-----------------------------------------------------
One of the most time-critical decisions a pilot will ever take under normal circumstances is to reject a landing at low altitude. It requires instant decision making, great handling skills and timing.....but what if the aircraft then refuses to follow the pilots commands and instead does something completely unexpected.....Stay tuned.

I am a Captain with SAS, and happened to land that very same day in CPH, about 30 min prior to TP754. I do confirm gusty winds and rwy 30. Flying the A320 series these days, but with vast prior Boeing experience, I also confirm that most pilots on the Airbus will choose flaps full in gusty weather, as this gives better engine spool up and better tail strike clearance. On that day, as we requested pushback for the return to Stockholm, we were told the airport was temporarily closed due to an ongoing event. Once we got approval for push and start, we were told to hold short of taxiway Z to let TP754 pass ahead of us. We clearly saw the reverser doors hanging out on engine nr 1 as they passed with a bunch of rescue vehicles in tow... Great video by the way, as always, Petter.

I was on a flight about a month ago that had a bird strike on the right hand engine, and it happened when the pilots were past V1 on the takeoff roll. Because of your channel I was able to explain to the other passengers what happened, why we were climbing out slower than normal, and what the pilots were going to do about it.

[@justwantresults8768]

@@the_real_espada 40 years of engine company experience here, but no pilot training. Yes, the engines are tested during certification for various bird strike encounters, but impossible to test for every scenario (think USAir and Capt, Sully on the Hudson river). At that point it is pilot training and procedures: evaluate engine parameters, alternate airports, aircraft altitude and performance and make a decision. If the bird is ingested in the engine core, there may be a smell in cabin since that's where pressurized air comes from. Still, an engine shutdown is only based on observed parameters. Bottom line: it's the pilots call, as it should be.

TAP’s safety standards are exceptionally high and has been very proactive in updating its fleet, incorporating new aircraft models that meet the highest standards of safety and efficiency. This includes adding next-generation aircraft like the Airbus A330neo and the A320neo family to their fleet. One of the safest airlines in the world.

I am a frequent flyer with TAP, including domestic flights to Madeira and Azores. The portuguese archipelagos are known for their strong and sometimes gusty winds, unpredictable weather conditions, as well as short runways. TAP and SATA pilots are very experienced in maneuvering and landing in difficult weather conditions. For instance, I was in a flight to PDL in which we were surprised at the last-minute by a thunderstorm and the pilot was able to land the plane safely.

I lived for a while near Marrickville in Sydney. You could sit in Elmore Park there and you'd be directly under the flightpath for the Sydney Airport. We'd have a picnic and marvel at the 747s which seemed so low and close it felt like you had to duck! In Newtown, every time a jet came in to land, conversation in the lounge room or kitchen would pause until you could hear again. You got so used to this bizarre ritual that it was automatic and you didn't think about it but it would have been very strange to people new to the area; everyone sits there mute for 30 seconds as the house rumbles and shakes and then they continue from exactly where the conversation left off mid sentence 😂

Every industry should look at how the aviation system works. Being able to launch an indepth investigation from a single incident into something much much bigger and not stopping at just blaming the pilots is incredible work. Being able to bring forward changes on a massive scale even when death was not a factor is very laudable. Another top notch video Petter! And amazing work on the animation team from continuously improving one video after the other.

[@jamesx4952]

This reminds me of Tam 3054

[@scottkirby5016]

I think a major component is that aviation includes reporting and analyzing sub-critical (airframe loss/death) incidents on a regular basis as well as no-fault reporting. I think many other industries could be boosted by that combo, be it healthcare, structural engineering, etc.

[@BabyMakR]

We are fast approaching the time where computer programs in general are too complex for humans to understand all of the interactions one section of code will have with all of the others. I think it was in I Robot where the old man talks about the Ghost in the machine. People infer he was talking about consciousness but it really refers to unintended interactions of one program with another. And it is only going to become more and more common.

[@lifeteen2]

As an engineer, 1 in a million, or 4 sigma compliance by humans is incredible, it's not really possible to expect humans to perform better than that. If you need better reliability than that, you MUST go up the hierarchy of controls and make engineering changes.

[@peterebel7899]

[@tomhejda6450]

There's only about 1/1000 go-arounds, so that's about 1/1000 go-arounds being executed after reversers selected. That _is_ something you can improve by better training.

[@BlueSkyUp_EU]

​@@tomhejda6450A go around is not the only situation when this design flaws can have deadly consequences. What about a faulty sensor that would show left side in the air even though is not? And why is the system set up to preserve thrust reverses while airborne? That's extremely dangerous and needs to be addressed asap.

[@MBSteinNL]

​@@BlueSkyUp_EU Thing is that if the reverse thrust disappears while the wheels aren't bound down by the spoilers some unexpected behaviour can occur. The issue here is more that asymmetric commands can be executed in this regard. Which can be partially explained by the memory items of the system regarding delayed execution. Something which has killed people before with both Boeing and Airbus airplanes. Especially the 2-3 seconds after an unknown/unintended bounce remains a safety hazard it seems.

[@ByzantineDarkwraith]

@@BlueSkyUp_EU I don’t think it was intended to preserve the reverse thrust when airborne (specifically when airborne and the thrust lever is commanding the reversers to be stowed, I mean), because why would they do that on purpose, even though in this case it did have that effect, and it is a serious issue.

I want to express my appreciation for these accident investigation report videos. Since I have spent a lot of time downloading and reading official accident investigation reports from several different countries, I know how technically dense those reports can be. Not to mention that as a lay person it is often difficult to grasp the importance or significance of certain data points, or sequence of events. You also provide some much needed background information that explains certain systems and/or procedures, as well as the justification for those procedures. Plus, you also provide an insider perspective on how the lessons learned impact and shape the present and future of aviation. That is very fascinating for me. THANK YOU!!!!

Assuming Petter's diagrams are correct, having the Right thrust reverser co-ordinated only with the Right gear.

Also, since the c/c are auto-generated, they can get things wrong: in one video where I did enable them, 'fore' was written as 'four.' At least in that case it was easy enough to know what was meant. But still, any sort of music is just not needed when we are trying to listen to him tell us why a plane experienced whatever or why a pilot did or didn't do something.

Perfect lessons once again! I would like to add that it is also very important to keep your hand on the thrust levers until you are completely sure the aircraft is on the ground. Sometimes you see pilots reaching for the thrust reversers while the aircraft is floating above the runway. There is no need to hurry!

[@philipdemaeyer1665]

You contribute to safety for the whole industry. I even take alot from the airline industry to my job in the transport on the road as trucker. Per example: recently a client complained that she was calling of her earliest customers due to unforeseen delay of the truck. The dispatcher had seen trough my onboard PDA that I was surrounded by heavy traffic on al routes, and that I could not make it on time. So he/she called the store by default. Knowing and agreeing with something I took from your videos; Aviate, navigate, communicate. The store its online buy and collect in the store manager, became angry as I navigated the traffic well, and managed to make it within the smallest margins of time to unload and get everything to the customers. Unjust of her, but I understand why she reacts the way she did. My priority is still, operating the vehicle (truck) safely, navigate using terrain knowledge, experience and prior to start map studies on the route with possible alternatives. Then, only then, communicating my decision and possible ETA to the dispatcher.

I've seen the decrab in person many times when watching planes land on high altitude airports..

[@riaanlouw1874]

@@Vincent_Sullivan And it's funny seeing aB-52 landing, with its 20Deg max crab angle built into the landing gears, and then continue taxing with that crab angle.

[@IngoSchwarze]

Below an earlier video of Petter's, there was a comment that went roughly like this: "During the landing, the passenger in the seat next to me, clearly an very nervous flier, suddenly shrieked: 'Look out of that window, you can see the runway right there! The aircraft is heading into a totally wrong direction, we are all going to die!' - I calmly explained to that person what a crab landing is, why pilots occasionally do that, and that i learnt that from Petter's videos. That person was super grateful." So i think passengers do sometimes notice when a large-angle crab is executed. Or is this an urbal legend? Admitted, i'm quoting this from hearsay.

Thanks Petter, always, and thanks coffeeguy for highlighting how I too am positioned when faced with a video of more than a few minutes! Only Mentour videos can hold my attention, and there’s so much to learn, and it’s always shown so that a non pilot like me can truly understand the scenario, the risks, opportunities, etc, and how a combination of human error and aircraft limitations or shortcomings can result in crises. Cheers. Si.

[@browntrout1156]

Great video Petter, well done. Just goes to show how quickly things can go wrong.

[@bw162]

Hard to understand why the criteria for reverser deployment or stowing on either engine was specific to the squat switch on just the engine side affected. Logic would suggest that they would not be deployed/stowed unless both squat switches were in the same position.

[@xyz-md2mv]

Good point

[@peterprokop]

It is not that easy. If you do that, it might cause other problems: If there is a fault in one of the squat switches, you might have no reverse thrust at all, or it can introduce unwanted delays in reverse deployment when the plane lands in a way where there is insufficient load on one of the gear sets due to crosswinds. You might also introduce other new failure modes in the deployment logic in case one of the computers or sensors monitoring the deployment fails. So before you deploy a solution, you have to check how often these systems fail, or you will end up making things worse by introducing more single points of failure than the current system has. This is one reason why it takes so much time to engineer a fix: You need to account for all the probabilities of components failing or wrong sensor readouts, and think about fail safe conditions and redundancy in the whole system as well.

[@bw162]

It didn’t work out to well in this case did it? And to your point, airlines restrict single engine landings to only idle reverse thrust and use max auto braking. And I’ve never experienced a cross wind that with the boards deployed, there wasn’t immediately sufficient weight on the gear struts. If not, you are describing a situation where the aircraft is out of control and continuing the landing would not end well. Not saying that it is “that easy”; just taking exception with your examples.

[@freeculture]

@@peterprokop the planes are designed and tested to completely stop without reverse thrust, its use is merely to save on brakes and maintenance. This is yet another reason why pilots should not be too quick to engage it as it happened here. Auto brake will do its job either way.

[@eileenbauer5266]

I'd like to improve on my previous comment: if the engine control computer (let's call it ECC) gets a signal that the plane has put force onto the plane tires, it should not be a yes or no one time situation. If the reverser is selected and force is applied, then reverser comes on. If a second later, weight is removed, the reverser is closed (turned off). On two engine aircraft, if one engine has reverser open and the other doesn't and it cannot close the reverser then it needs to go to idle

[@awesomedn]

This story gave me some goose bumps. I’m a software engineer with almost 20 years of experience. I just don’t understand how this possibly wasn’t accounted for during the system design phase. It’s pretty obvious that both engine modes should always match. There should never be a situation when one engine is commanded into a forward thrust mode, while the other is commanded to stay in the reverse mode. If there’s a disagreement between the left and right controlling signals - both engines must remain in their current configuration. Such simple logic would ensure that two engines will never be commanded into different modes

[@alexandermonro6768]

Retired embedded systems engineer here. Yes, it shouldn't be possible for one side of the aircraft to "think" that it's on the ground, and so enable reverse thrust, while the other side "thinks" it's airborne, and so inhibits it. Both engines must always be in the same thrust reverse state.

[@ivarwind]

I was thinking the exact same thing. As he began explaining the split-up system of sensors and engines, I already knew - but couldn't quite believe - what was coming. It seems completely bizarre that anyone would make a system separated up in left and right so that it can think that the one side of the plane is safely on the ground simultaneously with the other side being airborne. Maybe it should still be possible to reverse thrust based on only one sensor - just in case the other sensor is malfunctioning - but obviously this should apply to both engines, and applying full thrust to one engine while the other is in reverse, should not be possible - or be accompanied by some serious alarms!

[@TheGrejp]

I was looking for a comment like this, it's incredible how no one else seems to be mentioning it. As an electronics engineer it's hard for me to understand why the system is set up like that as well. The entire system rests upon the assumption that both sides will receive the same inputs which is never really a given. I'm actually surprised this didn't happen sooner!

[@alexandermonro6768]

@@orlandopockets6372 So what do you understand?

[@d2009wong]

Good point. I worked on some ships that could couple or decouple propulsion systems as needed. Also it seems there isn't a manual switch (overrides the logic) to stow the reversers back as the pilots had to shut down the engine. A blinking warning should be displayed on the main screen if the reversers are sensed not at the locked stowed/deployed position.

[@theAessaya]

Here in Eastern Europe the spring weather can be really unpredictable as well. It's not uncommon for it to cycle through all four seasons in one day's length. Very interesting story, and I'm glad everyone walked from this unharmed. Although the software engineer in me wondered why they chose not to allow for stowing of reverser flaps regardless of the weight-on-wheels switch. That didn't look sensible to me. Glad they're addressing it.

[@Zilahi-Branyi_Laszlo]

I don't really understand why the system built in a way that not only activation, but also deactivation of the reverser is prohibited in air as there is no reason for the latter as I see. OK, you never should find yourself in air with actvated reverser, but if somehow it does happen it seems obvious that it would be handy to able to disengage it. I build way less safety critical systems, than an airplane, but always take care to implement solutions for operating statuses that theoretically never be able to engender as things that theoretically not able to engender may be possible in a way that nobody thought of.
