do was applying memory items as you described. also in airbus, in alternate law pitch is still controlled by load factor, which is excatly the same as in normal law. so applying full back stick would have the same consequence as in normal law. only exception here would be in direct law, where pitch control is also direct like roll control. so best option in the given conditions is to apply memory items, climb to a safe altitute where icing is not a great threat and try to troubleshoot. pilots tried to do somehow, but i cannot put myself or any other pilot who did not experience such failure because this is a very hard failure to handle. i would like to thank you. although you are not an airbus pilot you covered everything very precise. you almost took type rating while preparing this video :)
If I may, this comes to basic aviating skills that an experienced crew should be able to handle. Pitch and thrust, at least N1, are not dependent on external sensors. Thrust MCT, pitch to moderate but known positive climb angle for MCT, monitor vertical speed. Monitor GPS altitude to confirm. Until clear of clouds. Aviate, as in aviate, navigate, communicate. When in unknown abnormal, aviate, always aviate.
Thanks for those details. I came here to say "pitch+power = performance" (kind of as per those memory items), and "at the end of the day, it's still an airplane, so fly it like one", but your comment makes me doubt my naïve intuition. I lived through pitot icing as well (over the Canadian rockies) and lost some altitude in IMC close to MSA until the problem was identified. Uncomfortable.
Do you know why pilots can't just see their altitude dropping very quickly + angle of plane being up and realize immediately they are in a stall even without sensors? Also I'd imagine if I'm in this video's pilot's situation and my speed gauges weren't reliable I could still approximate my forward speed with altitude change & angle of plane. Am I wrong that these bits of information can indirectly give you an idea of what is going on with the plane? Shouldn't that intuition be second nature to 10k+ hour pilots?
Once again, great recap of an almost fatal incident. Just a couple corrections: on the Airbus, the Stall Warning (Stall, Stall) is not based on the airspeed (like the Overspeed Warning), but rather on the AOA, that’s why it says to respect the Stall Warning in an Unreliable Airspeed situation. Also, later on, you mention that instead of flying straight ahead while applying the Climb THR and 10°NU Pitch, they turned right on the SID. The Unreliable Airspeed procedure does NOT prevent turning to follow the SID, especially if terrain is a factor. Great video. Thanks
@@UnshavenStatueNo, stall AOA is always the same. Think of it like this. If you're going slower, you need to have a higher AOA. This is covered in like day one of Private Pilot Ground School
@@UnshavenStatue No it doesn’t. Stall Angle of attack does not change. That’s why you must ALWAYS respect the Stall warning, even in Unreliable Airspeed conditions. Except at takeoff when it could be spurious, in this case you set TOGA and Pitch 15° NU.
The structural integrity of modern aircraft astonishes me. The amount of stress, that an aircraft can withhold, is absolutely staggering. Doing 2G and 20 feet above maximum speed in such rogue conditions is a miracle. This reminds me of the Pinnacle Airlines flight 3701, where the aircraft was bench-marked. I think, that the aircraft engineers and the entire team deserve way more kudos for the amazing piece of engineering they produce.
So happy that you are concentrating recent program topics on Investigations based upon dangerous 'near-miss' or 'potentially-catastrophc' events that do not end in a crash. The lessons learned from these events hold the potential to reduce future catastrophic events in the industry that can potentially cause a significant loss of life. Cheers
Just insane work made by all team to show it for us! Thank you to all mentor pilot team! At the time of this event happening, I’ve worked for s7 and it still shocks me and goosebumps me. More insane thing that aircraft after this roller-coaster just receive a minor damage which was repaired in a month, including all inspections and repairs by S7 Technics Engineers and Airbus inspection team
After watching a ton of these videos I'm noticing a pattern. It seems like the autothrust, autopilot, autotrim, ECT are excellent systems with great safety. But the pilots need a TON of knowledge in order properly understand how these systems react, which becomes even harder under stress. My hats off to you guys, your job is almost impossibly hard!
I'm a software designer and a private pilot - honestly, i'm astonished by the way that the control systems in these Airbus aircraft work, the idea of switching between different 'modes' where everything works differently in a complex, stressful scenario is simply asking for trouble. You would't make a word processor that way.... Its INSANE.
@@bwcdevices3028although I agree, I'm not sure if there could ever be a solution to this. Different things work, because some of the instruments become unreliable.
@@bwcdevices3028 the systems don’t become completely different, the systems degrade and you suffer a loss of functionality rather than it working differently. Eg from normal law to alternate law, you lose protections but you keep what are known as stabilities and in essence the jet flies the same. Degrade to direct law and you lose the stabilises and the jet flies like a conventional Cessna. Either way the laws of physics remain and any suitable qualified pilot should have no issue with it. It’s not as you suggest, that a word processor might all of a sudden start to type in another language or print everything in bold font. It’s all covered in the type rating and you are thoroughly trained to deal with these issues.
What a phenomenal amount of work must have put into this production! The animations alone are brilliant, as is your clarity when explaining technical issues. Despite the pilots acting unprofessionally, ignoring SOPs and memory items, you manage to not berate them. As always, you present a balanced and informative view. You were born to do this! Thank you! (Retired pilot, 23yrs on Airbus 330,340,350 and B744)
I couldn't agree more! Quick question that you may be able to answer: is the term PIO or pilot induced oscillations not used anymore in aviation? I'm not a commercial pilot of any sort (only hang gliders and paragliders/paramotors) and it was used a lot in my hang glider training a long time ago (although the slang term 'porpoising' was often used out in the field). The reason I'm asking is I was under the impression that it was a standard aviation term, but I've never heard Petter use either one, so I started wondering whether it's an old superceded term, or only a light aircraft / GA term, or if it's not used in Europe, or something else entirely, and thought you might have an insight. (I know YT comment section isn't the best place for this, especially relying on the patchy notifications, so if by chance you do reply and i miss it, I'll give a pre-emptive thank you now)
Had goosebumps during the entire episode. Almost a repeat of Af447. Whatever said and done,kudos to the pilots on recovering almost an impossible scenario!
realizing the trim issue while being in distress thinking the controlls weren't working probably suggest they were able to look outside the box, i've seen too many crash videos to know that a lot of pilots get stuck in tunnell vision and bias sometimes not being able to see simple things infront of them @@przemho0
Wow, thank you very much, the story was conveyed in a really exciting manner! I felt relief when heard that they managed to land successfully, I expected them to crash. It is astonishing how much effort is invested into these videos!
Looking through the comments, it's so cool how much you interact with the community! I'm always nervous about flying after watching these videos, but I'm also always glad they come to such an in-depth dissection of what happened and how to prevent it.
Thank you for your nice words. My goal is to show the in-depth analysis that follows these events and how lessons from previous accidents (like AF447 in this case) help with new incidents.
Every single man and woman in a flight and cabin crew, from attendants to pilots are heroes to me. I am terrified of flying, so I have no idea how you folks do it. Hats off to every single one of you. 😀
I initially learned to fly in Australia, in the coldest city in Australia but none the less a country where -5deg is cold. When I moved to Canada I learnt what weather is, how to handle it and how to never muck about with it! Just fantastic that this video ended with no injuries.
Thrilling episode once again, great job. As someone who has flown S7 many times in the past I hope they have improved and learned from this. Although it's easy to be an armchair pilot, the fact that they did not use the backup speed combined with the long duration until they noticed trim, really paints an unfortunate picture of under-training of this crew!
I discovered your channel a few days ago and I've been mesmerized by all those stories, the way you tell them and the detailed and instructive simulations. This is an amazing channel, please keep up the great work!
I feel like the Normal Law / Alternate Law / Direct Law can create so much confusion about which systems are working and which are not. Pilots need to really know the systems inside and out in order to make sense of them - in a high stress situation, the confusion can easily become overwhelming.
Yes exactly. I feel like airbuses are created by French computer scientists! The problem is that in airbus you are training pilots to be irrelevant which is fine until things go wrong and then they need to be super human. Which is ok until they are inexperienced and tired…
Yeah, there should only be 2 modes, full autopilot where the plane flies itself, and manual mode where you do everything. If the plane ever enters manual mode, it will not switch back to automatic without the pilot's command. Yes, that means the pilots will need to know how to fly a plane in manual mode. But it's what they've been trained on since day 1 in flight school, so I would expect them to be able to handle it.
A number of crashes have been caused by inexperienced piolts not understanding alternate and Direct law modes and that the flight "joystick" stick can operate different modes (and they are Not force feedback so they don't give any tactile feedback of what the plane is doing and what the other pilot is doing, the similar fly by wire Boeing 777 Dreamliner uses Force Feedback to simulate mechanical feedback you normally get on direct hydraulic controled planes and each stick can be deactivated so piolt can easily move out or deactivate a faulty stick) Af447 co-piolt was wanting 5% up angle up (due to speed tuped got iced up) but it changed to the mode that just changes it to set a angle an holds when you let go of the stick, so he was constantly telling the plane to goto max angle that alternate law allowed due to the temporarily unreliable speed due to ice but due to putting the plane in a maximum nose up the plane could not go back to normal law and he never told the captain that he was doing this until they were 20seconds from hitting the water (this is why on most airlines now you can be fired for using avg mode on the sticks and must make sure you taken control prirorty when your taking control, as captain actions was been countered by co-piolt due to the plane on Af447 using avg mode between the 2 sticks)
@@leexgx The only safe way to fly an airbus, is for one pilot to take care of the flying while the other is monitoring the instruments and giving verbal communications when required. Switching the control sticks to priority takes time and is confusing. If one pilot (normally the captain) needs to take control, he simply needs to instruct the other to release his sidestick and not use any other inputs. Perhaps the one exception in difficult conditions, is the pilot monitoring to take care of the throttles and trim, but everything needs to be constantly verbalised. One major problem with Airbus, is pilots loosing their skills of manual flying. One airline that I am connected with, insists that one short flight every week is flown entirely manually. This is logged and if for any reason missed, has to be explained to the chief pilot. If the crew are regularly flying long haul, they fly manually during the first and final hour of the flight. Needless to say, instrument landing is allowed if the weather is poor. Largely due to the skills of their pilots, the airline has not had a crash or incident involving injury in more then 55 years.
@@MentourPiloti heard atc record and read finale report. Chills was all over my body. And did you heard about recent incident with a320 wich landed in the wheat field?)😂 Same airline of corn field miracle.
dropkicknazis5301 you have to realize that Petter is from a Scandivian country ie: Sweden. Even though English is his second language petter perhaps speaks the language better than most individuals.
Wow, I didn't actually think they were going to survive this... Great video, as always. I especially like the fact that you expain what's happening in a way that I (as a non pilot) can understand and follow the chain of events leading to a certain outcome. Your videos surely have shown me that there is A LOT more to piloting an aircraft that just pushing around a stick a little :)
I wonder if real pilots undergo some kind of training that includes learning about past catastrophes. I've watched some episodes on TH-cam here and there, and even I know about the pitot tubes (whatever they're called). There was at least another accident caused by a problem with those, in South America, I think. The pilots could not tell the speed of the plane. Anyway, I hope actual pilots learn about past accidents, it would definitely help them.
Omg 😢 that was INTENSE. I’d bet those passengers have an incredible new perspective on their lives. Staring certain death in the face, and then finding yourself walking off the plane safely on the ground 🙌
I fly a lot, as a passenger… this is great content but holy hell it’s scaring the crap out of me. I’m just glad you speak about changes made after these accidents.
@@EviGL since you can neither see outside far enough nor have flight displays available a passnger it is quite possible you wouldnt even notice as passenger..
@@unitrader403 Have you ever actually been in a plane? Because I can tell you that you would 1000% notice a goddamn *90 degree roll* when its already possible to feel the plane turning to line up with the runway.
Being a student pilot, I learn something new every time I watch your videos. Not only are they full of details (no drama, you explain well things as they are🎩), but also, are they full of knowledge and very instructive. You're our long-distance instructor🫡
Hey Petter, you and your Crew are doing a absolutely mega job for each episode. Don‘t know, if there is any better aviation content on this platform and you still seem to be a very humble person 😌 hope to fly with you some day.
As somewhat of an air crash investigation nut, but not a pilot, it was hard for me to describe why I feel that AB pilots have worse outcomes when they're called to actually fly the plane. This video does a great job even for a nonpilot like myself to shed light on the factors that play into that. Thanks @MentorPilot!
This was very well explained! It must have been a _chilling_ experience for all those involved, especially with so many issues like the stall and the dive. Glad to see them safe in the end! Great research done by your team, keep it up!
Thank-you for all your aviation videos. 50 years ago I was an RAF cadet and although I flew props and gliders as a cadet, my eyesight disqualified me as a full-time jet pilot. I am now a retired engineer and have both worked in aircraft manufacture and been a frequent flyer. Your technical detail is always fascinating.
I couldn’t imagine that they’ve actually made it safely to the ground. What an incredible, indestructible bird, and one hell of a Hollywood-class nerve wrecking episode!
The unending cycle of dives must have been terrifying to experience. I was horrified when you mentioned the switch from alternate law to direct law and vice versa, and the effect it had on the plane. If the Auto-trim had not been noticed and corrected, this would have been a disaster. Thank God it ended the way he did! Amazing episode once again Peter. Always a pleasure!
Wow I'm from Russia and I never heard of this incident! Great video and kudos to everyone who helped you with report translation. S7 is pretty good airline for russian airlines, so the whole video I tried to believe that they'll make it. Glad that they did.
Yeah kinda didn't expect this from S7... If that's the type of stuff happening with our more respectable airlines, I struggle to imagine the level of buffoonery of Red Wings or, for example, Ural Airlines. Jeez
@@ivantorubarov5541well idk s7 is just rebranded siberia and I have a particular childhood memory of like several siberia planes crashing in one year so i don't trust s7 despite the rebranding
@@alexandracotton4514 they went through a lot of deep modernisation in both the fleet (e.g. ditching all their old Soviet planes) and procedure in the early 2010's, but I would imagine the last few years weren't particularly conductive to upholding standards...
This might have been a more terrifying situation for the passengers, and crew, than most actual crashes. I felt so bad for the passengers during the rollercoaster oscillations.
Amazing and by your language, I was expecting a crash at the end. Instead, they calmed down during that 2-hour alternative landing flight and survived. It was a fabulous story for pilots or crazy people like ME who are simply interested. (I will sail or walk hereafter.) The lead author is VERY good! Sell this for a movie script!!!
It could've been frustrating to listen to what, and when the pilots did this or that, but you're very good at explaining, and making most of their actions understandable.
But the remarkable thing is how many mistakes they made that were not understandable. This is unusual, most of these incidents involve little to no pilot error beyond what is inevitable when faced with a selection of bad choices. Here there were many good potential choices which could have prevented or ended the upset at multiple points.
I find your videos incredibly relaxing, it’s like every time I turn on a Mentour video, I feel like all my problems fly away. Your videos are really enjoyable and informative, thanks for making everyone’s days a bit better.
This video was thrilling and frightening as well. Thank you Petr for your in depth knowledge and real life explanations taking place. My 20 year old is preparing for her first solo in about three weeks. I pray in her future career she doesn’t experience anything such as this.
Don’t worry about your daughter- as long as she has a great attitude and a willingness to learn : a strong aircraft knowledge and practical aviation( what used to be called “stick and rudder” skills) and an ability to think laterally and stay calm under pressure but still Follow procedures, practice great CRM then She would deal with the situation like this well - look at Petter who present this channel you can see how he would be in a similar situation.
Unreliable airspeed is not really a problem. Once upon a time I was a baby pilot and my Flying Instructor told me to set a power of 80%, select an attitude of about 15 degrees nose up and Trim (manually), without looking at the ASI... This configuration gave around 180 knots in the climb (some of you may know the aircraft in question?). Power Attitude Trim (PAT). Thereafter, every aircraft I flew, I nailed and memorised the PAT numbers for climb, descent, turbulence, endurance or level flight into my mindbox. The modern aviation world is full of helpful software and systems but PAT awareness would solve many of the issues I see in this technological world. My father was an ex Bomber Command Aviator and his baby pilot was the flying instructor that gave me that advice about PAT.
I was holding my breath, waiting for that crash. That they flew another 4.5 hours before landing is a miracle. That none of the passengers was injured is the icing on top. But I can only imagine the terror they must have felt during those hellish minutes. Thanks Petter for another amazing video.
Nobody was injured because they don’t get paid 20k for being sick and getting a headache like in the US. If this happened in the United States they would have had 100+ injuries.
As soon as Petter said "he turned on the window heating" I knew what was gonna happen. After watcjing hours of his videos I've learned quite a bit anout aviation it seems. Great video as always, thanks Petter!
I rarely become so engaged with a story but this one had my heart racing and a huge relief that they actually managed to regain their faculties and control.
I couldn't fathom sitting there for 2.5 more hours as a passenger while having no idea what caused all of that and if it could happen again. That had to be such a high stress load.
I was always a nervous flier, but since I was diagnosed with panic attacks I really hate flying. But interestingly I love watching Your videos. As many mentioned before, Your videos and content are top-notch quality. Also, I really like You as a person and I like Your personality. Many thanks for everything and kindest regards
Thank you for doing an excellent job covering unpleasant data! It’s amazing how much we can learn from others mistakes. You allow something good to come out of these mistakes in this app and human error
C'mon Petter, -12С in Siberia is almost summertime weather 😊. I am saying it as a person who managed to survive a 15 minute fast walk at -50C at 4am. And despite the fact that I was quite accustomed to temperatures like -30C or even -40C that experience was really special. I knew if I stop or fall, I will freeze there to death.
@MentourPilot even a little turbulence gets me pale as a sheet! I think I'd need years of therapy after this flight, even if I did just think it was storm turbulence, haha 😅
@@MentourPilot I don't see how that would be a possible interpretation from a passengers POV - Multiple 2g Climb phases after stall events where in was severe enough to spike roll
When you mentioned the pitot tubes, I instantly thought about AF447 and was like "Not again"..Not very far from that outcome either. Crazy how much that airframe withstood.
As UK ground crew, this one is a little close to home. We’re entering our winter season and that means a lot of winter operations for us. De-icing an aircraft is fun, but also a very serious responsibility. Gotta admit I prefer to de-ice Airbus planes. Oh how many times I’ve been on a ground vehicle like that. It’s fascinating to see it from the perspective of a pilot-and the lack of pushback truck explains why ground crew never spotted the ice on the pitot tubes and AoA sensors. Thanks for the high quality video and information about this incident.
the ice did not form on the pitot tubes. When the pilots turned on all the anti-icing systems, the snow and ice from the heated glass melted down and immediately froze, forming small ice streams. These thin streams of frozen water became the center of icing, the ice accumulated on them and blocked the air flow into the pitot tubes, while all the pitot tubes did not freeze, the ice formed in front of them. Also, this was not the only place where ice formed, if you look at the photo of the plane after landing, you can see that even after 4.5 hours of flight, the plane was full of ice, including on the aerodynamic surfaces
There's 2 reasons that cause aircraft to crash....... either technical issue or pilot error, however...... 99.99% of the time, they can and do fly us around the World and keep us safe. Massive respect from me goes to aircrew all over the World....... you're amazing!!!
As an Indonesian every time I hear about pitot tube problem my memory brings me back to the deadly accident Air Asia flight 8501. I am glad this flight 5220 has a good ending. Thank you for your amazing work with your Mentour Pilot team.
The Air Asia 8501 was perfectly flyable, with a minor ECAM warning. But the captain shut down the computers and that was prohibited during flight. After that they lost situation awareness and could not fly manually.
@@sarkisi Indeed. Problems with the Pitot Tubes caused a couple of horrible Crashs, the most infamous still is Air France Flight 447. But Air Asia Flight 8501 is not amongst them. It was a Maintenance Issue (a repeating technical failure wasn´t cleared), the Captain who shutted the Computers down in a non-understanding how the System worked and the First Officer, who was the Pilot Flying, who suffered a somatic illusion and made therefore erratic control inputs - and finally the miscommunication between Captain and First Officers. But not a problem with the Pitot Tubes.
It would be a good idea for actual pilots to watch some of these videos. They may learn something and I'd feel even safer flying! Keep up the good work..great channel and content.
Not only that, usually when some shit happens somewhere - after pilots (or technicians depending on who fucked up) gets a heads up. "Look what kind of shit happened there! It can happen to you! Don't do that here!" kinda.
The production quality keeps improving! This is legit professional documentary work. There HAS to be an award appropriate to this channel which I'm sure Mentour would win!
And I thought I had a bad day at work. Having to fly after that... Luckily no one got hurt after ALL OF THAT! It's insane how much punishment planes can take and still fly. Props to Airbus
What a great look at this incident. Glad to see it turned out okay. Luck was definitely on their side. I can't imagine how difficult it would be to just be calm and analyze the situation while all of this was going on. I suppose that's what training is about. Cheers!
Please make a video about miracle landing of Volga-Dnepr Airlines Flight 4066. Shortly after take-off the No. 2 engine of the Antonov An-124 Ruslan operating the flight suffered an uncontained engine failure. Debris from the engine punctured the aircraft's fuselage and wings, affecting power supplies and rendering the ADS-B inoperative. The aircraft's braking system was also affected, as were engines 3 and 4. Communications with air traffic control were also lost. The plane turned out to be without power, almost all the instruments in the cockpit went out. Engine 2 was lost, Engine 1 was in uncontrolled thrust mode, control problem with engines 3 and 4 The aircraft became almost completely uncontrollable. But the crew managed to land it!!!!
@MentourPilot no final report from the Interstate Aviation Committee yet. But the incedent is well documeted, and has extensive coverage by witnesses reports and even video records. There is even an interview with the commander of this aircraft about the details of the incident. The technical side of the incident has already been published in basic detail, the investigative organization - the West Siberia Investigative Department -was occupied with the question of who is legally to blame for the engine failure.
The first plane I flew on by myself. It was winter 1981, it carried less than 50 people, I felt like I had the L1011 all to myself. We had a beautiful view of Yellowstone and the Tetons.
Peter i love your videos and the way you explain them i used to be scared of flying so much that I didn’t fly more than once a yr but now thanks to you explaining things amd 74gear and captain joe I understand what’s happening most of the time amd fly wayyy more comfortably so thank you for everything you do I really appreciate your work I will be rewatching your videos until you post the next one because everytime I watch them i learn something new from them
I can't believe these two pilots were trained and tested for this kind of procedure, scored well, and still absolutely panicked and only didn't crash because ATC and the plane doing everything in their power to help them.
That's kinda how it works doesn't it? Everyone is trained to deal with it and yet everyone who crashes did so because they failed. All the training in the world doesn't mean diddly squat unless IT is what comes to your mind in a situation like that.
@@michaelbuckers Well...no. Absolutely not. Most crashes on this channel happens for severe mechanical circumstances, pilots not knowing what the problem is or just bad piloting. There was no mechanical circumstance, there was literally a list to follow and one button to push, then to safely go trough the procedure. 90% of this incident is the pilots absolutely panicking for something they were trained to. Your comment is very disingenous because it implies that training is useless, but its not. A lot of crashes are avoided by competent pilots in this very channel. These two literally ignored any basic point of their training and gave to fear, and the only reason they didn't end in a mountain is because the ATC screamed it at them.
@@CrowMercuryWell to be fair, it wouldn't be much of a video if the unreliable airspeed warnings are dealt with as per the manual and everything proceeded fine after that.
As this was Russian and I have watched a few of your content about Russian crashes so I was expecting this to have a tragic ending. But thank God! I really felt for that first commander. I can see myself reacting the same way
Great analysis and first time I'd heard about the backup speed/altitude system, airbus created after 447. Seems like a good way to remind pilots of pitch plus power equals performance, sad they didn't follow it.
Oh my goodness, i’ve had sooo many videos of yours in which i hoped for a good outcome. But this one really really was the one i cannot fathom the huge fears everyone on board had & then have to fly for a few more hours even!! I am really really glad they landed safely! Even tho big mistakes were made, the pilots never stopped fighting, flying en they never gave up & that is something i have tremendous respect for! Thank you for another amazing video!
This is about piloting. If you know the wind, know the plane, you know what thrust you should have. Just keep that, keep level, and you'll get out of it soon enough. Just keep a close eye on the ADI.
This video has the best explanation of the airbus 'laws' I've seen yet - been confused about those for a while and this cleared it right up. Thank you!
Given how many Pitot incidents there have been over the years you would think that "Snow" plus "unreliable airspeeds" would automatically mean the pitot tubes have frozen. Given that the engines were working fine you would think that you would set a throttle position and pitch angle for safe flying and that once set a "stall" wasn't possible. Since they knew the airspeed was unreliable it seems crazy to me that they react like this.
@@BigHenFor I mean, that was basically what they were supposed to do based on the memory items, no? Its pretty simple, other pilots even managed it successfully which lead to that backup airspeed bar that gets briefly mentioned then apparently ignored by these pilots, despite this being exactly the situation it was created for.
They were startled and in panic and forgot how to deal with the upset. Plus, it's russia so I have my doubts about the quality of their pilot training.
Yeah yeah good but they also thought that their wings are also being covered with ice during flying through clouds, so it's completely understandable that they expected wings to lose some of it's lift and be prone to stall
@@johnny_ethlet’s say, there are pilots who do not take their training seriously. Add some complacency and you are full set. I work for S7 and if one wants to be a good pilot, this company gives the means to be.
Yet another awesome video! It makes my day when I wake up to a new Mentour Pilot Video. It is also shocking just how many incidents relate to the pitot tubes.
11:20 As soon as you said they were leaving the snow on the fuselage, I thought about the possibility of interference with the pitot tubes and/or angle of attack vanes.

My nightmare is still that I'm on an airliner that starts misbehaving, I turn and Mentour is sitting next to me saying "Aaand this is when things start to happen really quickly".
I have dreams about the 'PULL UP' alarm.
@@MrOnionterrorTOO LOW! TERRAIN. TOO LOW! TERRAIN.
@@InventorZahran Seriously, the "Fifty... fourty... thirty... twenty... ten..." at the start of each video stresses me out. And no, I don't care whether that's supposed to happen during a normal landing.
@AubriGryphon you get stressed out easily there is medicine and or therapy for that
Even if things get really bad, there will always be several YT commercials before whatever finally happens, happens. Those extra minutes should help the crew sort things out. 🙂
Kudos to the ATC, he saved their lives several times.
Yes.
I wonder if there is an equivalent award to ATC staff - this was truly superb ATC
absolutely
Right. The only hero in this whole story. (Apart from the plane itself, which probably endured stress well-beyond its design limits).
Planes are thunkfully a lot tougher than their technical max limits, another great example was Fedex Flight 705, the plane did upside down fighter jet manouveres while they were fighting in the cockpit.
You could easily think that watching these videos would make you a nervous passenger. But instead it's the opposite. Your calm voice and detailed technical analysis what had actually happened during the flight at least makes me much more confident and relaxed when sitting in plane. Thank you.
That’s what I was aiming for!
On the contrary, the fact that the pilots were so confused and mishandled the aircraft so badly, only increases my anxiety about flying. So much of what the pilots did was completely inappropriate, as if they didn’t know how to fly the plane.
Nope, I am amazed with the level of tech pilots have accepted: They are nothing more than Werner's monkeys.
I have to agree this way better then the clickbate "worst ever possible accident" and they scream in your ear about some cessna that got minor damage after it landed too fast.
I'm.... unconvinced. The number of times pilots become baffled by things that should be obvious (to them as experts), and the number of times blocked Pitot tubes have been the source of nasty accidents or incidents and STILL not been checked pre-flight or recognised as the issue during flight scares me rigid. You cannot convince me this won't happen again.
The editing on this video was awesome, I didn't hear anything about this incident before and I cannot believe that this wasn't a disaster accident and everyone survived this terrifying experience
Yeah, the report have been out only in Russian so it’s not very well known
If I was a passenger on that plane I would have never flown again! I would have driven a car for 2 weeks through Russia just to get back home.
@@MentourPilot Just like AF447, Airbus aircraft for some reason seem to confuse the pilots when switching between normal law/alternate law and direct law. Couple that with stall warnings/overspeed warnings which makes even experienced pilots struggle to figure out what's going on and what steps they need to recover the aircraft. I'm not sure whether more training is needed or an Airbus system change to make it less complicated.
@@Robert_N yeah I can imagine it's damn near impossible to tease out complicated programmed logic such as "if this flight control law changes to that flight control law, so and so will happen meaning such and such control surface will behave in this or that way requiring this particular corrective action" while plummeting towards the ground at 500km/hr. Works great for a computer, but the human brain is not designed to engage in such multi-step logic while in a high stress environment.
@@Robert_NIt's not affectionately known as the Scarebus for nothing you know...
The graphics, The animation, The microphone, The message..... I am very very impressed with this episode.
Thank you!! Glad to hear that
I’ve kind of binged a bit on his videos, and while there is a noticeable improvement, these videos are started out excellent (at least as far back as 3 years ago). The improvements have been steady and gradual and I agree with you 100%, this one is on par, if not better than a “network TV” production. We could easily pit this video up with a Discovery Channel, TLC, NBC, CBS or Netflix production and no one would be able to notice anything “inferior”. To me, he started the channel with an already superior level of professionalism & technical abilities and he’s just continued to get better and better. Awesome work! 🤠👍🏼
@@ricktaylor14001 I was just getting ready to say this before I read your reply. The quality increase has been steady rather than in big leaps, but the quality has reached the point that it is as good or in some cases better than the TV documentaries that used to be more common.
Same. So impressed, I didn't even skip the ad!!
Some colorglitches tho, on 21:01 - 21:02 for example.
I cannot believe they survived that whole ordeal... UNREAL!!!
Yeah and then proceed flying like nothing happened for another 3 hours
With all those mountains in the area, the highly attentive ATC controller is likely a big reason they didn't fly straight into one while being disoriented!
They have highly effective alcoholisation procedures in Russia, I'm told.
How Russian is that? 🤣
NEVER should have been allowed to take off. Russia is junk now. Most of their tech is 1980s .
Hi, just FYI to people who werent sure if the passengers were aware of what was going on -- they were. One of the flight attendants was giving an announcement about S7 Priority program when things first started to go wrong, and she stopped mid sentence and didnt continue. The passengers were told to put their seat belts on, and from there on just were sure they were going to die. They said no one panicked, everyone was quiet and going through it internally.
One of the passengers said that there wasnt even a point of taking a video either because they were going to crash and the phone's going to burn anyways. Afterwards, the media dubbed it the "scary fun" flight, which doesnt work as well in the direct translation, but can loosely be interpreted as "terribly fun" flight
(Source is an interview in Russian)
My god that must have been terryfying and as I was watching the video, I had this awful feeling inside that they all died.
Same
Reminds me of the vomit comet where they induce weightlessness by pitching down and up. I bet stuff was floating around in mid air during that flight.
"terribly fun" as in "ужасно весёлый полёт"?
There was that one plane crash in India where the guy was recording as they were about to land, only for the plane to crash and the phone somehow survived in the flames and fire. It is totally possible a phone could have survived.. so always film on the plane!
he was live streaming thats why, the phone was gone@@casedistorted
At points I was completely sure this was going to be a crash case.
Props to... Airbus for building an aircraft sturdy enough to take this kind of punishment. I guess?
I wonder just how many flight hours this nonsensical farce ripped from that airframe
@@bengrogan9710I would be surprised if the aircraft was not a total write off or at least due for some major inspection and overhaul after this incident.
Then again I also would not be surprised if the aircraft was just put back into service after this with only a few forms filled out saying maintenance had done the required inspections after doing absolutely nothing. I also would not be surprised if the pilots never received proper training on unreliable airspeed in the first place. I may be wrong though, I don't know as much about the Russian airline industry and whether they have effective processes in place to mitigate the culture of corruption which is so rampant in the rest of the Russian economy and state.
I saw a video where they tested an A380 wing by bending it till 90 degrees. The wing survived all that.
@@Tekker2234 Calm down boomer, the rest of the world is just as corrupt
@@MattyEnglandRussian aviation in particular has quite a bad safety record
I remember discussing the Air France 447 flight online, and arguing that there should be a standby mode for guessing the airspeed based on throttle and control surface settings, and GPS data. (And being told that I was a stupid head for even suggesting such a thing.) Glad to see Airbus actually developed something along those lines, and it's actually useful when used properly.
Why can't a fighter jet with radar be dispatched to assist the plane
@tanmaysingh267 Fighter jets can't really assist a plane in any meaningful way. Near an airport, they would be redundant, as ATC radar can be used to give height, speed, and direction - and is already on station.
Half way across the Pacific or Atlantic, there often isn't any fighter jets in range, and by the time the crew realise the problem, they're often less than a minute from death. And no fighter could reach them in time, even if they did have the range.
@@anticarrrot ATC's around the world barely use radar anymore,they rely on transponder data from the aircraft itself
@tanmaysingh267 Secondary radar is used extensively, for a variety of purposes, but primary radar is definately still in use. And 3d primary ATC radar is a decades old technology by now.
They might have to flip a switch to get the 3D data, but it's still there if they needed it.
GPS data is only for altitude and it cannot measure airspeed. AOA is used to give you as safety margin and the more advanced version (DBUS) uses AOA, weight and load factor to give a synthetic airspeed)
Having learned to fly light aircraft in Colorado USA with its snowy winters, the importance of COMPLETELY clearing snow and ice from the aircraft, not just the wings, was thoroughly drilled onto me as a safety of flight issue.
Good!!
Yes, and this is Siberia!!! Didn’t they know??
@@mapleextIn cases like this, where people decide to skip something that should be part of a usual routine, I assume that the accident time was not the first time the shortcut was used but likely was part of a slippery slide to where the shortcut has become an acceptable alternate routine. I imagine this or another pilot tried leaving without cleaning a dusting of snow from the top and, as nothing happened, eventually became comfortable with leaving any amount of snow on top.
@@ellicel Indeed, probably that was it what happened here. And one time the shortcut will take his revenge. They survived it only with very Good Luck and thanks to the Safety Features of Airbus.
@egatycasi delta allows 1/8 inch on the bottom of the wings because of cold fuel. Otherwise there would be deicing happening 8 months of the year where I live and its not a problem in small amounts there. Same with a layer of frost on top of the fuselage but a lot of snow must be removed.
Respect to Airbus for providing better tools to handle unreliable airspeed after AF447. Learning lessons from past tragedies is what makes flying safe. Too bad they were not used here.
Edit: My post refers to BUSS, or Backup Speed Scale, which uses Angle of Attack data to provide a safe zone display for pilots to fly in the absence or reliable direct airspeed data. This feature was in fact used by the pilots of MH134 to safely land their plane after it took off with the pitot tube covers in place in July 2018. Petter talks about BUSS in this video at 20:00.
@thecomedypilot5894 This wouldn't happen with a Boeing?
*Looks on over to the MAX*
Suuuuuure.
“comedypilot”, this channel is literally full of Boeing accidents due to some Pitot tube issue - sometimes ground issue(socks not removed), sometimes basically the same issue described here
@@thecomedypilot5894 You need to explain yourself better. Yes the yoke-position would have made it clear what was going on in AF447 case, but otherwise Airbuses generally have better flight-envelope protection than Boeings.
@@thecomedypilot5894 Uh, no. Far from the truth. AF447 crashed because Bonin could not keep the aircraft steady to fly straight and level for the short duration of the unreliable airspeed due to startle factor and did not follow unreliable airspeed checklist to deal with that. I agree if it was a Boeing, the chances of the accident happening would have been decreased due to linked yokes, force feedback, speed stability instead of flight path stability and stick shakers but to say AF447 crashed because it was an A330 is simply incorrect. The design of the A330 contributed to the accident but it did not cause it. Pilot error is still the main reason for that accident.
@@thecomedypilot5894 Some accidents in an Airbus could have been prevented if the aircraft would have been a Boeing, that is correct. But you cannot forget that the opposite is also true, some accidents in a Boeing could have been prevented had the flight been flown with an Airbus.
And no matter the aircraft, no matter how much effort and money we invest in making flying safer, we cannot remove all mistakes or threats.
That was stressful. Like a lot of people here I'm surprised that this didn't end in total tragedy. Your videos are much better than "Air crash Investigations" etc. Thanks Petter.
When I heard that "Unfortunately the voice recorder was lost" I was wondering just how insane the impact must have been for it to be destroyed, I'm surprised this airplane landed safely.
Edit: after watching the video again, I found the exact wording at 19:49 - 19:55 which said: "the cockpit voice *recording* was sadly lost", which was different from what I remembered when I wrote the comment.
That difference of a few letters implies that the recorder was never lost, only what was recorded in it, which is normal since the flight lasted for way longer than what the recorder was able to record.
But this brings me the question, why is it that the voice recorder does not have a capacity that exceeds the maximum possible flight time of the airplane? Wouldn't it be better to be able to spot any error, no matter how long the flight, and reduce guessworks?
Yes, when I heard Petter say that I couldn't have believed it was because the aircraft continued to fly for so long that the portion of interest from the recording would have been automatically overwritten. Strange that there isn't a "save for later" feature, a bit like with a car dashcam, so that you can mark a sector of the recording to be preserved for the remainder of the flight.
@@heckelphon Yes, because you don't want to listen to the pilots and pax in the background screaming for 30 minutes 🙂
I think it was overwritten because the flight took so long after the incident.
@@TheGOLDIdeluxe I am more surprised that no one dunked at manager who literally ordered to flew the plane from their landing point to almost same range as it original destination was "just because".
@@heckelphonI believe that is technically an option. The cockpit voice recorder has a circuit breaker that can be shut off, which will stop the recording from being overwritten at the expense of no longer recording. These cockpit voice recorders generally store recordings for a fairly short period of time (30 minutes to 2 hours depending on the plane from what I'm seeing).
I had a 36 year aviation career and I felt the beads of sweat forming on my forehead just listening to the story. I'm glad to hear that all landed safely, although, it sounds like that airliner is going to need some serious inspection due to the over speed and G loading.
Is that okay though that you had such an anxiety reaction as someone who flies? It doesn't look like this pilot had such an reaction while telling this story
Wow. I was unfamiliar with the event, and when things started going badly, more particularly when the pilots started reacting badly, I feared an all souls lost accident. I was so relieved when they landed it safely.
Aa usual, your production values just get better, and your calm, no nonsense narration makes it perfect. Thank you for what you do!
Me too because he mentioned early on that CVR was sadly lost, I assumed in a severe crash but must instead have been a malfunction.
Actually, it wasn't that, either. In the end, it was just that they flew so long after the incident that its audio was overwritten. They don't hold all that much audio; 2 hours I think.
@@snapdragogon69 I presumed exactly the same thing. I was amazed when they did not crash at the end of the video just because of that.
On rewatch, it also is astonishing that they were able to escape the vertical speed of 15,000 feet per minute. That must have been absolutely terrifying for everyone on the plane, crew and passengers alike.
I can’t believe how close this was to a disaster. The air traffic controller did a great job but those pilots really didn’t handle the situation well. Hopefully they learnt a lot from it and became better.
Indeed.
That was 2021, and I doubt Russia got any more professional since then. Even read some articles about supposed counterfeit deicing fluid, which sounds more like an attempt to shift blame from the incompetent authorities and pilots.
@@termitreter6545 it is not about liquid, it was all the way about cowboy attitude of some pilots here. I used to read blog of some of the S7 pilot-instructors some time around 2010s, he used to express his worries about pilots thinking that they are smarter than those strict procedures, especially regarding deicing procedures. S7 used to be one of the most progressive airlines, first to introduce modern CRM rules and joining the same alliance as the emirates. And they used to face opposition from those older pilots who wanted to keep older ways of doing things so yeah/ And by older way they meant those chaotic times of russa's 90s.
Being experienced some times means that you can be a little bit too stuck in the past unfortunately
Yes, I always assume that experienced pilots or doctors or whoever make mistakes too because they become set in their ways of 'predicting' or 'knowing' what they know, while someone young and new and fresh can see with new eyes and an outside perspective.@@SotonyaAcckaya
we're all to blame, We've gone to far, from pride to shame, we're trying so hard, we're dying in vain,we're hopeless.
This is the second time I watched this, and I still held my breath several times during the episode till I couldn't! So glad that they landed safely without crashing!! Just wow! 😳
M-Dash I have as well, reviewing
a number of times. Its a blessing that the passengers had an experienced crew, perhaps the age/experience as well. According to the video, since they had snow melting, effecting the pitot tubes, if so, they perhaps were receiving false reading/data. So basically they were experiencing a aerodynamic stall. Understand the dual inputs so basically the dual input would equal out. Could not imagine the g forces the crew/passengers were experiencing. They were in a stall, then experiencing an overspeed. What an experience, the passenger were experiencing. Thank goodness they were all strapped in. Thank goodness they decided to go to the alternative airport.
I am not a pilot and don't have anything to do with aviation, but still love watching your videos. Their quality is better than that of many documentaries on TV, and I learn a lot. Please keep up the fabulous work!
After i found this channel i stopped watching those documentary's. This is the best of the best hands down

TV documentaries are little more than entertainment. They constantly restate the obvious, repeat the original premis and generally drag it out. If you are lucky, a 30 minute episode has 10 minutes of new content.
i think most of us arent pilots here
@@Dave5843-d9m I agree. Most of them I watch for entertainment, not information, or education. They are fun if watched that way. Otherwise, I get angry and upset with their ignorance.
i am 10 years old and i have learned everything i know about aircraft from you thanks☺
Awesome!! Stay focused in school and maybe we will fly together some day.

I'm 35 and have learned quite a bit from this channel and 74 Gear. It's never too late to learn, and you're never too young to. Keep learning!
A pilot in the making! ☺💯

I am so glad they were able to recover and no one died or loss of a beautiful plane, that always brightens my day when someone can fix a problem and stick it out till the end.
For the pilots who had been in such complete and utter distress to change plans from landing at their initial airport to flying across the continent, and _then_ to another airport entirely at the request of their company is jaw dropping. I'm sure they wanted nothing more than to put the wheels on the ground and go sit in a hot shower for an hour to decompress and let any adrenaline run its course.
Sounds about right.
Perhaps they quit their jobs right after due to trauma and have not flown since as passengers as well
This is Russia. You obey your leaders. No own initiatives.
Petter, its amazing how underestimated icing dangers are. Thus incident once again highlights the dangers- Thanks again for a brilliant video
Thank you for pointing that out. Winter-ops can be very dangerous if not handled correctly.
@@MentourPilot Petter, I'd rather fly a Boeing with a proper old fashioned synchronous yoke in an emergency rather than this sidestick,normal law,alternate law,direct law nonsense.
Yeah, in Magadan and Siberia they just get used to it, since snow and ice are everywhere more than 6 months a year.
Once in a while, when on a flight of thaf kind, had to Console Pilot, his face having turned to " green"
@@anand-menon I'd rather have a PlayStation controller and the controls be inverted in an emergency 👍 No point flying if you don't want a challenge.
Can we take a moment to appreciate how INSANELY good your graphics and visuals have become? Some crazy amount of work must be happening in the background! Thanks for sharing this chilling story.
Flying for that long after such a serious incident also has its advantages.
It psychologically normalises faster than after having to emotionally 'spin down' away from the aircraft.
Plus ofcourse the fact that it wipes the CVR clean.
They weren't entirely unlucky.
my uncle once had a deer jump into his lap across the fuel tank of his motorcycle. he said he had to ride another mile before his legs stopped shaking enough that he dared to stop.
Yes, indeed - and maybe this was the intention of the Company to redirect them to Irkutsk - and the Reason why the Pilots agreed to it.
Thats probably precisely why they didn’t mind flying an extra 2.5 hours
Implying a russian airline would do this to cover up pilots' mistakes before Airbus and not to make them work as hard as possible for maximum profits.
@@NicolaW72no, probably they had a technician in Irkutsk so it could handle plane and figure what is going on. While if they would land in Yakutsk - probably they would have either no help at all and after that somehow would need to fly potentially damaged plane from there.
hi mentour, airbus pilot here. i would like to correct some things in the video.
firstly buss recives aerodynamic data from AOA sensors (as you discribed) as well as `Stall` warning in airbus. so captains reaction to trust stall warning was considerably understandable. BUSS was also showing that aircraft was flying too slow probably. its pretty reasonable that angle of attack sensors were affected by icing as well, in that case only action crew could do was applying memory items as you described.
also in airbus, in alternate law pitch is still controlled by load factor, which is excatly the same as in normal law. so applying full back stick would have the same consequence as in normal law. only exception here would be in direct law, where pitch control is also direct like roll control.
so best option in the given conditions is to apply memory items, climb to a safe altitute where icing is not a great threat and try to troubleshoot. pilots tried to do somehow, but i cannot put myself or any other pilot who did not experience such failure because this is a very hard failure to handle.
i would like to thank you. although you are not an airbus pilot you covered everything very precise. you almost took type rating while preparing this video :)
If I may, this comes to basic aviating skills that an experienced crew should be able to handle. Pitch and thrust, at least N1, are not dependent on external sensors. Thrust MCT, pitch to moderate but known positive climb angle for MCT, monitor vertical speed. Monitor GPS altitude to confirm. Until clear of clouds. Aviate, as in aviate, navigate, communicate. When in unknown abnormal, aviate, always aviate.
Thanks for those details. I came here to say "pitch+power = performance" (kind of as per those memory items), and "at the end of the day, it's still an airplane, so fly it like one", but your comment makes me doubt my naïve intuition.
I lived through pitot icing as well (over the Canadian rockies) and lost some altitude in IMC close to MSA until the problem was identified. Uncomfortable.
@@davidsweltSo it is a jet so thrust no power.
@@aviationsummaries7919 every aircraft with an engine is no thrust no power- not just jets
Do you know why pilots can't just see their altitude dropping very quickly + angle of plane being up and realize immediately they are in a stall even without sensors? Also I'd imagine if I'm in this video's pilot's situation and my speed gauges weren't reliable I could still approximate my forward speed with altitude change & angle of plane. Am I wrong that these bits of information can indirectly give you an idea of what is going on with the plane? Shouldn't that intuition be second nature to 10k+ hour pilots?
Once again, great recap of an almost fatal incident. Just a couple corrections: on the Airbus, the Stall Warning (Stall, Stall) is not based on the airspeed (like the Overspeed Warning), but rather on the AOA, that’s why it says to respect the Stall Warning in an Unreliable Airspeed situation. Also, later on, you mention that instead of flying straight ahead while applying the Climb THR and 10°NU Pitch, they turned right on the SID. The Unreliable Airspeed procedure does NOT prevent turning to follow the SID, especially if terrain is a factor. Great video. Thanks
Well doesn't the critical alpha depend on the airspeed? Stall alpha at 80 kias is quite different from stall alpha at 250 kias...
@@UnshavenStatueNo, stall AOA is always the same. Think of it like this. If you're going slower, you need to have a higher AOA.
This is covered in like day one of Private Pilot Ground School
@@richardmillhousenixonand instrument and commercial and cfi lol
@@Aerogamer158 Yes, but everybody pretty much starts with PPG regardless of where they plan on stopping
@@UnshavenStatue No it doesn’t. Stall Angle of attack does not change. That’s why you must ALWAYS respect the Stall warning, even in Unreliable Airspeed conditions. Except at takeoff when it could be spurious, in this case you set TOGA and Pitch 15° NU.
The structural integrity of modern aircraft astonishes me. The amount of stress, that an aircraft can withhold, is absolutely staggering. Doing 2G and 20 feet above maximum speed in such rogue conditions is a miracle. This reminds me of the Pinnacle Airlines flight 3701, where the aircraft was bench-marked. I think, that the aircraft engineers and the entire team deserve way more kudos for the amazing piece of engineering they produce.
The problem that the monkeys who got their seats due to corrupted structure can ruin any type of greatest engineering work...
So happy that you are concentrating recent program topics on Investigations based upon dangerous 'near-miss' or 'potentially-catastrophc' events that do not end in a crash. The lessons learned from these events hold the potential to reduce future catastrophic events in the industry that can potentially cause a significant loss of life. Cheers
Just insane work made by all team to show it for us! Thank you to all mentor pilot team!
At the time of this event happening, I’ve worked for s7 and it still shocks me and goosebumps me. More insane thing that aircraft after this roller-coaster just receive a minor damage which was repaired in a month, including all inspections and repairs by S7 Technics Engineers and Airbus inspection team
Thanks for that input! Glad you enjoyed it.
Impressive that the airframe and components were mostly undamaged.
After watching a ton of these videos I'm noticing a pattern. It seems like the autothrust, autopilot, autotrim, ECT are excellent systems with great safety. But the pilots need a TON of knowledge in order properly understand how these systems react, which becomes even harder under stress. My hats off to you guys, your job is almost impossibly hard!
I'm a software designer and a private pilot - honestly, i'm astonished by the way that the control systems in these Airbus aircraft work, the idea of switching between different 'modes' where everything works differently in a complex, stressful scenario is simply asking for trouble. You would't make a word processor that way.... Its INSANE.
@@bwcdevices3028boeing does the same
@@bwcdevices3028although I agree, I'm not sure if there could ever be a solution to this. Different things work, because some of the instruments become unreliable.
Watching Petter's videos should be mandatory for student pilots. Possibly with a follow-up test.
@@bwcdevices3028 the systems don’t become completely different, the systems degrade and you suffer a loss of functionality rather than it working differently. Eg from normal law to alternate law, you lose protections but you keep what are known as stabilities and in essence the jet flies the same. Degrade to direct law and you lose the stabilises and the jet flies like a conventional Cessna. Either way the laws of physics remain and any suitable qualified pilot should have no issue with it. It’s not as you suggest, that a word processor might all of a sudden start to type in another language or print everything in bold font. It’s all covered in the type rating and you are thoroughly trained to deal with these issues.
What a phenomenal amount of work must have put into this production! The animations alone are brilliant, as is your clarity when explaining technical issues. Despite the pilots acting unprofessionally, ignoring SOPs and memory items, you manage to not berate them. As always, you present a balanced and informative view. You were born to do this! Thank you! (Retired pilot, 23yrs on Airbus 330,340,350 and B744)
I couldn't agree more!
Quick question that you may be able to answer: is the term PIO or pilot induced oscillations not used anymore in aviation?
I'm not a commercial pilot of any sort (only hang gliders and paragliders/paramotors) and it was used a lot in my hang glider training a long time ago (although the slang term 'porpoising' was often used out in the field).
The reason I'm asking is I was under the impression that it was a standard aviation term, but I've never heard Petter use either one, so I started wondering whether it's an old superceded term, or only a light aircraft / GA term, or if it's not used in Europe, or something else entirely, and thought you might have an insight.
(I know YT comment section isn't the best place for this, especially relying on the patchy notifications, so if by chance you do reply and i miss it, I'll give a pre-emptive thank you now)
Had goosebumps during the entire episode.
Almost a repeat of Af447.
Whatever said and done,kudos to the pilots on recovering almost an impossible scenario!
Airbuses and their bloody autotrim.
The scenario that they caused by themselves just because didn't folow the procedures and was not trained enoght.
@@seth1422boeing 737max and their bloody one sensor and MCAS
It's a comedy/thriller.
I can't believe they recovered! I thought for sure it was going to end with a dive into the ground. Major props to these pilots.
I agree. The pilots did a great job considering the situation.
@@makeithappen1598 what? Rather, they just had a tremendous amount of luck...
realizing the trim issue while being in distress thinking the controlls weren't working probably suggest they were able to look outside the box, i've seen too many crash videos to know that a lot of pilots get stuck in tunnell vision and bias sometimes not being able to see simple things infront of them @@przemho0
@@przemho0 yeah, they managed not to kill themselves, damn Russian ignorance for procedures...
They pilots literally went out of their way to crash the aircraft but somehow it didn’t happen
Wow, thank you very much, the story was conveyed in a really exciting manner! I felt relief when heard that they managed to land successfully, I expected them to crash. It is astonishing how much effort is invested into these videos!
Damn, the quality of the episodes is very clearly improving every time!
Yep! That’s what we are trying to do! Glad it’s showing.
Looking through the comments, it's so cool how much you interact with the community! I'm always nervous about flying after watching these videos, but I'm also always glad they come to such an in-depth dissection of what happened and how to prevent it.
Thank you for your nice words. My goal is to show the in-depth analysis that follows these events and how lessons from previous accidents (like AF447 in this case) help with new incidents.
Every single man and woman in a flight and cabin crew, from attendants to pilots are heroes to me. I am terrified of flying, so I have no idea how you folks do it. Hats off to every single one of you. 😀
I often fly, of course, as a passenger, but I have never gotten used to it lol.
I absolutely despise flying, but have to make a 2 1/2 hour flight every two weeks for work. Never gets better😂
I initially learned to fly in Australia, in the coldest city in Australia but none the less a country where -5deg is cold.
When I moved to Canada I learnt what weather is, how to handle it and how to never muck about with it!
Just fantastic that this video ended with no injuries.
Thrilling episode once again, great job. As someone who has flown S7 many times in the past I hope they have improved and learned from this. Although it's easy to be an armchair pilot, the fact that they did not use the backup speed combined with the long duration until they noticed trim, really paints an unfortunate picture of under-training of this crew!
I discovered your channel a few days ago and I've been mesmerized by all those stories, the way you tell them and the detailed and instructive simulations. This is an amazing channel, please keep up the great work!
I feel like the Normal Law / Alternate Law / Direct Law can create so much confusion about which systems are working and which are not. Pilots need to really know the systems inside and out in order to make sense of them - in a high stress situation, the confusion can easily become overwhelming.
Yes exactly. I feel like airbuses are created by French computer scientists! The problem is that in airbus you are training pilots to be irrelevant which is fine until things go wrong and then they need to be super human. Which is ok until they are inexperienced and tired…
Yeah, there should only be 2 modes, full autopilot where the plane flies itself, and manual mode where you do everything. If the plane ever enters manual mode, it will not switch back to automatic without the pilot's command.
Yes, that means the pilots will need to know how to fly a plane in manual mode. But it's what they've been trained on since day 1 in flight school, so I would expect them to be able to handle it.
A number of crashes have been caused by inexperienced piolts not understanding alternate and Direct law modes and that the flight "joystick" stick can operate different modes (and they are Not force feedback so they don't give any tactile feedback of what the plane is doing and what the other pilot is doing, the similar fly by wire Boeing 777 Dreamliner uses Force Feedback to simulate mechanical feedback you normally get on direct hydraulic controled planes and each stick can be deactivated so piolt can easily move out or deactivate a faulty stick)
Af447 co-piolt was wanting 5% up angle up (due to speed tuped got iced up) but it changed to the mode that just changes it to set a angle an holds when you let go of the stick, so he was constantly telling the plane to goto max angle that alternate law allowed due to the temporarily unreliable speed due to ice but due to putting the plane in a maximum nose up the plane could not go back to normal law and he never told the captain that he was doing this until they were 20seconds from hitting the water (this is why on most airlines now you can be fired for using avg mode on the sticks and must make sure you taken control prirorty when your taking control, as captain actions was been countered by co-piolt due to the plane on Af447 using avg mode between the 2 sticks)
@@Julia-nl3gq even a layman can evaluate a Rube Goldberg machine as being prone to human error.
@@leexgx The only safe way to fly an airbus, is for one pilot to take care of the flying while the other is monitoring the instruments and giving verbal communications when required. Switching the control sticks to priority takes time and is confusing. If one pilot (normally the captain) needs to take control, he simply needs to instruct the other to release his sidestick and not use any other inputs.
Perhaps the one exception in difficult conditions, is the pilot monitoring to take care of the throttles and trim, but everything needs to be constantly verbalised.
One major problem with Airbus, is pilots loosing their skills of manual flying. One airline that I am connected with, insists that one short flight every week is flown entirely manually. This is logged and if for any reason missed, has to be explained to the chief pilot. If the crew are regularly flying long haul, they fly manually during the first and final hour of the flight. Needless to say, instrument landing is allowed if the weather is poor.
Largely due to the skills of their pilots, the airline has not had a crash or incident involving injury in more then 55 years.
Never heard much about this incident myself, but this was very well explained!
No, the report is only out in Russian.
@@MentourPiloti heard atc record and read finale report. Chills was all over my body.

Everytime you say the word "stabilized" I can't help but giggle. Your accent is the best.

Wow, I didn't actually think they were going to survive this... Great video, as always. I especially like the fact that you expain what's happening in a way that I (as a non pilot) can understand and follow the chain of events leading to a certain outcome. Your videos surely have shown me that there is A LOT more to piloting an aircraft that just pushing around a stick a little :)
Especially when he said “final dive”!
I wonder if real pilots undergo some kind of training that includes learning about past catastrophes. I've watched some episodes on TH-cam here and there, and even I know about the pitot tubes (whatever they're called). There was at least another accident caused by a problem with those, in South America, I think. The pilots could not tell the speed of the plane. Anyway, I hope actual pilots learn about past accidents, it would definitely help them.
very nicely told story, half the video i was like, ok they won't make it, this it it ! What a relief to see they managed to stabilize back the plane
Yep, this was a crazy story with a happy ending - The best kind of story!
I think the plane managed to stabilise itself despite the pilots!
Omg 😢 that was INTENSE. I’d bet those passengers have an incredible new perspective on their lives. Staring certain death in the face, and then finding yourself walking off the plane safely on the ground 🙌
Perhaps to never step on a plane ever again, perhaps pilots too quit their jobs right after they landed
I fly a lot, as a passenger… this is great content but holy hell it’s scaring the crap out of me. I’m just glad you speak about changes made after these accidents.
I wonder how the passengers felt after spending another 4.5 hours in the air after that!
Yeah, I was thinking that to. Hopefully they didn’t really understand how close they were to meet their maker..
@@MentourPilot if I experienced more than 90 degrees roll in an airliner, I'd be pretty confident it was a near death experience.
@@EviGL since you can neither see outside far enough nor have flight displays available a passnger it is quite possible you wouldnt even notice as passenger..

Glad you like them! My team will love to hear you thought so!
I'm glad everyone was safe after the emergency. I think these "near miss" events are really important. Thank you for sharing it.
Hello sir, thanks for this " danger in the Sky" I knew nothing about. Glad to hear Airbus developped a backup system regarding airspeed.
As somewhat of an air crash investigation nut, but not a pilot, it was hard for me to describe why I feel that AB pilots have worse outcomes when they're called to actually fly the plane. This video does a great job even for a nonpilot like myself to shed light on the factors that play into that. Thanks @MentorPilot!
This was very well explained! It must have been a _chilling_ experience for all those involved, especially with so many issues like the stall and the dive. Glad to see them safe in the end! Great research done by your team, keep it up!
😂😂 Thank you for watching.
Oh no, I spoiled the video for myself. I was concerned for them since I hadn't heard "in latter interviews, the captain said..." at all
Thank-you for all your aviation videos. 50 years ago I was an RAF cadet and although I flew props and gliders as a cadet, my eyesight disqualified me as a full-time jet pilot. I am now a retired engineer and have both worked in aircraft manufacture and been a frequent flyer. Your technical detail is always fascinating.
I couldn’t imagine that they’ve actually made it safely to the ground. What an incredible, indestructible bird, and one hell of a Hollywood-class nerve wrecking episode!
Indeed!
The unending cycle of dives must have been terrifying to experience. I was horrified when you mentioned the switch from alternate law to direct law and vice versa, and the effect it had on the plane. If the Auto-trim had not been noticed and corrected, this would have been a disaster. Thank God it ended the way he did! Amazing episode once again Peter. Always a pleasure!
Wow I'm from Russia and I never heard of this incident! Great video and kudos to everyone who helped you with report translation. S7 is pretty good airline for russian airlines, so the whole video I tried to believe that they'll make it. Glad that they did.

Wow, thanks!
This might have been a more terrifying situation for the passengers, and crew, than most actual crashes. I felt so bad for the passengers during the rollercoaster oscillations.
Many of them must have soiled their undergarments.
Yeah, in many crashes you probably don't even notice it for quite a long time if the pilots don't tell you
Amazing and by your language, I was expecting a crash at the end. Instead, they calmed down during that 2-hour alternative landing flight and survived. It was a fabulous story for pilots or crazy people like ME who are simply interested. (I will sail or walk hereafter.) The lead author is VERY good! Sell this for a movie script!!!
It could've been frustrating to listen to what, and when the pilots did this or that, but you're very good at explaining, and making most of their actions understandable.
Thank you!
But the remarkable thing is how many mistakes they made that were not understandable. This is unusual, most of these incidents involve little to no pilot error beyond what is inevitable when faced with a selection of bad choices. Here there were many good potential choices which could have prevented or ended the upset at multiple points.
I find your videos incredibly relaxing, it’s like every time I turn on a Mentour video, I feel like all my problems fly away. Your videos are really enjoyable and informative, thanks for making everyone’s days a bit better.

@@MentourPilot It shows, great episode MP!
This video was thrilling and frightening as well. Thank you Petr for your in depth knowledge and real life explanations taking place. My 20 year old is preparing for her first solo in about three weeks. I pray in her future career she doesn’t experience anything such as this.
Don’t worry about your daughter- as long as she has a great attitude and a willingness to learn : a strong aircraft knowledge and practical aviation( what used to be called “stick and rudder” skills) and an ability to think laterally and stay calm under pressure but still Follow procedures, practice great CRM then She would deal with the situation like this well - look at Petter who present this channel you can see how he would be in a similar situation.
Unreliable airspeed is not really a problem. Once upon a time I was a baby pilot and my Flying Instructor told me to set a power of 80%, select an attitude of about 15 degrees nose up and Trim (manually), without looking at the ASI... This configuration gave around 180 knots in the climb (some of you may know the aircraft in question?). Power Attitude Trim (PAT). Thereafter, every aircraft I flew, I nailed and memorised the PAT numbers for climb, descent, turbulence, endurance or level flight into my mindbox. The modern aviation world is full of helpful software and systems but PAT awareness would solve many of the issues I see in this technological world. My father was an ex Bomber Command Aviator and his baby pilot was the flying instructor that gave me that advice about PAT.
I was holding my breath, waiting for that crash. That they flew another 4.5 hours before landing is a miracle. That none of the passengers was injured is the icing on top. But I can only imagine the terror they must have felt during those hellish minutes. Thanks Petter for another amazing video.
great pun!
Nobody was injured because they don’t get paid 20k for being sick and getting a headache like in the US. If this happened in the United States they would have had 100+ injuries.
...you mean because litigation? That was a very cryptic comment you made.
As soon as Petter said "he turned on the window heating" I knew what was gonna happen. After watcjing hours of his videos I've learned quite a bit anout aviation it seems. Great video as always, thanks Petter!
I rarely become so engaged with a story but this one had my heart racing and a huge relief that they actually managed to regain their faculties and control.
I couldn't fathom sitting there for 2.5 more hours as a passenger while having no idea what caused all of that and if it could happen again. That had to be such a high stress load.
I was always a nervous flier, but since I was diagnosed with panic attacks I really hate flying. But interestingly I love watching Your videos. As many mentioned before, Your videos and content are top-notch quality. Also, I really like You as a person and I like Your personality. Many thanks for everything and kindest regards

C'mon Petter, -12С in Siberia is almost summertime weather 😊. I am saying it as a person who managed to survive a 15 minute fast walk at -50C at 4am. And despite the fact that I was quite accustomed to temperatures like -30C or even -40C that experience was really special. I knew if I stop or fall, I will freeze there to death.

Passengers must have been losing it and puking.
When you mentioned the pitot tubes, I instantly thought about AF447 and was like "Not again"..Not very far from that outcome either. Crazy how much that airframe withstood.
As UK ground crew, this one is a little close to home. We’re entering our winter season and that means a lot of winter operations for us. De-icing an aircraft is fun, but also a very serious responsibility. Gotta admit I prefer to de-ice Airbus planes. Oh how many times I’ve been on a ground vehicle like that.
It’s fascinating to see it from the perspective of a pilot-and the lack of pushback truck explains why ground crew never spotted the ice on the pitot tubes and AoA sensors. Thanks for the high quality video and information about this incident.
the ice did not form on the pitot tubes. When the pilots turned on all the anti-icing systems, the snow and ice from the heated glass melted down and immediately froze, forming small ice streams.
These thin streams of frozen water became the center of icing, the ice accumulated on them and blocked the air flow into the pitot tubes, while all the pitot tubes did not freeze, the ice formed in front of them.
Also, this was not the only place where ice formed, if you look at the photo of the plane after landing, you can see that even after 4.5 hours of flight, the plane was full of ice, including on the aerodynamic surfaces
Your production values are always on point.
Thank you! My team and I do our absolute best!
There's 2 reasons that cause aircraft to crash....... either technical issue or pilot error, however...... 99.99% of the time, they can and do fly us around the World and keep us safe.

Except this particular air crew, they were utterly incompetent. But I agree, the other ones are amazing!
As an Indonesian every time I hear about pitot tube problem my memory brings me back to the deadly accident Air Asia flight 8501. I am glad this flight 5220 has a good ending. Thank you for your amazing work with your Mentour Pilot team.
The Air Asia 8501 was perfectly flyable, with a minor ECAM warning. But the captain shut down the computers and that was prohibited during flight. After that they lost situation awareness and could not fly manually.
@@sarkisi And thank god, it didnt even crossed the mind of anyone on 5220, at least they got it right.
@@sarkisi Indeed. Problems with the Pitot Tubes caused a couple of horrible Crashs, the most infamous still is Air France Flight 447. But Air Asia Flight 8501 is not amongst them. It was a Maintenance Issue (a repeating technical failure wasn´t cleared), the Captain who shutted the Computers down in a non-understanding how the System worked and the First Officer, who was the Pilot Flying, who suffered a somatic illusion and made therefore erratic control inputs - and finally the miscommunication between Captain and First Officers. But not a problem with the Pitot Tubes.
It would be a good idea for actual pilots to watch some of these videos. They may learn something and I'd feel even safer flying! Keep up the good work..great channel and content.
A lot of them actually are, I bump into them constantly.
Great to hear! Even the best can still learn something from the mistakes and errors of others. And that's how the industry improves.
Not only that, usually when some shit happens somewhere - after pilots (or technicians depending on who fucked up) gets a heads up. "Look what kind of shit happened there! It can happen to you! Don't do that here!" kinda.
@@MentourPilot I wonder how many potential incidents have been mitigated by pilots watching your videos? More than a few I would wager!
I thought there would be a system for distributing reports on these incidents directly to the pilots of the relevant types?
The production quality keeps improving! This is legit professional documentary work. There HAS to be an award appropriate to this channel which I'm sure Mentour would win!
I totally agree! This channel spoils me for many others! Life lessons, in addition to aviation.
And I thought I had a bad day at work. Having to fly after that...
Luckily no one got hurt after ALL OF THAT! It's insane how much punishment planes can take and still fly. Props to Airbus
What a great look at this incident. Glad to see it turned out okay. Luck was definitely on their side. I can't imagine how difficult it would be to just be calm and analyze the situation while all of this was going on. I suppose that's what training is about. Cheers!
Pretty cool to explore all control modes of the Airbus in one flight. Thank you for excellent narration and visuals, as always!
Yes. But not so cool for everybody on board of this Aircraft.
Please make a video about miracle landing of Volga-Dnepr Airlines Flight 4066.
Shortly after take-off the No. 2 engine of the Antonov An-124 Ruslan operating the flight suffered an uncontained engine failure. Debris from the engine punctured the aircraft's fuselage and wings, affecting power supplies and rendering the ADS-B inoperative. The aircraft's braking system was also affected, as were engines 3 and 4. Communications with air traffic control were also lost.
The plane turned out to be without power, almost all the instruments in the cockpit went out. Engine 2 was lost, Engine 1 was in uncontrolled thrust mode, control problem with engines 3 and 4
The aircraft became almost completely uncontrollable. But the crew managed to land it!!!!
Can you send me the final report to petter@mentourpilot.com
Please share the link here in addition! 🙂
No final report yet
@MentourPilot no final report from the Interstate Aviation Committee yet. But the incedent is well documeted, and has extensive coverage by witnesses reports and even video records. There is even an interview with the commander of this aircraft about the details of the incident. The technical side of the incident has already been published in basic detail, the investigative organization - the West Siberia Investigative Department -was occupied with the question of who is legally to blame for the engine failure.

The first plane I flew on by myself. It was winter 1981, it carried less than 50 people, I felt like I had the L1011 all to myself. We had a beautiful view of Yellowstone and the Tetons.
Peter i love your videos and the way you explain them i used to be scared of flying so much that I didn’t fly more than once a yr but now thanks to you explaining things amd 74gear and captain joe I understand what’s happening most of the time amd fly wayyy more comfortably so thank you for everything you do I really appreciate your work I will be rewatching your videos until you post the next one because everytime I watch them i learn something new from them
That’s great to hear and I think I can speak for all three of us when I say that. 💕
I can't believe these two pilots were trained and tested for this kind of procedure, scored well, and still absolutely panicked and only didn't crash because ATC and the plane doing everything in their power to help them.
Yes, indeed.
That's kinda how it works doesn't it? Everyone is trained to deal with it and yet everyone who crashes did so because they failed. All the training in the world doesn't mean diddly squat unless IT is what comes to your mind in a situation like that.
@@michaelbuckers Well...no. Absolutely not.
Most crashes on this channel happens for severe mechanical circumstances, pilots not knowing what the problem is or just bad piloting.
There was no mechanical circumstance, there was literally a list to follow and one button to push, then to safely go trough the procedure. 90% of this incident is the pilots absolutely panicking for something they were trained to.
Your comment is very disingenous because it implies that training is useless, but its not. A lot of crashes are avoided by competent pilots in this very channel. These two literally ignored any basic point of their training and gave to fear, and the only reason they didn't end in a mountain is because the ATC screamed it at them.
@@CrowMercuryWell to be fair, it wouldn't be much of a video if the unreliable airspeed warnings are dealt with as per the manual and everything proceeded fine after that.
@@duncanhamilton5841 I'm fairly sure that Mentor wouldn't be too sad if no other air incident ever happens, but you have a point.
As this was Russian and I have watched a few of your content about Russian crashes so I was expecting this to have a tragic ending. But thank God! I really felt for that first commander. I can see myself reacting the same way
Great analysis and first time I'd heard about the backup speed/altitude system, airbus created after 447. Seems like a good way to remind pilots of pitch plus power equals performance, sad they didn't follow it.
Oh my goodness, i’ve had sooo many videos of yours in which i hoped for a good outcome. But this one really really was the one i cannot fathom the huge fears everyone on board had & then have to fly for a few more hours even!! I am really really glad they landed safely! Even tho big mistakes were made, the pilots never stopped fighting, flying en they never gave up & that is something i have tremendous respect for! Thank you for another amazing video!
the problem is half the time they were fighting good sense and the safety features.
This is about piloting. If you know the wind, know the plane, you know what thrust you should have. Just keep that, keep level, and you'll get out of it soon enough. Just keep a close eye on the ADI.
This video has the best explanation of the airbus 'laws' I've seen yet - been confused about those for a while and this cleared it right up. Thank you!
Yes.
Given how many Pitot incidents there have been over the years you would think that "Snow" plus "unreliable airspeeds" would automatically mean the pitot tubes have frozen. Given that the engines were working fine you would think that you would set a throttle position and pitch angle for safe flying and that once set a "stall" wasn't possible. Since they knew the airspeed was unreliable it seems crazy to me that they react like this.
Not really. And you've missed a few other factors that could account for that.
@@BigHenFor I mean, that was basically what they were supposed to do based on the memory items, no?
Its pretty simple, other pilots even managed it successfully which lead to that backup airspeed bar that gets briefly mentioned then apparently ignored by these pilots, despite this being exactly the situation it was created for.
They were startled and in panic and forgot how to deal with the upset. Plus, it's russia so I have my doubts about the quality of their pilot training.
Yeah yeah good but they also thought that their wings are also being covered with ice during flying through clouds, so it's completely understandable that they expected wings to lose some of it's lift and be prone to stall
@@johnny_ethlet’s say, there are pilots who do not take their training seriously. Add some complacency and you are full set. I work for S7 and if one wants to be a good pilot, this company gives the means to be.
My favorite of these videos are the ones covering incidents that everyone walks away from and where lessons are learned that increase air safety.
Yet another awesome video! It makes my day when I wake up to a new Mentour Pilot Video. It is also shocking just how many incidents relate to the pitot tubes.
Thank you for those kind words! Yes, the pitot tubes are a weak-spot for sure
11:20 As soon as you said they were leaving the snow on the fuselage, I thought about the possibility of interference with the pitot tubes and/or angle of attack vanes.
