the A330/340 implementation of autotrim always defers to the pilot as to what is "acceptable" when the systems are in a non-normal configuration
- you are still 'missing it'! Not in the case of 447, it didn't. The pilots had no idea what they were doing, coupled with a design fault in the stall warning logic, so the system just carried on willy nilly as programmed - and to call that 'deferring' is sad. It is like holding up 4 fingers to a blind man and asking him how many.
Anyway, Dozy, we are entering Oozlum bird land, so I'll sign off with you.
