Is it desirable to autotrim in the stall ?
That is a bit simplistic, ehh?
It only autotrims into a stall if:
1) A serious degradation of systems occurs (Alternate Law 2). (This is by definition a clearly exceptional case)
and 2) The pilots continuously (for quite some time) point the Nose of the Airliner where it abso-f$&§ing-lutely (I saw this one in another thread and liked it so much I had to borrow it
) doesn't belong.
Indeed as a behaviour itself it is not really particularly desirable but this should normally really not be a problem. Why it became a problem in this tragic case is one of the reasons that this thread is doing so well 3 years after the incident. It is simply mysterious and shouldn't have been expected to happen to an experienced Crew. Yet it has.
