I’m sure most of you has flown on a aircraft in winter time, looking out at snow as you as the ground gets further and further away. Think back to that time but now imagine that the ground is not moving away from you but rather coming towards you at a rate of 15,000 feet per minute. This aircarft is literally falling from the sky but the reason for this will prove to be an interesting topic of discussion...
Stay tuned

Please, don't take sponsorship from better help. They're extremely dishonest and exploitative.
Flying over snow covered landscape and the reason for the aircraft falling from the sky is truly "chilling". ....i see what you did there.🤣🤣
Come on man. Still?
Why better help again? Still??
@@YHK_YT what is so bad about them?....genuinly curious
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. 🙂
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 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 .
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.
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.
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.
Me to
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 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)
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.
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😅
@@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.
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! 🤠👍🏼
@@ricktaylor4real 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.
That was a very accurate pronounciation of "Magadan" :)
The lack of visibility due to snow is normally frightening, but combined with faulty sensors... is a freaking horror! I can understand what the pilots went through - I almost had a heart attack watching this story.
“🤘REACH OUT🤘”you Won.
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
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
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.
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.
Pffff..."survived -50°C" I went to school in -56°C because Yakutia and because ЕГЭ was on the way xD
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.
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.
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).
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
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 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.
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
It is somewhat scary that such 'experienced' pilots do not know how to fly an aircraft with diminished automation... although the auto trim was seemingly doing its best to sneakily sabotage all their efforts to stabilize the aircraft... until the pilots finally decided not to crash the plane by remembering this critical component actually exists.
Easy to snipe and play Monday morning. Quarter back. Imagine going 1000s of hours flying a specific prescribed way and then something like this happens out of the blue and during a high workload time and the only other time you’ve seen it is during a sim session perhaps years ago. I do think the crew not sticking religiously to the backup speed tape and setting prescribed thrust/pitch settings is worth criticism, that would be the first thing I’d look to do with unreliable airspeed and would hope it’s what my captains would immediately think too. They got their acts together and got back to the ground safely, have to applaud that
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.
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.
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..
Maybe they believed that all those roller coaster manouvers were just part of the expected turbulence.
@@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.
Everytime you say the word "stabilized" I can't help but giggle. Your accent is the best.
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.
Also you have to realize that Peter probably didn't know BetterHealth is a scam company. But chooses sponsors better than most youtubers.
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)
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.
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.
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!
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
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
Same
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
@@davidelliott5843 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.
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.
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😂
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 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.
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.
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
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.
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
Hello sir, thanks for this " danger in the Sky" I knew nothing about. Glad to hear Airbus developped a backup system regarding airspeed.
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.
“🤘REACH OUT🤘”you Won.
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.
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.
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!!!
Except this particular air crew, they were utterly incompetent. But I agree, the other ones are amazing!
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.
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.
@@djinn666 You should leave it to the experts. There are nine zillion things to consider, and, unless you work in that exact field, you don't have the knowledge to talk about what the ''should be''.
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.
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...
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!!!
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
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.
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.
And did you heard about recent incident with a320 wich landed in the wheat field?)😂 Same airline of corn field miracle.
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.
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 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.
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!
Was just thinking of the old engineers adage at the start of this:
If it moves, and it shouldn't - duct tape
If it doesn't move and it should - hammer
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.
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 UA-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!
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.
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
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
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!
Man, never even flown a simulation but just from watching your videos that "Warning, imminent doom" ring sound gives me a shot of cortisol and dread every time I hear it now
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 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
Wow insane! I bet those passengers were white-knuckling that whole time to Irkutsk! Great work and storytelling,
Petter and team ❤
We don’t really know. It’s possible they only thought it was really turbulent and didn’t understand how serious it really was
@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 😅
They were Russians. So they probably must have thought those damn pilots had too much vodka again.
@@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
Passengers must have been losing it and puking.
these are better than "Mayday" and "Air Disasters". Straight to the point, informative and you're great at narrating.
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!
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!
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.
Wow, I'm surprised they survived. This shows that all pilots need constant re-fresh training!
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.
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🫡
Thank you! Glad to hear you think so.
I’m not a student pilot (financially impossible) but I’ve learned a lot about flying from Petter.
With each passing video, your work keeps getting better. Truly impressive!
We do what we can!
Looking foward to watching your next one!
@@MentourPilot It shows, great episode MP!
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.
Wow. This is crazy. Talk about a rough day at the office. So glad they got this stabilized and landed safely!
I had not heard about this incident. Thanks for covering it and I hope its lessons will be remembered and the mistakes not repeated!
Oh boy, I really didn't think they would make it but thank God they did. What a ride.
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.
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.
That was one of the most stressful videos I've ever watched in my life! Incredible analytical detail. And, thank heavens, a wonderful ending.
I just found your channel and I am binge watching! I fly only paragliders and powered paragliders but many moons ago I was an airline CRM instructor. I would love to see you do videos on both Crossair crashes. Both highly avoidable accidents. Again, GREAT channel. Your English is impeccable, your technical knowledge leaves people like me amazed and proud that its aviators like you who make our travels safe.
I really appreciate the video editing of your videos. It's so well made!
Glad you like them! My team will love to hear you thought so!
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!
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.
Incredible video. I've watched quite a few of your videos now but this one has been by far the most emotional and well produced. Very impressive and impactful work
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.
please check your inbox
I'm glad everyone was safe after the emergency. I think these "near miss" events are really important. Thank you for sharing it.
this is where i'd normally say "bravo to the pilots!" but rather i'm here saying "bravo airbus making such a sturdy airframe" lol
Now just imagine sitting in the plane while those up and downs were happening and try to guess how many seconds you had left to live 😰😅
😂😂😂😂
This is one of the best channels on UA-cam; perhaps the best overall. Many thanks for your great work. The animation is top shelf.
Wow, thanks!
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.
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.
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!
It is incredible with that much experience on that plane how the captain just reacted with instinct instead of reading instruments properly. That tells a lot about the stress experienced there. The controls applied at the moment it was apply are inacceptable. But in the same time i am sure that if the captain was watching this video confortably as i do, he would think that this situation was easy to avoid and several mistakes could be avoided while flying.
The immense bank angle combined with the GPS speed and altitude readings was clearly a large stall indications.
¡Gracias!
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.
