For anyone interested of a case where this was "tested" in an actual flight, have a look at Federal Express Flight 705 in 1994. There was an off-duty second officer (Auburn Calloway) who wanted to commit suicide so his family could get the life insurance payout. But the two pilots managed to stop him. As part of this, one of the pilots ended up putting the plane into a very steep dive. As far as I remember, they went over VD and started experiencing fluttering. Some parts of the wing also broke off. But they managed to keep flying and landed safely.
In an trilingual household like Mentour's, the dogs could also bark in three different languages. In 🇬🇧 bowwow, in 🇪🇸 ¡guau! ¡guau! and in 🇸🇪 vovve vovve! 🐶
As a layperson (retired USAF logistician) I have always enjoyed learning how airplanes are operated and the language flight crews spoke. Your video tutorial was very informative and so enjoyable to watch. Thank You.
I really like these somewhat-more-technical vids. Especially interesting to me is the intersection between the physics of flight and aircraft engineering constraints/considerations + the manufacturer testing regimes. One example in this vid would be the "whys" behind the maximum Mach speed -> airframe integrity and flight control considerations. Unrelated: your ads (in this case, Skillshare) are tasteful and unobtrusive and informative. I deeply dislike web/mobile advertising but your ads are interesting and I even appreciate the advertiser's support for your channel - it makes me think positively of them and I even clicked-through to see Skillshare's offer, something that happens approximately never ordinarily. Thanks for your work, each new vid is something that I look forward to watching.
The other day I had to end my home sim session and sleep so i decided to put my 737 into a dive by pushing the yoke forward at FL360. It accelerated as expected until reaching the end of the speed tape, about 450 knots. A real aircraft would have pretty much disintegrated by now. At this point the aircraft pitched up extremely fast and pitch went from 80 degrees ND to about 20 degrees NU in about 1.2 seconds. The IAS reduced quite rapidly as well since AoA went from "not that much"to likely around 90 degrees. The aircraft then stuck in a pitch up attitude and plunged into the Tasman Sea tail first. Thank you for reading this little story haha.

Some simulators will register damage if configured to do so. X-Plane, for instance, will delete flight controls from the plane--often it models that the tail comes off first, so it will delete the elevator, rudder, and horizontal stabilizer. Good luck after that. :D
Petter I’d like to thank you for bringing my first real passion of aviation back into my life. After getting my private pilots license I was headed to the USNA where I wanted to pursue aviation for the Marine Corp. After a femur fracture in 2004 I was unfortunately disqualified and aviation was too painful to revisit. I can’t thank you enough!!
Speaking as someone who can't land an aircraft in a video game I seriously doubt the future holds a career as a pilot. It always gets messy near the ground. I wonder how many pilots could explain these details so clearly. I mean I'm a pretty good driver but if I tried to explain driving it would soon become waffle.
Very true. That is why teaching is it's own job. Just being good at something doesn't always mean being good at explaining it. I have also noticed this with myself, even when I am good at something I still don't always know how to explain it properly so that others will understand it too. If I was required to teach something to someone and I wasn't able to let someone else handle that for me, I'd probably just let the other person watch me a couple times and then hope that they'd have seen enough to eventually figure it out on their own.
As usual your first officer (the dog) stole the show. The information presented was great but as everyone knows your first officer is the star of the show. 😁
Petter thanks again for a great video. As a flight enthusiast I learned so much I was clueless about. You are amazing in the manner you communicate your material! Happy 2019 and safe travels my friend. BTW I used to fly rev1 727s and then 737s as a kid. I always wanted to be a pilot but the eyes nixed that prospect. The most amazing opportunity as a kid was being in the cockpit during taxi up to the runway. I sincerely appreciate your professionalism and you sharing your experience with everyone. Love your app too. Peace.

Just want to say I took my first flight lesson after watching a ton of your videos. The wind was at ~25 knots so I wasn't so confident during the flight but I'm really looking forward to beginning full time training. Thanks for your mentourship
Good episode, save one small thing. The Lockheed Electras that crashed did not do so because of wing flutter. The root cause was engine mounts that were too flexible. At certain speeds and flight attitudes, P-factor would actually push the engine off-axis, which would change the location of the P-factor, which would push the engine off-axis in a different direction, which would change the location of the P-factor, etc.. The result would be P-factor "chasing" the engine axis in a circle and literally ripping the mount out of the main spar, like a dentist wobbling a tooth to loosen the "mount" before final removal. Perhaps the mount being ripped from the spar DID cause wing failures, but the root cause was the engine, or engines, violently leaving the airframe. The planes were all grounded and, once this was discovered, the engine mounts were stiffened. It was a little hard to get people to fly on them, though! The military uses them to this day as the P-3 sub hunter...and the Coast Guard/NOAA flies them into Hurricanes!
You MUST do a seperate video of your adorable dog. As much as I love and am fascinated and informed by your wonderful videos, I often find I can't tear myself away from watching the puppies hijinks. Perhaps you can create a separate channel. I'm sure he will have a lot of subscribers.
These videos are so concise and clear, when compared to the absolute dragged out basic rubbish shown on TV they really show up how stupid audiences are treated most of the time. This is information I've always wanted to know, finally being conveyed in an entertaining format
I was once told about spitfire pilots who experienced Mach Tuck, they'd end up crashing until one pilot found that if he applied trim, the plane would slowly pull out of the dive.
I will probably never be a pilot in this life, but my grandfather was a jetfighter pilot and I've been fascinated by aviation ever since I was a kid. I love this channel.
Tacoma Narrows Bridge... I am frequently impressed by the range of your knowledge, including things like American bridge distasters! Thanks for another great video.
That description about exceeding mach number and the shifting of the lift backwards. Explains the action of the British pilot when experimenting supersonic speeds, found himself in an uncontrollable dive, and by chance he pushed the stick forwards and brought his nose up.
Happy new year! This video inmediately reminds me of the FedEx 705 incident. The plane was pushed to the limit in order to avoid the takeover. So I can only conclude the DC-10s were really really tough planes.
Could be a great video for you to talk about what to do when unable to comply with a ATC order. Like if you get told a speed that is below minimums or told to land on a runway where there is a wind that exceeds the max crosswind of the aircraft. Or if you are told to do something that you believe is unsafe
That dog is too funny. But yes, the Tacoma-Narrows bridge definitely comes to mind while talking about this stuff. I grew up in the Seattle area and basically every single one of my High School Physics and other science classes have analyzed that bridge incident. Interesting stuff, especially since it can also be applied to Aviation.

You're testing our concentration skills: - do we pay attention to your very good explanation of the matter concerned ?, or - do we laugh about your dog trying to catch your attention ?🤣 Jokes apart, thanks again for this instructing and at the same time very entertaining video
vayalobo, I have watched many mentour videos so professional and here comes that dog. so funny. the dog works, my wife now starts watching mentour now, because of the dog :-)
There are times when I lose my concentration and fail to watch some part, but what I will simply do is to pull back the video progress bar near the bottom of the screen. That is similar to rewinding of the video. That way, I will be able to watch that part again that I missed. I like watching these videos in full detail.
By far one of the very best videos and explanations on TH-cam. Im just vfr now. I want to express my sincere admiration for your guy's ability to reverse engineer a project complex like this and I hope you are extremely successful on a track as you are in the shop
Awesome video! The explanation about the Mach limits was especially interesting. One of the reasons I always loved the 747 was its capability to fly at .92 if the airline didn’t mind the fuel consumption. I loved the long hauls to Asia where the pilots routinely found good tail winds. My daughter loved the idea of traveling at 680+ knots, even if it was technically just the ground speed. There was just something about the way those big birds almost seemed to wallow into the Jet Stream. I will miss them. 😔
Limits are always something derived from KIAS (sometimes it's KEAS or KCAS)--it's the relative wind the airplane perceives. So if you catch a 130 knot tailwind at Mmo, yeah, you're going to have impressive groundspeed without serious risk of something bad. BUT you really wouldn't want to be at full Mmo in this condition as if you got wind shear, you could have a short-term overspeed event. This does happen relatively often, but usually nothing horrible happens other than having to do an engineering report. Most companies allow you to go about 0.02 over Mmo in these situations without having to do a full incident report so long as you promptly returned to Mmo; you have to report that it happened but usually there's no consequences--often the autopilot won't even kick off.
Loved your coffin corner video. Text book explanation, understandable by everyone. In this video (What happens if an Aircraft flies too FAST!!?) you were slightly more technical than I've noticed previously, which I really liked. I'm not an Aeronautical Engineer, just a low end regular engineer. However I have taken some level of interest in Aircraft design my whole life, so I can agree with some limited certainty that what you say about aerodynamics is true. Myself personally, I would love to see more technical examination of topics. Also, when you speak of such technical topics, maybe some external links included in the video? I'm almost a Patreon supporter and will be downloading the app soon.
A little more insight on why ATC changes separation and therefore speed restrictions: sometimes I had to repair or align a piece of NAVAIDS and ATC would be notified and place a restriction on separation/airspeed till the repair or equipment is back on line.
@@jaroslavsevcik3421 I don't think we're ever gonna see it flying...it's nearly impossible to build a efficient supersonic airliner...I think the future belongs to Airbus's 3 engine flying wing design...

Yes...But it all ends right there...Uneconomical waste of British and French taxpayer funds...A maintenance nightmare...Early 60's designed turbojets...A passenger jet with afterburners?? lol...Banned from many airports due to noise restrictions, and over land restrictions due to sonic booms...A very limited destination rich celebrity airliner...Many engineering faults, and one which ultimately sealed its fate...Etc. Those souls on board AF 4590 should still be alive today. The engineering flaws that were "mostly" responsible for that crash were well known for years.
2 things: I have watched many of your videos and I want you in the cockpit of every aeroplane I ever board. Secondly, the star of this video, good as it is, is your wonderful canine companion!
Interesting story my uncle who's an airline pilot in America told me. Southwest airlines is apparently known for buying pizza parties for ATC, especially the TRACON guys. The ATC then kinda "misses" seeing them exceed certain speeds by a few knots, radar isn't THAT accurate you know. Or maybe it was in need of calibration. (note:the pizza party thing is likely a pilot urban legend or joke. ATC controllers are of course, professionals) One time an American airlines pilot was flying into Chicago (which has two airports about 30-40 miles apart, one of which is one of the busiest in the world and the other of which is still busier than most places main airport so similar to new York, the TRACON guys have their work cut out for them.) anyway. The AA pilot was in a bad mood that day or just being a boy scout. He received a transmission from center very early in the approach process requesting he climb back up a few thousand to make way for faster traffic overtaking from behind him. He radioed back and said something along the lines of "Chicago center this is American123 what's our current speed restriction?" to which ATC replied "none other than 250 below 10k" AA pilot then radioed back and said "ok Center, were showing exactly 250kts right now so if someone is passing us from behind we're going to have to declare an emergency due to unreliable airspeed indication. What, are we showing for ground speed on your radar?" ATC replied after a few with "ok American123 disregard previous climb instructions"..... "southwest321, please reduce speed to 230 and remain at current altitude".... "American 123 were showing your speed as just fine here, minor mix up, continue approach".. "ok center, American123, no emergency needed then, we just became concerned when we heard someone was overtaking us while we had 250 indicated at this altitude"... Awkward silence... "Roger American123, problem was on our end, it's resolved now, I'll get back with you shortly".. Now I'm paraphrasing from memory, I know the terminology isn't all accurate etc. And this very well may have just been a "pilot joke" they liked to share, and never actually happened, but I thought it was amusing enough to share. Southwest does have a reputation for always being in a hurry and I thought I'd share based on being relevant to today's video
I'm a newcomer to this channel. Very interesting video. I took a flight once from EWR to LAX (when I used to work for American Airlines many years ago). It was a older model 757 with the huge tv monitors above the aisle. The inbound flight to EWR was 1 1/2 hours late. It was in the fall and the weather was relatively tranquil coast to coast. We got about one hour into the flight and turbulence started. The flight attendants were told to put their carts away and everyone buckle up. They were never allowed to bring them out again for the rest of the flight because I kid you not when I say that turbulence did not cease until we reached somewhere over California. We landed only 30 minutes late and all connecting passengers made their flights (and at the time we were arriving those were the last connecting flights out of LAX). I suspected the pilot put the pedal to the medal a bit more than usual to make up all that time which may have been the reason for that incessant turbulence (that's MY guess). I have flown from NY to LA many times and this was the only time of such prolonged turbulence. Also took a flight from JFK to MIA with a connection to Brazil in Sept 2004. Hurricane Jeanne was paying a visit to NY area. Back then, AA used 767's to MIA out of JFK. Of course we were quite delayed because of the weather (and I was lucky to even get on the flight as a non-rev). I remember that route (normally) took 3 hours. Upon arrival in MIA we had flown a little over 2 hours! I later found out from a co-worker that there were a BUNCH of connecting international passengers on my flight and AA did not want to have to accommodate international passengers due to a delay and misconnect and there was no way a lot of the connection airlines were going to take a delay to wait for all of us. So once again (I think) the pedal was mashed down to the medal to save the company a lot of $$$ that night...LOL. But the funny thing is I do not remember that flight having as much turbulence compared to the EWR - LAX flight. Different experiences in different aircraft models I guess.
Do you mean the computer simulated virtual wing to be fitted to the new Boeing 737 1/2 max. It is a computer that pretends that you have wings. Guaranteed or your next of kin gets the unused portion of your flight refunded.
Great idea to have your buddy as part of the video since s/he hopping from co-pilot to 1st class to coach provides a visual reference in case I need to rewind your videos back to a certain segment...
Mach tuck sounds like a positive feedback loop - the faster you're going, the harder it's pushing you down. So how do you recover from it? Or do you... not?
@@suddeneevee9441 engine to idle is going to not accelerate you further but it's not going to (significantly) slow you down. You can try to extend speed brakes at close to mach 1 but i have the feeling the only thing you would achieve is a sudden loss of hydraulic pressure and a lot of shrapnel falling somewhere at the ground. Comment above is probably right: you recover by relieving yourself (and all of your passengers) of the struggles of life (Not a pilot either)
I think the dog stole the show! Really hard to concentrate on what you were saying with the dog's playing/climbing around. Funny! Kind of makes your videos watchable and enjoyable!
@@wolf310ii I don't know why but that reminded me of an old British Rail advert where they used a locomotive painted as a police car to pull a train over.
This is one of the most fascinating things I’ve ever heard.. I have been meaning to stop watching you for over an hour, after stumbling across you by mistake. Thank you for explaining it so well and letting us into your world 👍
When I was growing up back home in Bethel Alaska before the extended the taxiway to runway 36 well it was back then now it’s 10 but we used to backtrack that runway all the time. I loved it.
Mentour - The old DC-8 had a pitch trim compensator that essentially "pulled" on the yoke as the aircraft approached higher mach numbers, the indicator was on the First Officer's control yoke and crept up at higher speeds to compensate for mach tuck.
The speed limits for taxiing reminded me of a very unpleasant job action by United Airlines pilots in the summer of 2000 ("Summer from Hell"). I was doing lots of business travel at the time out of ORD (Chicago O'Hare), which is United's home hub. The pilots were malicioulsy obedient to the taxi speed limits, refused to fly aircraft with minor maintenance issues, called in maintenance on non-existant problems, and generally did whatever they could to delay flights and pressure the airline to meet union demands. The result was the cancellation of 25,000 flights and the loss of 1,000,000 passengers that summer for United. I recall being very angry at the pilots, who chose to harm their customers in their dispute with management. As you would expect from such a lose/lose tactic, United filed for bankruptcy two years later. Sorry to bring up a bad memory; I love what you do and love the channel. Thanks for the inside information!
Quite comprehensive! Rather enjoyed this one! Felt like I was being giving quality information without being talked down to. Great stuff! Thanks for your great material!! - Lyle in Tokyo
11:16 wouldn't that rather be because the Indicated Air Speed is getting lower and lower than the actual speed as you go up, so the Mach speed only goes down relative to the IAS, but it's just that you're actually going much faster.

I will probably never be a pilot in this life, but my grandfather was a jetfighter pilot and I've been fascinated by aviation ever since I was a kid. I love this channel.
Your dog is so lovely 😜
Kejesuhツ really, so charming. Don’t gives a darn about what his owner is talking about, but knows everything about attention seeking behavior 😁
I had a poodle during my first years. One just like his but with a lighter color. They are super great dogs!
Thats a cat in sheeps clothing!
Dont drop the two poodles are gorgeous, such great dogs very loyal.
@@beagle7622 those are cats in sheep costume!
Tacoma Narrows Bridge... I am frequently impressed by the range of your knowledge, including things like American bridge distasters! Thanks for another great video.
Doggo wants a TH-cam channel too. He's practicing entrance already!!!!
Doggo de Ruggo
Love your first officer in the video. Looks like it's time to take off.
that dog OWNS that couch! 😂
I bet he does !!
The couch hell, that dog owns HIM!
That description about exceeding mach number and the shifting of the lift backwards. Explains the action of the British pilot when experimenting supersonic speeds, found himself in an uncontrollable dive, and by chance he pushed the stick forwards and brought his nose up.
Wow! I thought plane speeds were limited by engine's max thrust. Fantastic explaination, as usual. Learned a lot. Thank you, Sir
Ahhhh another Christmas episode! lol And, I always love the dogs helping out! 👍🏼🐶🙏🏼
Happy new year! This video inmediately reminds me of the FedEx 705 incident. The plane was pushed to the limit in order to avoid the takeover. So I can only conclude the DC-10s were really really tough planes.
even though i'm in a flight school studying all of this, this videos it continues being extremely helpfull.
thank you!!!
Hes got a magical rug moving on side of him
Lol
Thank you mentour this video really helps me become a better pilot in Infinite Flight. I'm working on not getting a overspeed warning under 25000 ft.
The test pilots have some balls!
hell yeah but it's gotta be fun
or they're really poor and they need to get rich really fast haha
Especially on commercial aircraft, where there are no ejection seats.
@@bohan9957 they do have parachutes though, but that didn't help the A400M test pilots, did it? :/
Apparently they have flaps
You explained the aerodynamics of the commercial aircraft at relatively high speeds in a very simple and excellent way! Good video.
You would make a great lecturer.
Beyond Backwater I believe he is a training captain, so it wouldn’t surprise me if he actually does lectures to pilot trainees.
Could be a great video for you to talk about what to do when unable to comply with a ATC order. Like if you get told a speed that is below minimums or told to land on a runway where there is a wind that exceeds the max crosswind of the aircraft. Or if you are told to do something that you believe is unsafe
That dog is too funny. But yes, the Tacoma-Narrows bridge definitely comes to mind while talking about this stuff. I grew up in the Seattle area and basically every single one of my High School Physics and other science classes have analyzed that bridge incident. Interesting stuff, especially since it can also be applied to Aviation.
video of that bridge failing is insane
Resonant frequency wasn’t taken into account on that bridge....
I had just watched the show regarding the coffin corner. This one explains it a little more and helps very much thank you!
"You wont get arrested midair if you dont land"
Aviation weeky tips
ATC: Mentour, you have to eventually land. You will arrested.
Mentour: jokes on you ATC. This is a Tesla airliner. It’s all electronic and has supercharging solar panels. I can fly nonstop.
@@danielaramburo7648 simple, the Air Force shoots you down
@@mirkwoodphotography2089 no. Remember when that airport worker stole a turboprop and was joyriding being chased by fighters? They didn’t shoot him down. To be shoot down, you have to be serious and legitimate terrorist threat.
@@mirkwoodphotography2089 to be shot down, you need to heading in direction of the capital building, an important landmark building like the Empire State…… but if you keep an altitude where you can’t ram buildings, and have not said terrorist threats, they will wait until you run out of gas.
@@danielaramburo7648 Capitol building, you're welcome
19:35 is the most animated I've ever seen your doggos! xD
That dog!!!
Gorgeous !
Attention at last, and so happy at that.
: )
I know hes cute..
😁
I watched all ur videos, boy u teach me so much about aircraft, I owe you so much, thanks so much for these videos, appreciate it so much!
You're testing our concentration skills:
- do we pay attention to your very good explanation of the matter concerned ?, or
- do we laugh about your dog trying to catch your attention ?🤣
Jokes apart, thanks again for this instructing and at the same time very entertaining video
Indeed. It’s all part of your training.
vayalobo, I have watched many mentour videos so professional and here comes that dog. so funny. the dog works, my wife now starts watching mentour now, because of the dog :-)
There are times when I lose my concentration and fail to watch some part, but what I will simply do is to pull back the video progress bar near the bottom of the screen. That is similar to rewinding of the video. That way, I will be able to watch that part again that I missed. I like watching these videos in full detail.
By far one of the very best videos and explanations on TH-cam. Im just vfr now. I want to express my sincere admiration for your guy's ability to reverse engineer a project complex like this and I hope you are extremely successful on a track as you are in the shop
I must warn you, that dog of your’s is a thief. He is stealing the show. Son ma ma bitch man! :)
I can agree with that so much!
The dog is the best part
Awesome video! The explanation about the Mach limits was especially interesting. One of the reasons I always loved the 747 was its capability to fly at .92 if the airline didn’t mind the fuel consumption. I loved the long hauls to Asia where the pilots routinely found good tail winds. My daughter loved the idea of traveling at 680+ knots, even if it was technically just the ground speed. There was just something about the way those big birds almost seemed to wallow into the Jet Stream. I will miss them. 😔
Limits are always something derived from KIAS (sometimes it's KEAS or KCAS)--it's the relative wind the airplane perceives. So if you catch a 130 knot tailwind at Mmo, yeah, you're going to have impressive groundspeed without serious risk of something bad.
BUT you really wouldn't want to be at full Mmo in this condition as if you got wind shear, you could have a short-term overspeed event. This does happen relatively often, but usually nothing horrible happens other than having to do an engineering report. Most companies allow you to go about 0.02 over Mmo in these situations without having to do a full incident report so long as you promptly returned to Mmo; you have to report that it happened but usually there's no consequences--often the autopilot won't even kick off.
Sir you do very good videos. I like the details provided. Keep it up!
Loved your coffin corner video. Text book explanation, understandable by everyone. In this video (What happens if an Aircraft flies too FAST!!?) you were slightly more technical than I've noticed previously, which I really liked. I'm not an Aeronautical Engineer, just a low end regular engineer. However I have taken some level of interest in Aircraft design my whole life, so I can agree with some limited certainty that what you say about aerodynamics is true. Myself personally, I would love to see more technical examination of topics. Also, when you speak of such technical topics, maybe some external links included in the video? I'm almost a Patreon supporter and will be downloading the app soon.
The puppy has become an integral part of the videos Hehehe. That dive test sounds very scary....
Wonderfully informative even for a lay person. I fly constantly and love learning new things about planes and flight, thank you.
We’re doing absolutely fantastic mate, thanks for asking 😉
A little more insight on why ATC changes separation and therefore speed restrictions: sometimes I had to repair or align a piece of NAVAIDS and ATC would be notified and place a restriction on separation/airspeed till the repair or equipment is back on line.
I tune in for the dog, what a cutie.
That pup is so cute. Doing its own thing in the video
You were right, it was fascinating! And love your adorable dog.. (glad I watched to the very end :-)
All of your presentations are quite educational but, this one by far resonates the most to me. Thank you.
Happy new year, and so looking forward to 2019 with your vlogs
The real stars of many Mentour's videos are the dogs. Love them.
Love that dog!
I'm 100% a cat person but I love that dog to bits
“Chill, Think and Know” I’ll remember that. Brilliant.
Supersonic Airliners...
...R.I.P. Concorde / R.I.P. Tupulew Tu-144
Boeing is working on a supersonic aorcraft. Currently it is more like a prototyping but maybe we will live enough to fly it.
@@jaroslavsevcik3421 I don't think we're ever gonna see it flying...it's nearly impossible to build a efficient supersonic airliner...I think the future belongs to Airbus's 3 engine flying wing design...
[Error] : not enough window seats in that thing. Leave flying wings to the military.
"R.I.P. Concorde"?? I hope it's still burning in its grave. Worst airliner ever put into service. Was it Sexy? Yes...Advanced for its time? Yes...The fastest? Yes...But it all ends right there...Uneconomical waste of British and French taxpayer funds...A maintenance nightmare...Early 60's designed turbojets...A passenger jet with afterburners?? lol...Banned from many airports due to noise restrictions, and over land restrictions due to sonic booms...A very limited destination rich celebrity airliner...Many engineering faults, and one which ultimately sealed its fate...Etc. Those souls on board AF 4590 should still be alive today. The engineering flaws that were "mostly" responsible for that crash were well known for years.
@@jimco5852 nah...
2 things: I have watched many of your videos and I want you in the cockpit of every aeroplane I ever board. Secondly, the star of this video, good as it is, is your wonderful canine companion!
I'm listening while I'm watching the pup just chilling playing with the toy 😍😎😉
Interesting story my uncle who's an airline pilot in America told me. Southwest airlines is apparently known for buying pizza parties for ATC, especially the TRACON guys. The ATC then kinda "misses" seeing them exceed certain speeds by a few knots, radar isn't THAT accurate you know. Or maybe it was in need of calibration. (note:the pizza party thing is likely a pilot urban legend or joke. ATC controllers are of course, professionals) One time an American airlines pilot was flying into Chicago (which has two airports about 30-40 miles apart, one of which is one of the busiest in the world and the other of which is still busier than most places main airport so similar to new York, the TRACON guys have their work cut out for them.) anyway. The AA pilot was in a bad mood that day or just being a boy scout. He received a transmission from center very early in the approach process requesting he climb back up a few thousand to make way for faster traffic overtaking from behind him. He radioed back and said something along the lines of "Chicago center this is American123 what's our current speed restriction?" to which ATC replied "none other than 250 below 10k" AA pilot then radioed back and said "ok Center, were showing exactly 250kts right now so if someone is passing us from behind we're going to have to declare an emergency due to unreliable airspeed indication. What, are we showing for ground speed on your radar?" ATC replied after a few with "ok American123 disregard previous climb instructions"..... "southwest321, please reduce speed to 230 and remain at current altitude".... "American 123 were showing your speed as just fine here, minor mix up, continue approach".. "ok center, American123, no emergency needed then, we just became concerned when we heard someone was overtaking us while we had 250 indicated at this altitude"... Awkward silence... "Roger American123, problem was on our end, it's resolved now, I'll get back with you shortly".. Now I'm paraphrasing from memory, I know the terminology isn't all accurate etc. And this very well may have just been a "pilot joke" they liked to share, and never actually happened, but I thought it was amusing enough to share. Southwest does have a reputation for always being in a hurry and I thought I'd share based on being relevant to today's video
Man, I love your dogs.
I'm a newcomer to this channel. Very interesting video. I took a flight once from EWR to LAX (when I used to work for American Airlines many years ago). It was a older model 757 with the huge tv monitors above the aisle. The inbound flight to EWR was 1 1/2 hours late. It was in the fall and the weather was relatively tranquil coast to coast. We got about one hour into the flight and turbulence started. The flight attendants were told to put their carts away and everyone buckle up. They were never allowed to bring them out again for the rest of the flight because I kid you not when I say that turbulence did not cease until we reached somewhere over California. We landed only 30 minutes late and all connecting passengers made their flights (and at the time we were arriving those were the last connecting flights out of LAX). I suspected the pilot put the pedal to the medal a bit more than usual to make up all that time which may have been the reason for that incessant turbulence (that's MY guess). I have flown from NY to LA many times and this was the only time of such prolonged turbulence. Also took a flight from JFK to MIA with a connection to Brazil in Sept 2004. Hurricane Jeanne was paying a visit to NY area. Back then, AA used 767's to MIA out of JFK. Of course we were quite delayed because of the weather (and I was lucky to even get on the flight as a non-rev). I remember that route (normally) took 3 hours. Upon arrival in MIA we had flown a little over 2 hours! I later found out from a co-worker that there were a BUNCH of connecting international passengers on my flight and AA did not want to have to accommodate international passengers due to a delay and misconnect and there was no way a lot of the connection airlines were going to take a delay to wait for all of us. So once again (I think) the pedal was mashed down to the medal to save the company a lot of $$$ that night...LOL. But the funny thing is I do not remember that flight having as much turbulence compared to the EWR - LAX flight. Different experiences in different aircraft models I guess.
Hey Mentour, have you seen the new wing concept that Boeing just announced?
What is it ??? Your not talking about the Flying "Wing" concept are you ?
yeahxwqererrrrr yum
It's a trussed wing design
@@charleslacombe359 nah he's reffering to the semi erected wing
Do you mean the computer simulated virtual wing to be fitted to the new Boeing 737 1/2 max. It is a computer that pretends that you have wings. Guaranteed or your next of kin gets the unused portion of your flight refunded.
Great idea to have your buddy as part of the video since s/he hopping from co-pilot to 1st class to coach provides a visual reference in case I need to rewind your videos back to a certain segment...
Mach tuck sounds like a positive feedback loop - the faster you're going, the harder it's pushing you down. So how do you recover from it? Or do you... not?
You recover somehow, you go from an uncomfortable airplane seat to a padded, ergonomic coffin, which can be understood as a recovery.
I ain't a pilot, but my intuition says: "slow down = drag". So things like airbrakes, engines to idle, or something like that.
@@suddeneevee9441 engine to idle is going to not accelerate you further but it's not going to (significantly) slow you down. You can try to extend speed brakes at close to mach 1 but i have the feeling the only thing you would achieve is a sudden loss of hydraulic pressure and a lot of shrapnel falling somewhere at the ground.
Comment above is probably right: you recover by relieving yourself (and all of your passengers) of the struggles of life
(Not a pilot either)
I think the dog stole the show! Really hard to concentrate on what you were saying with the dog's playing/climbing around.
Funny! Kind of makes your videos watchable and enjoyable!
I love those test pilots. The bravery field in their character properties says 99.
The 3D graphics of the routes is quite cool looking. Great visual.
The little police men with the little lasors! 😂
stopping the airplane, climb on a ladder to the pilot window: "Do you know why i have stop you?"
@@wolf310ii I don't know why but that reminded me of an old British Rail advert where they used a locomotive painted as a police car to pull a train over.
Pilots must use Waze! :)
This is one of the most fascinating things I’ve ever heard.. I have been meaning to stop watching you for over an hour, after stumbling across you by mistake. Thank you for explaining it so well and letting us into your world 👍
Can you please introduce us to your puppies ?
When I was growing up back home in Bethel Alaska before the extended the taxiway to runway 36 well it was back then now it’s 10 but we used to backtrack that runway all the time. I loved it.
Lolz! I think the little dog (Brownie) is amazing! I know about over speed to be honest, I just love the Dog! 👍💯
Nice touch with the green and red pillows. Thanks, I know where the couch is oriented
0:15 seconds in and I wanted to make funny comment about speeding ticket but now I am not so sure.
JUST DO IT
That is to perfect
I wanted to make a funny comment about getting Vd
Mentour - The old DC-8 had a pitch trim compensator that essentially "pulled" on the yoke as the aircraft approached higher mach numbers, the indicator was on the First Officer's control yoke and crept up at higher speeds to compensate for mach tuck.
Happy New Year Mentour :)
The speed limits for taxiing reminded me of a very unpleasant job action by United Airlines pilots in the summer of 2000 ("Summer from Hell"). I was doing lots of business travel at the time out of ORD (Chicago O'Hare), which is United's home hub. The pilots were malicioulsy obedient to the taxi speed limits, refused to fly aircraft with minor maintenance issues, called in maintenance on non-existant problems, and generally did whatever they could to delay flights and pressure the airline to meet union demands. The result was the cancellation of 25,000 flights and the loss of 1,000,000 passengers that summer for United. I recall being very angry at the pilots, who chose to harm their customers in their dispute with management. As you would expect from such a lose/lose tactic, United filed for bankruptcy two years later. Sorry to bring up a bad memory; I love what you do and love the channel. Thanks for the inside information!
I want to cuddle the dog. 🐶😍
It's a pupper. Who wouldn't? 😂
You have always keep on calculating
a few things which are (very) relevant according the speeds.
Thank you for the very interesting information.
My dad overheard VD several times and was concerned why was I watching VD related stuff 😂
"Dad, i aint planning to slam a plane into a skyscraper"
Excessive VD does indeed lead to a loss of parts!
Quite comprehensive! Rather enjoyed this one! Felt like I was being giving quality information without being talked down to. Great stuff! Thanks for your great material!! - Lyle in Tokyo
is there any effect on the engines from over speeding, can they stall at high speeds?
The whole clip is was listening to your voice, but soo enjoy watching your dog, what a sweet cute dog you have.
I love the dog ! Great character !
11:16 wouldn't that rather be because the Indicated Air Speed is getting lower and lower than the actual speed as you go up, so the Mach speed only goes down relative to the IAS, but it's just that you're actually going much faster.
