Lonewolf - I'm having difficulty with the concept of pulling the nose up to 'avoid a stall'?
BOAC:
Given that I used to teach stalls and spins in smaller aircraft, I am as well.
What I understand is that, if you are in the low altitude/terminal environment, on approach, and you get a warning of approach to stall, the response isn't typically trained in AB 330 as "lower the nose" but instead (and I think the assumption here is in Normal Law) to set an attitude (nose above horizon) and max power and fly out of it and away from the ground.
With Normal Law, the protections would usually help you not stall in the process. That habit pattern, likely trained, and possibly even the most recent in terms of a sim event, would heavily inform the response of a pilot being surprised by a stall warning. But then, we are not so sure that "stall warning" even penetrated, and as BEA finds, it is not shown that it ever did.
Granted, more of the folks discussing this take the PF's actions as a sort of remedy to UAS ... but did the crew ever really declare and establish that they assessed UAS as their condition? That isn't clear either.
If I misunderstand the general response and actions action taken to avoid a stall when stall warning goes off, my apologies to AB pilots.
