If he keeps making videos like this about aircraft systems, I think even as a line training captain he'll someday be out of a job... "So, where did you learn your way around a cockpit?" "Mentour Pilot..." "Ah, yes. Great content on his channel. You're hired. You're starting next monday. Would you like to be first officer or captain?" On a serious note though, this knowledge could possibly save lives in a case both pilots get incapacitated. Someone who's got some basic knowledge about the cockpit, where everything is, and how the plane should behave, could in such case possibly get her on the ground with less damage and injuries than if you just let her do her own thing.

@@joffreyverbeeck1640 It’s a nice idea but if both pilots get incapacitated then everyone on board is doomed. Even if there were someone on board who either is a pilot or knows enough to call ATC to get them to get someone to teach them how to program the autopilot to land, the sad truth is that it wouldn’t matter. Because thanks to the events of 9/11 it’s incredibly difficult to even get into the cockpit because the doors have been reinforced and are always locked.

Alaskan airline flight 261 would be a perfect example of catastrophic failure in the horizontal stabilizer. For those who aren’t familiar with that incident, it was a MD-83 that went down off the California coast in 2000. It was determined that the airline delayed maintenance on the jackscrew in an attempt to save money, but they delayed too long. The jackscrew ran out of grease resulting in the threads to stripping out. This eventually caused the plane to go into an unrecoverable dive and loss of aircraft with all hands.
@chunkyazian3 жыл бұрын
There were 2 factors that contributed to this. When the screw ran out of grease and it was stuck, the pilots used 2 motors instead of one in an attempt to turn it. That was too much for the damaged thread to handle. But the scariest part of this was the M-D engineering. After the thread stripped and the stabilzer hit its down limit, the pilots managed to level off at around 19,000. That was until the down limit nut failed and the stablizer went past the down limit. Had M-D designed it to be fail safe, had there been a bigger nut at the down limit, the pilots might have made it as LAX was in sight
@andrewdavidson76563 жыл бұрын
@@chunkyazian There's no denying that there should have been a fail safe and that the pilots using two motors in an attempt to force the jackscrew ultimately caused it to fail completely. The root cause was the airlines negligence in properly maintaining the jackscrew which resulted it premature wear allowing the failure to occur.

Like @Felix C it was multiple factors. If the screw jack on the 737 fails the Hstab can't travel past the limits like the DC9/MD8x could. Additionally inspection is easy as the jack is in the tailcone not inside the tail. The design is very different as the arm will get trapped between bottom gimbal the safety nut which unlike the DC9 is huge. Finally the pilots sadly did the unthinkable after 2nd or 3rd event. They tried to use the trim again (like normal). If they would have left it and limped back to LA they would have survived.

Oh yes, for doing that, you HAVE to know your wiring very very good, otherwise it is perfectly possible that some other part of the wiring goes off before the faulty light... in which case you have not found the faulty light but the weakest wire... There is quite some margin between the cb's tripping and wire failing, but it is not impossible. And that's the reason we should never test it, even don't suggest doing something like that, bcse people who have NOT enough knowledge (about the circuit, and/or generally) get the impression they could or even should try that too (and get fcked while doing so). Besides, i know a whole line of circuit breakers where holding the lever up would not stop it from tripping...

I was in a DeHavilland Buffalo that was on a return flight From Anchorage, destination Comox. It had a manual unassisted elevator trim wheel in this aircraft with no autopilot. There were a dozen crew in the back and after a few hours of boredom, everyone quietly moved as far aft as possible, and we watched the pilot compensating automatically as his hand hung down casually, just moving the wheel. We all moved forward, and we giggled as we watched him moving the wheel. After three or four times, his head came up as he realized what was going on. He looked back at us, and pushed the stick hard forward, we all got thrown to the floor, and as he pulled hard back, we all flew up into the ceiling, then all falling down. Everyone had a giggle, but we all learned not to mess with the pilot.

I don't fly, but this stuff is fascinating to me. I have been searching KZbin for what "trim" means in aviation. A video like this one reminds me of the frightening prospects of things that can go wrong in one of these massive man-made machines.

An accident with Alaska Airlines happened because of a vertical trim failure due to maintenance scheduling issues. The airplane had not been serviced properly and the jack-screw was not properly lubricated. It then got stripped and came out of the nut that connected it to the horizontal stabilizer and the pilots lost control of the pitch of the aircraft. Not a good thing.

I always thought they were fidget spinners for the pilots to play with when they get bored. Seriously though, trim is equally important for RC cars. When you've got a toy car going 60 miles an hour with less than half an inch of ground clearance, the car is capable of veering off-course and smashing into a curb (or someone's ankle -- or face, if the car catches the air and turns into a kite -- yes that can actually happen) before you even have time to realize something is going wrong. So you have to trim the steering accurately enough that you can punch the throttle and accelerate all the way to top speed with minimal steering input, or else the car will be too unstable to actually drive.
@oliwek703 жыл бұрын
In your RC car example, is it not rather like a deadzone setting, more than a trim ? (you make the deadzone bigger, so that little impulses on the stick are not registered, where a trim acts as a force, and moves the center of an axe in one direction, so that if you release your hand or thumb from the remote, it centers on a value different than the original untrimmed zero value, in your case the RC car would then have a tendency to turn, as a real car with bad wheels geometry). If it is a trim in the case of RC cars, is it because the small car has an issue of wheels geometry, or because of outside factors ? (such as wind, or the track geometry)

@Jim Mork no intention to argue about that,but you can google for the toyota trhottlegate case.a bug in the code of some toyota models who make the car suddenly go full power. not a faulty sensor or similar,a real program bug that make the car go full throttle.

@Jim Mork there was quality control staff who got fired because they found they were using substandard parts,making them fit by drill and hammer,specially the wing forks,those who later needed replacement and much more parts.there is no regulators actually,boeing certifies itself their own airplanes and the regulator just accept the incoming documentation,without test or verify nothing.thats why they are not more the standard for the rest of the world like before.there are documentarys here on YT,and they seem legit. The toyota case,it seems the code was a pretty nasty mess,plagued with patches over patches never cleaned.finally they accept to pay to the US goverment on the condition to not look further. dont know who is worse.

It is a weird video. There is obviously no mention about Max as if the pilots were not allowed to talk about it anymore. It sounds and looks like some Boeing promo video. The airlines using them are probably counting on that people will not be asking about the aircraft type after lockdowns are finally lifted being happy to be able to fly somewhere at all. But I think that the whole era of cheap flying in cramped economy class represented by obsolete 737 is over. People will be willing to pay more for their safety and comfort and the bet on Max entering the service again as if there was no pandemic is wrong.
