Well, without watching your video yet. If I wasn't climbing immediately after rotation, my first instinct without even thinking about it would be to check the flaps...

BOAC 911, March 1966 crash! Must Do Video content!!!

[@NS-Sherlock]

why aren't we developing a system to prevent critical information going unnoticed? A small screen in the cabin which is set to destination airport, showing all the recent updates like an instagram feed, no matter which radio channel you are using, what you are hearing or not. Each tower has its own channel, where they constantly post stuff like Lufthansa flight bla bla.. aircraft type bla bla.. go around due bla blaa.. Emirates flight bla bla... aircraft type bla bla.. landed, experienced heavy tirbulance Qatar Airlines flight bla bla.. aircraft type bla bla.. landed... bla bla.. Pilots can use the screen to monitor what is going on at the airport no matter if they are on the other channel or different people talk over eachother and something goes unnoticed. This whole thing can be done without any complicated engineering application. You got internet or some other connection both on the plane and in the tower right? All you need is few cable connections, a small monitor in the cabin, a software update or an extra computer for the tower where they can automatically or manually enter the recent activity, and a server somewhere to connect it all globally. I swear with help from a few friends, i can fix this dumb problem in a short time. On the other hand the entire industry is acting like there aren't many simple solutions to such simple problems. The cost of such a system would be laughable even if a single airline was paying for the entire thing for every tower and plane, alone. I don't even know how many times we heard "they didn't hear it" in your videos, and i dont know how many of them ended with tragedy. I am not sure if the industry is full of really intelligent people or just a random bunch who just convince themselves that they are intelligent. People follow eachother's every move on social media, we all know who was where, what they ate, what they did.. and all that crap. You can't follow what is going on at the airport where you will attempt a landing soon. Sorry for the language but as a passenger, hearing such stuff is just pissing me off.

Coming from a software development perspective I find it interesting that there is no feedback to the users (in this case the pilots) when they press a button that is inhibited. Especially such a critical button. Could be a callout like "inhibited" or a buzzer sound or whatever. I think such a feature could have gotten the pilots attention and prevented the accident from happening. At least it would insert another slice into the Swiss cheese.

[@MentourPilot]

That’s was actually similar to the feedback of the final report as well.

[@brunoais]

I strongly agree with you. I was going to write about the same in a comment but you ended up writing it yourself

[@MarsJenkar]

As someone who works in quality assurance, I agree. That there wasn't sensory feedback about the TO/GA switch being inhibited was very significant, and if I'd encountered something like that in testing a system like this, I'd have marked it as a potentially critical failure, or at least a very significant failure. Glad to hear that this was addressed in the final report.

[@VosperCDN]

That would make sense, as even my bog standard, non-critical home computer bleeps or chirps when I click a button that doesn't then activate.

[@jetporter]

What an excellent idea. Usually the levers move when the button is pushed. Personally, on aircraft equipped with autothrottle, I'm already pushing the levers as I press the buttons. But I note this captain had flown almost his entire career with this company, who mandated 100% autothrottle use. He was therefore probably 100% expecting the levers to do their thing. Some kind of haptic or aural feedback would be very useful if people insist on flying aeroplanes lime this.

A few years ago I watched a video titled "Who Destroyed Three Mile Island?" and it really changed my perspective on how we blame people for accidents. In this Emirates accident, like many others, it is very easy to just blame it on pilot error, but that does nothing. People will always make mistakes. It's much more important to determine why they made that mistake to prevent it in the future.

[@TimesWithJames]

Fortunately the ethos in aviation (the the level in which I fly - UK GA - as I document on my channel 😉) is to not 'blame' but to 'learn'. Indeed, if we never learn from an incident, we can never improve systems to negate similar scenarios in the future, thus saving many more lives. Alone, this is why aviation is almost the safest way to travel today.

Elizabeth….that is so true. Training to influence muscle memory and mental state responses to a potential situation changes from seconds to unknown…hopefully we did the right response choice, and there was time for mechanical performance to take effect. This was rather routine until the shear started the sequence. I guess the thing to take away from this is, confirmation of performance of inputs made, despite the automation. As a helicopter guy, I just learned something about the landing system on this aircraft, that normally given enough altitude could have made it a good day…maybe an (audio) alert could be added…perception dictates what we do, and then there is what is expected from the machine, and sometimes it doesn’t match up.

When you have a dozen buttons to press in a short period of time, and your training has given you the impression that these buttons always work, I really don't think it's the pilots fault at all here when one of the buttons doesn't work as expected. Even if they perhaps could have verified it. Heroic effort by the captain and crew member combing through a smoke filled cabin looking for passengers left behind.

[@lbowsk]

They had one button to push, and two power levers. They only did the first one. Airplanes will not fly uphill at idle thrust. That's pretty basic. You want to go around? You need to add thrust. These planes have been successfully flying Go-Arounds for almost 40 years. Why did THIS crash happen? Because they neglected to add power.

[@tlangdon12]

I think that the captain was deficient in assuming that the autothrottle would always work. Watch enough Mentour Pilot videos and you realise that many of the systems have various points at which they are inhibited and many reasons why they might fail. The operation of any button, but especially a critical one such as the TOGA buttons on the throttles, needs to be verified by someone.

​@@tlangdon12 Mentour did a whole section of the video on how it was entirely plausible for pilots with their training to not know about the inhibition.

I am a long retired airline pilot and I thought this was one of the best analysis of a crash that I have seen. For perspective I started airline flying as a F/O on the Lockheed Constellation and retired as a Captain on the B-757 so I flew with no autopilot to the full autoland systems. I believe that too much emphasis is placed on the auto systems today and there is just not enough "hands on" flying. In this case the Captain hit the TOGA switches and just assumed that the autothrottles were working. When I was flying an Air Florida plane took off from Washington National in snow and freezing rain without turning on the engine anti-ice and didn't push the throttles forward beyond the EPR limits, which were incorrect due to the ice, and crashed into the Potomac River. I always felt that if I was ever in that type of situation I would break the throttles pushing them forward before I hit the ground. For this reason I never hit the TOGA switches without following the throttles with my hand and if they weren't moving fast enough I helped them out. The automatic systems of today are fantastic and have made flying even safer but they don't replace the pilot they should just enhance the pilot's abilities.

[@CaptainSteve777]

Good stuff. Re: "For this reason, I never hit the TOGA switches without following the throttles with my hand and if they weren't moving fast enough I helped them out."

[@FlyingDoctor60]

Glad to read that seasoned line pilots do what I, as a private pilot, see myself doing: when you need thrust for a go-around, don’t just push a button….ADD THRUST! Re training, I think it would be beneficial to have new pilots learn to fly the sim manually in every flight regime from takeoff to touchdown first, then add in automation one system at a time. These are, after all, just great big airplanes that obey the same laws of physics as little ones. The nose controls the airspeed, thrust controls rate of climb, and every pilot should be capable of safely flying them manually before being allowed to use automation.

I think the Potomac River crash has been covered on this channel. Sounds familiar and I seem to recall there even were some survivors...I'm a firm believer in old-school practical/pragmatic thinking. I appreciate wise use of good technology but the trend seems to be more and more contempt built into mindsets. Kinda scary to think a 30 something yo with that much flying experience would overlook something so critical due to habitual reliance on automation. Also, as some have mentioned, no clear warning upon pressing a button for a function that's been deactivated seems ridiculous. The amount of technology and thought that goes into these machines and nobody thought about THAT? Sounds to me like pragmatism is not only lacking in the cockpit but also in the design and engineering rooms. As technology becomes more impressive and complex, we also seem to be going backwards on so many levels.

@@papapetad 3 similarities as I see it between the 2 accidents. 1. They had not been trained properly for the procedure (training can never cover everything). 2. They were performing a procedure they had never done (takeoff in ice and very unlikely the B777 pilot had ever flown a very low go-around in real life). Neither 1 nor 2 should cause an accident. 3 is the big fail. They both commanded the airplane to do something but failed to monitor it to make sure it was doing what they wanted it to do. That is piloting 101. Getting step 3 wrong can/will cause a crash.

Lol, the gear actually already touched two times and they didn’t notice it. They were stupid enough to not notice throttles were completely idle and didn’t pay any attention that the speed was dropping dangerous low during a steep climb. Automation or not paying attention to speed when you’re trying to climb from a low attitude should literally be basic instinct to a pilot or anyone trying to fly a plane, yet this videos argues that automation has made them forget to do so. It’s akin to saying that if you have a good-enough calculator then you don’t need to know why 1+1=2, it was down to the basic instincts and in this case the pilots didn’t have any. It’s actually a whole reflection of their thinking processes and the style of problem-solving they adapt, many flight documentaries have shown how younger pilots in this era often overly-rely on automation and instead have lost more basic skills such as just observing the aircraft and watching the instruments, so its clear dilemmas like this is really only unique to younger pilots. Don’t pretend to sound smart and say “99.9% of any pilots” would have done the same because they wouldn’t have, these pilots were “young “ and failed to notice something overly-simplistic because of over-reliance on automation.

Excellent report. As a retired 777 pilot I can see how this would happen. The reliance on automation was always a problem that our training department always covered during simulator sessions. One item not mentioned was engine noise. When the power is advanced to a high- power setting you can hear it quite well in the cockpit. Problem is in high stress situations the body starts to change in that your visibility starts to narrow (tunnel vision) and your hearing ability decreases. The stress of a low go-around which is one of the most dangerous procedures a flight crew can do would increase stress. I have witnessed many a time where pilots are affected by excessive stress while flying combat in a helicopter in Vietnam. I always briefed new pilot on this problem. After a while most pilots got use to the dangers of combat, so their stress levels dropped.

I was going to say, wouldn't the pilots have noticed that there was no spool up sound and no feeling of acceleration (being pushed into their seat) from the TOGA thrust?

@@carbon1255 There's never been a flawless pilot or airplane, and never will be. The key is to have priorities in order. Some things matter more than others (like adding power on a low go-around).

I'm sorry to disagree or at least partially disagree, but there are simply far too many examples within the airline industry of economic greed and political issues being placed above safety and transparency. How many accidents, featured on this channel even, have been caused/partially caused by poor maintenance or poor training - if these lessons were being fully learned from why do these remain causes of accidents? A few more specific examples of safety and lesson learning not being the priority include the 2019 English Channel Piper PA-46 crash that killed a footballer and his pilot, and revealed a world of reckless and dishonest rule breaking and lack of accountability within the private charter industry; the infamous missing Malaysia Airlines Flight 370 demonstrates the level of political interference and the lack of any apparent willingness to spend money fixing the issues raised in the investigation (such as proper tracking of flights or updates to aging 'black box' technology) clearly shows that cost is often placed above safety - a point further demonstrated by the disgusting conduct of Boeing throughout (and their overly close relationship with the FAA) with the 737 Max accidents, where so many safety corners were cut for purely financial reasons; or perhaps the attitude of airlines that flew passenger flights over Ukraine during the conflict in the Crimea and eastern regions in 2014 that resulted in the shooting down of a KLM plane, where they simply pointed out that nobody told them not to, so presumably according to them it was fine to fly over warzones without informing passengers to keep fuel costs and flight times down.

[@danelen]

I am a total lay person on this topic but your comment is what my impression was as well. Seems like once the pilot hit the TOGA buttons it should have warned him of the auto thrust and perhaps even disengage it altogether so he has thrust control back? In any case, it seems you can easily say what the pilot could have done to prevent this after the fact but it seems unreasonable to have expected him to have thought of that given his training and how much was happening in the seconds he had to respond.

[@MGSLurmey]

@@danelen What I'm struggling to understand is why Boeing would make the auto throttle disable the TO/GA buttons at low altitude, knowing full-well that a go around is extremely time sensitive and a high workload situation. If the pilot hits full throttle, it should go to full throttle, no questions asked. It feels like less a safety mechanism and more a sign of distrust in pilots. There is no good reason that I can think of to restrict the TO/GA buttons when a pilot can just as easily force the thrust levers to TO/GA at any stage of flight manually. It only serves to allow an error such as the one highlighted in this case, that being the thrust not being applied in a scenario wherein the pilot is used to using auto throttle exclusively. If the buttons cannot be trusted to do their expected job, they should simply not exist. TO/GA buttons should initiate TO/GA thrust, no exceptions.

Maybe a bit of confirmation bias on the PICs part on the throttles not moving forward, but when you expect a system to react a certain way because that's how its gone in your training (when they throw issues at you), it's much much harder to catch it in high workload situations.

Yet the pax in 3C who could see and hear the entire medical emergency unfold just 2 rows in front of him had the fucking audacity to complain to me (when I was securing the cabin for the 2nd time that night) that he was going to be late for his dinner reservation, luckily for me he had undone his seat belt while we were waiting for the paramedics to tend to the man that was having the stroke and all I needed to say to him was "sir please fasten your seat belt for departure, as I'm sure you can appreciate, the other passengers onboard are anxious to depart by now and won't appreciate any undue delays" was worth the look on that posh asshole's face to have said it as nice as I did coz he didn't know how to respond and didn't open his mouth for the entirety of the flight after that, RESULT 🎉🎉🙈🙈😂😂😂

Thanks for another wonderful video Petter. Learned the new term , "Children of the Magenta line". Paused the video to look that up. While I don't work in aviation, the increased use of automation in many fields, makes it tempting for older workers who lived through the manual to more automated ways, to feel a sense of superiority about their increased instant recall knowledge of the inner workings. In that heat, 50C, from my understanding, more speed is needed to generate lift than at 25C. Idle thrust setting surely sealed the fate of the aircraft.

[@rainaldkoch9093]

You are right. Quantitatively: 50 instead of 20 °C decreases the air density by 10 %, so that 5 % more speed would generate the same lift. I guess that this effect (as well as air pressure) is already factored into the suggested speed profile.

As a programmer for the past 25+ years, I know how critical it is to plan for all possible scenarios, no matter how unlikely they may be. In my profession, failing to do so may cause a program to crash, but nobody dies. Sadly, that's not the case in all professions. It sounds like the airline took the now-common "it'll never happen, so don't waste time thinking about it" mindset when designing and implementing its pilot training. This accident is the tragic, but inevitable, outcome of that line of thinking.

[@traveller23e]

As a programmer, I know that no matter how hard you might try, it is in practice impossible to plan the optimal outcome for all possible scenarios in a system with any level of complexity. At some point the human in the system will act in a way you didn't expect, or the computer will kill one of the processes, or a server developed by a different team will return a web response you didn't expect. It's not always a matter of assuming something will never happen, it's just as often or more often that something just never occurs to anyone as a possibility. And yes, there are plenty of software houses that rush stuff to market, there's plenty of code that assumes a computer's clock time won't be set to before the Unix epoch and just figure if it's an issue the code can be patched, but when it comes to systems with a high importance such as these, that require a lot of certification and so on, it's probably best to assume the mistakes weren't made intentionally to cut costs unless such a motivation and deliberate decision can be proven.

In the case of programming, it means, for example, to make sure every possible input is considered when using an "if" statement. Too often, I've heard people say something along the lines of "that will never happen, so don't waste time programming a response for it". To address your examples: "At some point the human in the system will act in a way you didn't expect" - Don't you validate your input? Don't you show an error message, flag an error condition, throw an exception, etc if an input is invalid? "or the computer will kill one of the processes" - In a system where this is possible, wouldn't you have something in place (especially in a critical application in which failure can result in loss of life) that would verify all processes are running and show an error message, flag an error condition, throw an exception, etc if it detects a process is not running? "or a server developed by a different team will return a web response you didn't expect" - Don't you validate the responses you receive and show an error message, flag an error condition, throw an exception, etc, when an invalid response is received? If you answered "no" to the above questions, then you are the type of programmer about whom I was speaking.

[@ginger7344]

101 is the hottest I’ve experienced in Ohio and I thought that was awful. Hope to never see 120

[@RubyS.1]

It was 118 in Sacramento couple weeks ago. I left Sac got to Vallejo where it was 114 and it felt so much cooler. It's actually painful when it's that hot

[@philipvandoorn6470]

Love your video's, Petter. I am a ships Captain, Master Mariner as we call it, and find your attention to CRM very instructive. Even through we move in 2 dimensions and you do in 3 dimensions, we have to deal with a very large amount of untrained ship' officers that we encounter constantly. So trained officers will react and operate predictably, while the majority unfortunately does absolutely not. We are constantly required to use BRM, bridge resource management, to deal with complicated situations that would not be there if everyone had followed the proper training. Thanks for your ' absolutely fantastic' insights. I am a better ship' captain because of it.

[@Esperologist]

I agree, it's easy to throw around blame without checking contributing factors. It's not quite the same, but a a boss at one place I worked accused me of messing up. Two orders going out were cross shipped (went to the wrong customer). As it was a small company, I was the primary order picket and shipper... which would imply it was me (as the only other employee was the boss). I showed up to work and he reamed me out about it for an hour, and I couldn't say anything because he was so upset. I didn't recognize either order, so when he left I went into the physical records to see what notes were written (we wrote notes on every record). Flipping through the stack, I was remembering each order and shipping it out... black ink, my writing. I get to the two in question... blue ink, his writing. I didn't bother telling him because he would just get angry again about being proven as the one to make the mistake. Anyway, just proves that if you jump to blame then you can miss the real culprit.

"Automation reduces workload when workload is low, and increases workload when workload is high" I'm paraphrasing a quote I read once, but I find it very interesting that we are constantly looking for ways for the equipment to help us do a better job, but it's often at the expense of our own understanding of how things work. Not every user can be an expert on how software was designed, but you almost have to be as a pilot.

Good video, and great analysis of the root causes by the accident team. Easy to see how you can become completely reliant on a system if that's the way you're always trained.

[@donc9751]

Thank you Mentour Pilot! You do an absolutely amazing job explaining in perfect detail every aspect of what has happened during these aviation incidents !!!

Gracias por tan excelente descripción y explicación de lo ocurrido en este accidente,como siempre el análisis técnico de los hechos y los factores contribuyentes son ejecutados de la mejor manera posible para ser entendidos por expertos y por los que no tienen mucha experiencia en aviación. Muy buen trabajo de nuevo gracias.

I’ve watched shows like this before but watching you with your expert commentary makes these so much more interesting and educational. Thank you so much for being here and teaching me something new.

[@Rana_Tahir]

Can't forget that day 3 Aug 2016 , I was on job at dxb on ground and I saw the crash live from my eyes, it was a very hot day and suddenly black smoke covered all the dxb airport , all the aircrafts suddenly disappeared from the sky and all pushback aircraft were sent back to the bays. It is very informative video as its been six years I didn't know what actually happened until I watched this video.

[@NicolaW72]

👍

[@samrackham4774]

Such a great insight into an invisible force. As a frequent flying passenger I’ve often felt clear air turbulence, cross winds etc but never really given a thought into what goes on in the cockpit during these times. As always your analysis is so understanding big love ❤️💪

[@jaimeroman2406]

Amazing video and analysis. I’m not a pilot I simply love travel. The extent of knowledge and training and expertise involved in your profession is amazing and awesome. Your dedication is absolutely incredible. I just love it. Thank you.

The fact that ALL passengers and crew members survived is a miracle.

At the beginning of the video Petter did not warn about casualties, so I somehow expected that.

I remember this story. In typical Emirati fashion they kept the Emirati pilots name classified but had no problem with throwing the Australian co-pilots name in the dirt

What about the New York EK flight that almost smashed into a residential area in Dubai due to the crew overrelying on the automation? I'd really would love to see an episode about this incident

[@To_masz_Problem]

I love these videos. I could be watching them all day. I hope that you have a lot more of them planned for the future. Keep them coming. Great work. :)

[@teim2002]

This is a deep analysis, and always reminds me of the power of coordination and the effects of the failed systems.

[@robinnce]

Another great video, thanks Petter, you deliver a wonderful mix of storytelling and education. I had to look up “Children of the MAGENTA line” , good pub quiz question!

[@ErikHare]

This is not the first time you have noted that prior flights needing to go around was not known to the pilots who had an accident.

[@flagmichael]

An excellent point, I think. Knowing things are going to get active would be an improvement.

[@yourfriend5144]

Rip fire fighter😢 When you said only the captain and a senior crew member are left onboard to see if someone is still in the plane, that statement sent shivers down my spine. A true captain❤

[@nickybateleur]

EK's (over?) reliance on automation is something I have heard about before. My ex, a former bush pilot, flew the A330 and, latterly, the A380, for Emirates and told me on more than one occasion of his concerns regarding the "training in" of over-reliance on automation, and of insufficient situational awareness outside of the cozy glow of cockpit instrumentation - especially in light of the EK407 incident in 2009.

[@CaptainSteve777]

And Asiana 214 at SFO and many more. Yes, It's a huge problem.

[@danielschein6845]

When I was training in a Cessna-152 I was taught to constantly monitor the plane's speed throughout the final and in a go around. I wonder why airline pilots don't do this since it seems like a common theme in many crashes is that they don't notice that the automation isn't doing what they expect with the throttles.

[@kickedinthecalfbyacow7549]

Swept wing aircraft fly target attitudes rather than just airspeed

[@fltof2]

Having flown only small planes, I suspect while flying jets is similar in many ways, it’s also very different. The non-instant reaction time of a turbine, especially after having been idle for a long time must be substantial. Imagine coming in for a landing in a C152, engine at idle, and at 20’ you try to initiate a go-around, but your instructor delays the power lever by 5 seconds. I’ve never tried it, but now I want to. :-) I think big jets are missing a tactile feedback on the throttles, similar to haptic feedback on the iPhone. But then again, that’d just be one more thing that could break.

[@flagmichael]

I understand what you are saying, but the pilots probably expected anomalies in IAS as the winds shifted,

[@JoshuaTootell]

More like, imagine if you never touched the throttle on your 152 and are shocked when the throttles you never touched didn't do what they were supposed to do. To clarify, there isn't a delay in the engines responding, only that it takes a long time to reach full power. Think of it more like trying to accelerate hard on the freeway with a manual transmission, and never downshifting out of overdrive. It will take a while to get some speed built up. But as soon as you start adding throttle, you will get thrust, but just in slow increments and too little too late in this case.

[@toddsmith8608]

B777 has a few more systems than a C152. Might as well compare a 12' skiff with a 9hp outboard motor to an ocean liner.

[@gabsgames90s]

Thanks for all of the effort you put into these videos. They've been a fantastic source of education since you take the time to explain a lot of interesting details about the way certain systems on these aircraft work. I've been going through a lot of these lately for both entertainment and learning. I also really appreciate that you present the information facts first without manufactured drama, but are still sensitive to loss of life and injuries in the accidents.

[@ratboygenius]

I'm not a pilot, but I am fascinated with aviation. I love your videos because you are a great story teller.

[@nutsbutdum]

25:19 I literally threw my hands up in disbelief. Why do people do that!? - "Oh look, the engines are on fire and the cabin is filled with thick smoke. Quick let's all start fiddling with the luggage compartments!"

[@nightfury8930]

Ik for some people their belongings are more important than other lives and the flight had departed from trivandrum and some malayalis are ignorant

[@litchfiedr]

Reliance on autopilot seems stronger with Emirates.. not checking for themselves that things are happening like they should do. Great work by the cabin crew

[@blatherskite9601]

Excellent narrative, Petter - as usual! Details that only a practising pilot would be able to present, and evidenced by the 11.454 views within 3 hours!

Thank you!

[@GMAtheory]

Hi Peter...I have made this comment before, but I always enjoy your analysis of how things went wrong and digging into the details. Although I work in a completely different industry I always pick up a valuable lesson. As always great content and thanks for all your hard work.

[@sharoncassell5273]

My Dad was a firefighter but rarely talked about it. But I knew sometimes he came home smelling of burnt wood & smoke. He said he was in a fire. Of course. Wind affects the position of the fire in a house. Like planes, the wind direction makes a difference.

[@priceyA320]

In my opinion most of the “blame” for this accident can be laid firmly at the feet of the Auto-throttle design. Pushing the TOGA button and not getting TOGA?! That’s crazy. The Asiana SFO accident is also one where the 777 A/T is implicated. Without getting into a Boeing Vs Airbus argument I think Airbus does this better. Want TOGA? Push the levers to the stops. Need to stop? Close the thrust levers. No buttons to push and no ambiguity on what is happening.

[@flagmichael]

Yes - particularly so when the conditions for disarming TO/GA are not intuitive and there is no annunciation of the switch operation being ignored.

[@Milesco]

@ Billy B. Totally agree. This was a major design flaw, not pilot error. As you said, a TOGA button ought to mean what it says! Otherwise, what the hell is it there for?

[@lbowsk]

Funny, every B777 checkride at my airline includes a low-altitude go-around for this very reason. And every B777 pilot KNOWS that GA is inhibited during a short window close to the runway. Every pilot is trained and knows to ADD THRUST MANUALLY, you know, actually FLY the damn airplane. You screw it up, and you don't pass the check. You don't add thrust manually, and you don't pass. It's not that complicated. The 777 has been flying for over 30 years. Can anyone name another B777 accident implicated by this system? Yeah, no you can't. There is nothing wrong with the system. Pilots just have to know the systems of their planes and how to properly fly them. You hit the GA buttons and you add power. Say it with me now...."Going around, TOGA, Flaps 15, Pos Rate-Gear Up, confirm/set missed approach altitude." We say it prior to the approach every time. It's not any more complicated than that unless, of course, you don't know WTF you are doing or what your airplane was designed to do and when. When you teach pilots to FLY, they fly. When you teach them how to merely "push buttons and pass the check" you are asking for trouble. Just look at Emirates other B777 trick, the "No rotation Take off" in Dubai. I'll not get on an Emirates flight.

[@priceyA320]

Interesting point Steve. I’m sure those Emirates pilots passed all their checks and knew all about how the auto throttle worked. Didn’t stop them getting it wrong. The auto throttle on the 777 was a factor in the Asiana 777 crash in SFO. This very KZbin channel did a piece on it. So, there have been 5 777 hull lose accidents (not counting on ground fires etc). This one, Asiana into SFO, British Airways into LHR fuel icing, and the two Malaysian Airlines ones. One of those was a shoot down and the other a mystery. That leaves 3 hull loss accidents of which the auto throttle is more than a casual factor in two of them. I don’t think that is insignificant or can just be put down to pilot error. Experienced crews who passed their checks made these errors. I’m not 777 rated but have many years on the 737 so am very familiar with “thrust hold” etc and for my money it’s a poor mode that can be a contributing factor in and incident/accident.

[@___DRIP___]

I’m so glad I was recommended this channel. It’s so much better than those air disaster shows that used to be on Discovery channel. Great use of MSFS too. Loved this
