What happens to an aircraft that climbs above its maximum altitude and how do pilots deal with a high and low-speed stall?
Todays episode is PACKED with useful aviation information so make sure you watch the WHOLE episode to the end and ask your questions afterwards.
I have also include undisputed proof that my dog is, in fact, alive but you will have to wait until the VERY end to see it.

Please tell me the context of the dog reference
@@stephenclark5667 Look closely to the pilot side of the sofa panel. There is a small furry sleeping object called a dog. Don't touch the dog, you may set off the master alarm (loud "RRRRRRRRR" sound, but it may go immediately into an upset condition without prior warning.
I'm pretty sure that's just a hairy squirrel
The dog received enough lessons it could fly a plane
Saqr Almalki It often does, that's why it's so tired...
Please tell me the context of the dog reference
@@stephenclark5667 Hahahahahah, yeah ... you could say that !
The FAA checked and it turns out there’s no law that says that a dog _can’t_ fly a plane

I want this guy to be the pilot on my flight.
I am a Physics teacher in New York and I can't thank you enough for explaining so much of the piloting in Physics terms. The reason why a maneuver is needed is so much more informative than simply what the maneuver is. Your series is wonderful, thanks! I will be playing this one for my students.
So you make lives a living hell for a living. Lol congrats, physics is still the source of my worst nightmares.
damn man you are a physics teacher? smart smart guy
@@lbj2320 no, eventually, by doing nothing else, teachers start to accept what isn't really understandable.
It becomes autosufficient, selfexplanatory, obvious. That's why teachers are so bad at explaining things.
They can't put themselves into a mind that does not understand.
They give explanations that don't fit all (extreme) situations.
That's why Newton got overruled by Einstein, and that's why Einstein's theories last so long.
Those teachers can't think anymore outside of the borders they set themselves into.
A smart guy is someone who can think outside of the borders of his speciality, someone creative.
Teaching and Creativity are antonyms.
The only class where me and my friends actually competed for highest score on tests because the topics were so fun, challenging and fair. I loved physics and I was a jock.

The dog appears to have stalled.
Hahaha!
I guess the dog's nose is down.

Great minds think alike.
Yes, because he exceeded his maximum allowed altitude.
Beyond the fact that you're an extremely smart guy, you're an excellent communicator. love this channel.
Thanks so much
oh yeah, and make me feel better about the safety of flying. Nice!
I figured out why you're such a good communicator: you understand your audience so well, and describe your craft in terms we can best understand. Amazing, educative use of aircraft terminology that everyone from pilot to novice can understand.
Speak to the level of your audience, throw in new words and define them to enhance their learning experience and show off your knowledge. Others have skills we can learn from.
Your copilot seems incapacitated 😁😁
The dogs the pilot since he's on the left. The couch is a plane obviously
😂
😂😂😂😂😂😂😂
He got him high with the weed he’s growing out the back. He should have closed the blinds :)
The dog sleeps in the captain's seat...demoting Mentour to FO...LOL.
I submit to my pets too.
I love how passionate you are about this, makes me feel far more confident about flying, i hope other pilots are this passionate.
I want to fly with that Sullenberger guy who emergency landed on the Hudson River! That dude is a badass! 😀
@Csab Is he? That's too bad, having him as my pilot would be very comforting given his skill level!
You have to be passionate to do this job. You simply cant stay in it for the money.
With all of the schooling and testing and retraining you have to go through, I would say yeah, a vast majority of pilots have to be passionate about flying. Especially when you take into account all of the travel and being away from home involved.
@@ligdeyendama884 No one is a pilot for the money

Never noticed his dog until it stretched lmao
Looks lifeless lol
This is the guy I want sitting in the Captain's seat on my flight.
Either him or Sullenberger!
Really
Agreed. This guy can make a brick fly
I agree with you for his knowledge, but as a passenger, you can't really know how capable and intelligent your captain is, unless you meet with him/her, which is almost impossible.
@@joshglover2370 There are thousands of pilots who know their craft well though, it's just that they don't communicate their knowledge on a social platform.
An awful lot to remember when I'm needed to fly the plane after both pilots have become incapacitated.
That's one thing I don't like about flying. I don't like being in vehicles I don't know how to operate. I can drive a bus and I could at least get a train to stop if something happens to the operator. On a plane, I would be screwed! 😳
Do you pray?😟
Josh Glover to be fair, you can probably make the airplane stop too...
@@audigex Yeah... Probably not safely though! 😅
@@coiledsteel8344 No, I look for solutions that actually work. God is either not there or doesn't care about us. Ever been to a children's cancer ward? I can tell you who hasn't... God! 😠

Dog's in the left seat. She knows what she's doing. I hope.

Okay, you convinced me that pilots deserve their salaries.
It really does take an incredible amount of skill!
@@joshglover2370 not so much skill , more knowledge.
You‘d be surprised how little they make these days.
They’re underpaid and overworked
@@dixie_rekd9601... takes skill to apply knowledge.
Another excellent video man. Thank you for your knowledge sharing. You may have covered this but a question Ive always had as I fly commercial a lot is when coming into land every time no matter the airline a ' ring ring " almost like a phone call happening between what I would guess is 5000 feet and lower on approach. What is this? Ive asked a couple of pilots when exiting aircraft and they act like im crazy lol. And just to be clear this isnt a cell phone type of ring ring before somebody says its people phones ringing lol. Its the same exact ring on all the planes. Thank you in advance to anybody that knows the answer or can post a link here to where hes already explained it.
Is it the call from the cockpit to cabin to verify that the cabin is secure?
Mentour Pilot sorry i wasn’t clear on that either. Nobody is answering a phone or anything including the flight attendants there all seated, it’s different type of ring. It’s almost like reaching a certain altitude it decent it triggers this ring ring. I fly out out Las Vegas Nevada so I always return there. Right on the outer edge of the city there’s a little line of mountain ridges that kind of separate the city from the desert. It’s like clock work every-time I’m returning from the eastern side of the US and we’re getting close to that mountain ridge I hear that RING RING right in the same area. It’s driving me crazy to know what that means lol. I will make it my mission to try to remember to record a whole decent to see if I can capture the sound on video in relation with the outside window view etc
THELIFEOFPRICE maybe it has something to do with the area ur flying over? I have no idea tbh but do u know the answer already? I really want to know now XD
If nobody else hears it around or with you maybe it’s an inner ear or neurological issue that occurs due to pressure changes or some other phenomenon.
Maybe the autopilot disconnect?
The dog became a part of the mentour videos.....
Is it real?
@@robbiebunge859 yes, at some videos it moves..
I mean I’m not complaining
Mally Robots move. Or it could be CGI. Or maybe it is real but has a barbiturate or opiate problem.
Earf is fat. Nice sea gee aye punk ass!
This video just explained why it is so difficult to design and develop an aircraft. On top of that make the aircraft fuel efficient.
Big kudos to the people at Boeing and Airbus.
I'm glad I already researched aerodynamic a long time before I saw this video; It made it so much more interesting when I understood the principles behind what you were talking about! Amazing video, and extremely informative. There are so many more factors that I didn't think of in the particular situations you described. It's so cool that science has brought us to the point we're at and will still continue to push boundaries. Love your channel!!!
Thank you!! I’m glad you say that and that your studies confirm my explanations.
****************************
Are you familiar with the 'Ideal Gas Law', PV = nRT ?
(Pressure X Volume = number of moles X ideal gas constant X temperature)
You began with speaking about air speed and pitot tubes. You mentioned that the pitot tubes measure the number of molecules entering the tube.
Now when you say number of molecules 'n' (number of moles) I.e. the number of moles in the sample of air I immediately questioned that because it doesn't actually measure the number of molecules directly, however, it is relative to it (indirectly)...
n in air = mass / Molar Mass
n in air = approx 28.96 g/mol
@@ajcook7777 Pitot tubes do NOT count or measure air molecules. It measures the pressure of the incoming air and displays it as indicated airspeed. But since air density decreases as altitude increases it requires a higher TRUE airspeed to equal that pressure.
@@jvabsher I know it doesn't measure the amount of moles of air entering the tube, however, if the altitude stayed constant it could be somewhat proportional...
Sir, Which is good Airbus or Boeing in terms of modern technology?
Fun fact, if you look on the top of the engines you can sometimes see transonic standing waves. The 747 was quite common to see this but you can sometimes see it on other engines. Needs to be sunny and you need to be really in a good jetstream. Its like a line coming straight up from the engine right on the top of the curve of the nacelle - its very small but if you know where to look you can see it.
One of your best videos. Thank you for a excellent explanation and I hope you will keep making more technical and thorough videos like this! And the dog is just so cute. Having him appear in the videos just brings another great flavour to it.
New Mentour mascot !?
She has always been the Mentour Maskot. :)
Thank you!
Also from me, many thanks for this video, I thoroughly enjoyed this one. I'm not an ATPL and have never flown a commercial jet. Still I have a quick question on over-speed/stall-speed at cruising altitudes in A/P config with Mach number speed set (ie. 0.77). I was wondering: Is it true that while flying in such a config, an over-speed/stall-speed situation should never occur as the Mach number is always relative to altitude?
Thx mate, keep the vids going? Love them!

Paula Zemeckis Dude, that's my GF.... Believe me, nothing gross there...
You know how I know your videos are good? Because I always watch your videos and I’m not even a pilot; don’t even aspire to be one. You explain stuff so well that this “pilot stuff” is intriguing. I don’t even watch videos of my own career field.
Wished you were my physics teacher!! You explain everything in a way that it's easy to understand (at least, it is for me😉)
Your dog is so cute, had a poodle myself. Love them!😍
They are adorable
Sounds like you had a math teacher as a physics teacher. No body can turn a simple basic concept into an absurdly complex ordeal like a math teacher.
Well, except his math is a bit out.... ie if the engines stall at 38,000 feet and you drop at 1:17 then you have more than 60nautical miles, basic theory says 122 miles, however this ratio increases as the speed reduces, which by the way won't be a massive amount even due to the increased density at lower levels... I would like to see the equations for this..
Correct but you forget that we don't want to maximise the glide, unless we are out over the sea. We want to choose something that is comfortably in range and enables us to extend flaps and gear as well. We generally calculate on 3 times our altitude for descend calculations + 1 nm fro each 10kt to decelerate down to 200kt.
Thats a toy stuff. Not real poodle.
As airforceproud95 would say, the plane would “eat shit”.
I don’t know how this man explains things so well, but I sure love it
It is called buffet margin by my airline. We always want enough buffet margin so if we hit a little turbulence we would not stall or overspeed. I flew the DC-10-10 and the DC-10-30 The -10 had much smaller engines but the same wing. We could climb the -10 and it would just stop going up due to not enough power but we were still well below the max altitude for the weight with plenty of buffet margin. The -30 had much bigger engines and we had the power to climb to an altitude that would put us in danger of not having enough buffet margin. I also flew the 767-200, -300 and the 767-200. The 757 has the power to climb too high for the weight. The 767 -200 does not have enough power to fly too high for the weight.
Your videos are interesting but it looks like your "vicious killer" dog is bored.
I'm not a pilot. I'm not really sure how I stumbled on to your videos, but I've found them to be very interesting and educational.
it's simple what goes up must come down🤣🤣🤣
You are a pilot and and you are sure
@@TimPerfetto he is sure even though he has never flown a plane that has shitty controls that cannot control the plane under all loading conditions like that Russian Passenger liner had so he thinks he can handle a plane that can go straight up till it stalls stopping it from going straight up he gets a gold star for effort
@@raven4k998 He has flown every plane and all can control the plane under zero loading conditions
This is my new favorite binge channel. As a mech engineer, I loved Aerodynamics. This is so interesting to watch, not just this video, but all of them! Great job!
Think the dog was at snooze altitude.
I have no intention to become a pilot anytime soon but I still find all of these videos really interesting and informative.
Great to hear! Feel free to spread the word.
Same here ... don't laugh but I like to play flight simulator games (X-Plane 11) and these videos are very helpful in getting a better understanding of aviation concepts.
Sums me up exactly also.
me as well
I took some ground education in college but realized I have Bold Pilot Syndrome (you know, "there are old pilots, and bold pilots, but no old bold pilots"?) this channel gives me the aviation info fix I really need. -Patrean Brian
As an amature sport pilot, I learned alot from this. Especially the difference we deal with between light and jet aircraft. Well done.

This is a nice video!
I’m so happy you liked it.

The 757 I was on flew at 41,000 feet to stay on top of a storm. It was cool looking at the thunder storm under the plane from the window. Once we were past the storm the captain said we are going back down to 35,000 feet.
Dog: what the heck is my master rambling about.....
In dog translation its all a relaxing "blah blah blah.... blah blah". The only sound dogs register when they are deep asleep are the words "wanna go out" and the sound of a packaging opening! I can't open anything packed in plastic without having my dog into high alert mode.
I dunno, but he's lowering the oxygen level.

@@AngryHybridApe Very true! When someone rings the bell my dog goes "What??? What the hell is going on here??? Whos there??? Im ready!!!!"
I seriously didn’t know flying a plane was so complicated. I seriously thought it was just a case of Taking off, engaging autopilot then landing.
Serious respect to all the Captains and First officers. Got more brains than i have.
My wife has run payrolls for 47 years, starting long before the days of computers.
If you had a problem with your pay, she would look at the whole year, since figures are accumulative. This means that all the figures for month 5 are your totals to month 5 minus your totals to month 4.
Since computerization, many staff do not fully understand fully how the system operates, and when a mistake occurs, their attempts to correct it simply add further errors, rather than address the original problem.
Sadly automation if flying has created a similar situation, leaving pilots hazy about the root cause of the situation they are in.
While a mistake in you salary may involve waiting for another paycheck, a similar mistake by pilots may mean that you never need another paycheck.
One major European airline still insist that pilots regularly fly manually and keep their knowledge active. As a result, they have not had a crash or persons injured in more than 50 years. Although their safety record is better than Qantas, they feel that it is wrong to advertise safety.
I wonder whether you can work out which airline.??? One obvious clue is that you wont find them in any air crash videos. LOL.
you cant be that outta that loop...
wilsjane which airline are you talking about exactly? Since qantas took the throne every year...
+Ziran Yang. Aer Lingus. They are the unsung heroes of the airline industry, with neither a crash or serious injury in more than 50 years.
Injury figures can be very misleading, since a twisted ankle while boarding, or even a broken finger nail closing the overhead lockers gets included in the statistics. (Many of these claims are false)
Serious injury is where someone is kept in the hospital ward after treatment.
It is therefore the true figure.
I'm not an (airline) pilot, so tale this with a grain (or more) of salt, but when everything goes according to plan it may actually work the way you have believed.
Somebody put it along the lines of aircrew earning their salaries for being ready to save the day when stuff doesn't work.
There are plenty of incidents where this has been proven true . . .
What is your worst experience or emergency that you have encountered in the cockpit? What was the worst situation you have been in? Just curious. And how did you fix it? We all look up to you. You do an absolutely fantastic job with the channel! Thanks from Cleveland, Ohio!!
They can't say because company Rules , I ask to a pilot one time and he can't say and explained why not.
@@lucas3087 surely if it wasnt the companys fault and it went well they SHOULD be saying it to promote how safe the company trains their pilots
OK, good video, but...you didn't explain how MH370 flew into space and left our solar system...

I'm as well looking for answers to find some explanations about the creepy and unnatural dissaperance of one of the most technologically advanced plane.

@Devbo Slice Cheryl Ladd was hot. No wonder he went for her!
@@victorcrowley8417 the plane was probably hijacked by some people in the cabin and esentially continued with the flight changing flight paths over the Peninsula and with the fuel excaustion they crashed in the sea next to the island of Reunion.
Chad Portenga Good movie
The SR-71 which operated at around 100000 feet (3X higher than airlines fly) the stall speed and never exceed speed were about 5 knots apart. It was a very tricky plane to fly.
The SR71 did not climb to 100k. More like 85k. And the plane with the 5kt difference in speed would have been the U2, not the SR71.
I would think that the very thin air that high up would make flying very difficult and dangerous!
I didnt find it too hard....
Got to talk to a U-2 pilot some time ago and that plane, at altitude, had a VERY narrow flight envelope. The U-2 pilot said, if you turned at max altitude, your inner wing could be at a low-speed stall while your outer wing would be at a high-speed stall. Talk about walking on the edge of a razor!
Plane: stalls.
Captain: ahh crap idk what to do.
Co pilot: well let me bing up this one youtube video.
I bet you fly like you talk, smooth and relaxed, your dog was in pure peace.
The dog is like "yadda yadda I've heard this *so* many times before" :-)
Excellent video, thanks a lot.
After this video and others I think I got it when they say "Fly the plane." Keep the plane from stalling no matter what. By doing so the aerodynamic surfaces allow you to continue to control the plane. It seems that "nose down" is a common way to avoid going in to a stall. Thank you for this video.
I got half way through the video before I noticed the dog.

Can you please demonstrate high and low speed stalls in a simulator ?
Very informative. This level of knowledge should be with every pilot and sort of scary that the Air France pilots did not know about this.
I think they did; but the younger pilot went into panic mode. He was using his controls to go up while Robert (the more experienced FO) was trying to travel down; and so they cancelled each other out.
Their situation was very difficult since they lost airspeed due to frozen pitot tube the inexperienced pilot got himself into trouble as he was not sure what thrust to put on as well as bringing the aircraft angle up
Yep I saw a documentary on it and one of the pilots basically froze and obviously panicked. Really the Captain should have just ripped him out the seat and sent him to the back of the plane.
@@johntormey8169 should have turned the Pitot hear on.
I had the pleasure of riding in a 727 airliner that flew to the edge of the envelope. We were late for getting to Washington National, which closes down at night for noise reduction to nearby neighborhoods. At cruising altitude, the captain announced that we would be traveling at Mach 0.9, so please excuse the increased the airflow noise. We made it in time to land at the airport before shutdown.
I've read that 727s, especially unloaded, were real rocketships. Airlines don't go for that anymore because of the crazy high fuel consumption.
@@hubbsllc Yes, they were gas guzzlers. But, better than DC-9s of the time.
The 757 is the replacement also very fast
@@flopo3044 I think the 737 replaced the 727 as well as the 717. I have been in a 757. Nice plane.

What percentage of your pilot money do you make off of your you-tube videos? Are you a pilot that makes videos or a you-tube star that also flies planes?
so here is a question:
what's the difference between:
* TAS (True Airspeed)
* IAS (Indicated Airspeed)
* CAS (Callibrated Airspeed)
* GS (Ground Speed)
Some are more obvious than others, but I never understood the difference between calibrated and indicated.
The way I understand is it IAS is the speed relative to the outside air movement and pressure. So basically proportional to the back pressure in the pitot tubes.
TAS is the physical distance you move in standing air divided by the time it takes.
GS is the physical distance you move on the ground divided by the time it takes.
wikipedia says:
Calibrated airspeed (CAS) is the IAS corrected for instrument and position error. what does that mean? Shouldn't instruments (like the pitot tubes) be giving the correct readings (pressure) in the first place? And if you don't know the error (because the measurements you're getting are imprecise to begin with), how do you correct for it? And if you do know the error, why is that not factored into the measurement to begin with?
Try this. Indicated Airspeed (IAS) is whatever you see on the airspeed indicator. It's also the speed of the "relative wind" that factors into lift and drag.
Calibrated Airspeed (CAS) is IAS corrected for "position errors" that occur in measurement of pitot and static pressure as a result of normal changes in aircraft attitude (like nose up at low speed and less so at cruise).
True Airspeed (TAS) is IAS corrected for density of the air mass through which the airplane is actually flying. The atmosphere becomes less dense as altitude increases. Less dense air develops less pressure in the pitot tubes. As the airplane climbs to higher density altitudes, IAS will lag behind the actual "True" speed in the airmass by about 2% per 1,000 feet.
IAS is what you fly the airplane by. CAS is an engineering measurement of no use whatever to the pjlot (outside of oral and written exams). TAS is the actual speed in tbe airmass, which you'll use along with wind direction and velocity to calculate groundspeed, ETA, and range.
That’s so damn interesting and cool !!!! Master pilot level !
It should not be masters level. All pilots who you entrust your life to should know their job.
Sadly, their are quite a few exceptions.
Piolet level 99999
15:30 "The clicking clock will tell you that you are cleaning a laterine" .....AUTO GENRERATED ENGLISH CAPTION :-p :-p
Jajajjajajajajjajq
And that's how I put my dog to sleep!
Like they say: speed is life, altitude is life insurance.
and if you buy too much insurance it might ruin your life lol
PCanas makes sense
I actually reached the “coffin corner” in X-Plane Flight Simulator 11 in a Boeing 737 at around 48,000 feet, and at about 380 knots (Sorry, I could not recall it. Sorry about that.) TAS.
When I was a kid I thought if the pilot forgot to pitch down to account for the curvature of Earth the plane could fly off the Earth and be lost for good.
I'd love to have you as my flight instructor
That is possible.
Honestly that would be pretty awesome; Mentour Pilot i like that reply.
it would require him applying for rya--*cough* your "mystery airline".
maybe he is kinda an a** as instructor? *ROFL :D - because he seems to be a very good one, those are mostly strikt ;)
id love to have him as my groundschool instructor
That Air France 447 was able to happen is absolutely terrifying. Its still difficult to understand how pilots can get so confused so easily.
I can see that you are new to the human race.
Pilots get confused much like humans get confused doing simple tasks like structuring a sentence. It’s generally ez but yet we fail at it, so ease up and realize mistakes happen. Ever planned a pregnancy?
@@downtownbillyandthenewjivefive One pilot was pulling back on the stick and the other pushing forward on the stick in which case they cancel each other out. Two professional, trained civil aviators took a perfectly good, functioning, working plane and crashed it because one pilot didn't know what the other was doing even though they're only 3 feet apart from one another. He's damn right that's scary.
@@duramaxdad This was one of the stupidest mistakes ever made. It's like a guy in the documentary said "All they had to do was 'nothing' and everything would have been fine. When you have pilots that aren't trained in the basics of flying, you don't have pilots anymore, you have passengers."
@@jamesstreet228 That's insane.
This was one of the reasons why the U2 Spy plane was 'difficult' to fly when it was at extreme altitude, it would only be a few knots away from high and low speed stall, so needed to be monitored closely when at 70,000 ft.
Thank you.... The High Speed Stall was something new to me - albeit making full sense! I would sommise flying into a Jetstream Tailwind would be a cause of this.
More jet stream headwind actually. A sudden increase in headwind will increase the indicated airspeed
yeah, I lost an aicraft due to that... (on FSX). Actually becuz it has "updated" wheather and BAM!!! 80kts Wind on 0° aaand overstressed. I had no Chance ... actually -.- (Aerosoft Airbus A320 -> CI 30 ~ .76 Mach autothrottle.. @ 36000ft). Place -> Croatian Coast :/
I would think a tailwind would cause a stall flying on the edge of a stall too. Less air moving front to back over the wings. Of course I assume I'm wrong because you know your stuff. Is the dog a teenager?
Let me tell you in 20 seconds so you dont have to watch the whole video:
Basically there is not enough air that high in the air and the engines of an airplane need air to work thats it and there also some aerodinamics.
When an aircraft climb too high it becomes a Space Shuttle.
Tower this is delta alpha lima... we have the international space station in sight, the temperature here is exceeding 2000 Celsius. SOS
😅😂🤣😁
A U2 spy plane at 75,000 feet has an air spped of 110 knots and flies within 2-3 knots of its stall speed, max height was dependant on what pilot was flying and what he had for breakfast...
Very cool!
I'm surprised it didn't get a mention on this topic. That aircraft is designed with an intended flight envelope that crawls all the way into that coffin corner right up to the cusp. Kind of crazy what they did, until they tried another strategy with the SR-71.
I read that the U2 was always hovering between stall speed and ripping the wings off with only about 20 kts to play with.
Yes overspeed was at 130 knots or so, at max height if the pilot was to lurch forward in the cockpitmthat in itself could cause a stall, crazy really for that age of development
@@pauljs75 the sr-71 is an amazing aircraft within itself, those j-58 engines becoming more efficent at higher speeds just baffles me, only until recent years are passenger aircraft engines following the high bypass design, i am suprised that rolls royce or general electric havent tried to use some of the tech to make a viable high altitude aircraft engine for commercial use, that would be immense and potentially cheaper than long haul flights with current plane models...
I understand but aren't you traveling a greater distance on the aerial sphere? The greater the distance from the center of the earth the greater volume and the surface distances are.
Very good video. Please do a video on steep climb and risk of stall.
So I'm quite a nervous flyer. Having watched nearly all of your videos I feel more confident that there is no need to be nervous at all and in fact I could probably fly the plane myself at this point!
The Dragon Lady (U-2) is the Queen of flying in the coffin corner. :)
Right Steven. Years ago I read a book that had an interview with a U2 pilot that said he had to fly within 5 Knots if operating @ maximum altitude.
The other interesting part is he said the plane was very sensitive to control input at high altitude.
Dog-"Oh geez is he going to give the aerodynamics speech again?"
Excellent videos! You are not only a first class pilot but also have profound teaching abilities and talent! bravos!
Mentour pilot: this is the reason why air crafts are seen as the fastest mode of transport right now.
Russia: Hold my Soyuz.
Elon: Hold my BFR.
I have learned more from your experiences and explanations than from any text I have read
Kevin Collins agreed!
I have a terrible fear of aircraft but because of your videos.... I will be taking a flight very soon all by myself. I'm still very much afraid but you have shown me how skilled, professional, and dedicated the entire aircraft crew is. If anything was to happen (as my fear keeps telling me) I know that I will have the very best of the best watching my back. Thank you Sir.
I’m so happy that I have managed to alleviate some of your fears. Let me know if there is anything else I can do,
Just keep making these videos! Even though they are filled with technical items, you keep it easy enough for someone like me to follow and understand :-) Soon, in two weeks I will be flying from my home in Ireland all the way to Japan all by myself. I am still afraid but now I understand how much true effort goes into designing safe aircraft and how much a person has to master to even step a toe inside the cockpit. I feel a lot better now because of you (and I get to see Japan as well lol) so thank you very very much Sir.

After your first flight you will love flying. You will wonder why you didnt fly sooner. Enjoy the ride, and enjoy your trip to Japan! Be sure to post back here and let us know how your trip was.
Typically one’s fear of flying commercial comes from the knowledge that one is not in control, seated in the cabin for the ride. But how often does the typical driver check their tires, windshield wipers, or brakes before jumping into their car and zooming off? Hardly ever? Commercial pilots do safety walk-arounds every flight. Since 1923, commercial aviation accidents have accounted for 57,563 deaths worldwide. On the other hand, automobile accidents in the United states accounted for 37,461 fatalities in 2016 alone. Put another way, one’s chances of dying in a plane accident are somewhere between being killed by a firearm and electrocuted; considering the safety record of commercial airliners in 2017, one would have to fly every day for 6,033 years before experiencing an accident in which at least one person was killed.
That being stated, some aircraft are inherently more dangerous than others. For example, The ATR 72’s performance in icing conditions has a lot to be desired; some would consider it a serious design flaw, icing conditions accounting for 5 of 11 hull losses. Let me put it this way. If your meddling mother-in-law won’t accept your 1972 Ford Pinto with Firestone 500 radial tires as a gift, offer her some free tickets on an ATR instead.
@@SlipFitGarage, It was....... AMASING! So beautiful and the people so very friendly! I started in Tokyo and went up to Chitose in the North. Everywhere I went it was absolutely clean and everyone was extremely polite and helpful. Everyone tried their best to make me as comfortable and welcomed as they could. In Chitose, an elderly couple even insisted that I stay at their home instead of a hotel. We could only speak with each other thru google translate but even still it never felt like a bother with them. I cannot believe how much of my life I wasted, and experience lost all because I was so very afraid. I'm still a bit of a baby (especially when we experienced turbulence) but the majority of the flight was so very smooth that I actually slept most of it away lol. It will be quite the long time before I can ever afford to go on another trip but I have already begun to start my savings. I do not know where I will go next, perhaps to America and see the Statue of Liberty in New York state or go on a ride on a paddle boat in Tennessee state. The sky is the limit now :-) I will never allow fear to rule my life again.
...and all of this is thanks to you Mentour Pilot!
Red pillow on the left, green on the right side. :) :) Fantastic! :)
And a zonked out dog between them.
I’m confident enough by watching this I can fly a plane .
dog slept through the whole presentation.thank you sir for the info.
I'm studying aviation engineering and your videos are really helpful!!
Please don't design any planes I might fly on
he explain more technical stuff than Cap. Joe
I like it.
You must be super sober to do all these balancing acts at once. Well done Sir.
Computers take care of it for you.
I was on a Commercial Jet flight about 30-45 minutes from landing in San Diego, CA....We heard a loud BOOM, the plane started having a VERY VIGOROUS VIBRATION, and then the plane started pointing down and leaning to the right....It seemed to take a long time for the plane to "almost" get back level and it did it all over again!!! Pointing and angling down and to the right--while VIBRATING VERY VIGOROUS!.....The pilot said we dropped 10,000 feet (it felt like 50,000 feet!!!) . What do you think REALLY happened??
Very interesting. I really appreciate your videos.
Awesome video Petter, I learned a lot!!
How it just came up 3 minutes ago

The 3 Golden Rules: 1. Pick a great airline. 2. Fly over land as much as possible. 3. Break up your trip.
It would have been interesting if you had commented how some military airplanes are able to fly at much higher altitudes and speeds.
Also, a question: If this kind of stall happens, do you need to write some kind of report about it afterwards, and if yes, what kind of report?
They have different shaped wings. Instead of a high camber on the top surface they are kind of diamond shaped with sharp edges. So they perform differently and they are designed to have a permanent supersonic shock wave emanating from the corners of the diamond. So they don't high speed stall ... well technically they do but the separation of the airflow is deliberate and you don't get the same sort of loss of lift. So flying higher they can now break the sound barrier and fly at much greater True Air Speeds. You basically eliminate the high speed stall aerodynamically, and now its just a question of how much power the engines have against the massive amount of drag being created that defines your top speed.
Great video as usual. Can yo explain the differences between a fighter jet pilot vs a passenger jet pilot, as in difficulty, qualifications, advantages and disadvantages, etc. I find your teaching style very easy to follow. Just enough words and their proper use, without stressing out a learner. You put your learners at ease and keep the topic so interesting, that one just yearns to learn more, One can sense that you really love your profession and would make a great instructor for the pilots of the future.
I would have to find a fighter pilot to interview for that. Great idea.
Ha! Crossing the pond we had fighter jocks race past us in a show of typical bravado. When they called us on radio (we were flying a multi-engine military aircraft) we'd say that during their "show" we had got up, used the potty, taken a walk, and fixed a sandwich, which they can't do!
Say you take a group of 100 intelligent people who all want to be fighter pilots and they do their best to get there and work hard, 1 or 2 might make the grade.
If the same group of people set their sights on becoming an airline pilot and did everything to get there and worked hard, 50 or 60 might make it.
That should give you an idea of the difference between making it to the cockpit of a fighter jet and making it to the cockpit of an airliner.
@@schumifan78 your opinion is as arrogant as it can be. That's the opinion of only one dumb person like you
Flying fighter jets would be easier than commercial because fighters have such a high engine power to weight ratio. Low speed stall? Add power they will pull out of anything even vertically. Very aerobatic totally different don't have to worry too much about stalling so they can focus more on combat. But now some idiot will try to prove me wrong and I'm sure it's going to be an American because they are so stupid
You make things sound so simple, but it isn't. At 40,000 feet, you have explained that it becomes a "balancing act" at times when air density changes, or storms cause lower air pressure, and strange atmospheric behaviour. Back in 1969, the Concorde was developed. Concorde flew at a higher altitude, and (yet) had similar jet engines. Concorde flew at Mach 2. So, I am asking: What was so special?? I am not sure if you have ever spoken about the physics of Concorde, and it would be extremely interesting to hear your "take" on Concorde, and the reasons why this plane could do so much, at a time when planes had nowhere near the technology of today! Please consider talking about Concorde. Great to sit in an Armchair, and learn so much. Thanks.
interesting tidbit i saw on YT: a pilot attacked a german bomber formation, diving thru it. when he attempted roll out he had no controls. when he was nearly on the deck control returned and he pulled out at grass-cutting altitude. engineers later thought he'd entered near or at supersonic speed, as the sonic pressure wave ahead of his wings and stabilizers swept the air above/under and around his control surfaces so he couldn't maneuver. the higher air pressure at low altitude dampened the effect, such that he could regain control. i immediately thought of this during this vid. excellent as usual!
Extremely interesting. Thank you!!

Air Transat Flight 236 is the best example of an aircraft's gliding capability. How was Concorde able to fly at 60,000 feet?
Thanks for the education. This "coffin corner" thing seems surprisingly counter-intuitive to me, but well explained. It sounds like you guys are skating on ice up there but nice to see you know what you are doing:)
No wonder why i keep on stalling on infinite flight.
Nice graphic...but planes fly over a Plane....as any pilot should know, love your work though!
Thank you very much for the interesting information.
