> If the pilots had correctly and quickly identified the problem and run the stab trim runaway checklist, they would not have crashed.
I'm curious how long it takes to run that checklist, and how much altitude would be lost while doing this? How long does it take to reach sufficient altitude to have time for this?
Also, I have a question about stall recovery and altitude. Are there any altitudes for which it is better to go ahead and stall and fall flat out of the sky than to nose down and risk flying into the ground at above terminal velocity? If so, do any automatic systems on any planes recognize you are in such a "must crash" situation and try to pick the least worst crash?
* The clanking sound is the stabilizer trim "runaway". In the video, it starts while the video is zoomed in; when the video zooms out you can see the trim wheels (next to their legs) spinning.
* The trainer (left hand seat) says "rudder", but he means "stabilizer" (he says it correctly later in the video)
* The pilots in a real plane would likely not hear the noise because they will have noise canceling headsets on, but the manual trim adjustment is the big wheel next to their leg that spins very visibly and they would feel the trim pushing the plane's nose down
* The stabilizer trim adjustment is relatively slow - it takes just under 10 seconds to travel end-to-end, so runaway time is going to be at least five seconds.
