Touch'n'oops
Sorry, I confused Alternate Law with Direct Law. In direct law autotrim is disabled. That is what occurred in the Air New Zeland crash, where the trim was left at the last autotrim position (near stall) and the aircraft then pitched up as airspeed increased and stalled which they did not recover from.
If the aircraft was in alternate law then the autotrim was enabled. If that is the case, then can we assume that the change in trim from 3 degrees nose up to 13 degrees nose up was commanded by the auto trim system? If you push nose down, how long does it take for the autotrim to respond? As somebody asked earlier, could this high pitch trim setting made the aircraft unrecoverable?
