- while I fully agree that, as with the PGF A320, power reduction would have aided recovery, I think you are confusing pitch attitude with AoA? - it is AoA that stalls a wing, not pitch. Pitch attitude is not in reality relevant to 447 from 38000' down. Even when the pitch attitude fell below zero the wing, I think you will find, was still fully stalled and being kept stalled. It is extremely straightforward to stall an aeroplane at a very low power setting if enough nose-up force is applied - otherwise airtest stalls could never be done.
