To me, the AoA response makes complete sense as a pilot of the Airbus. What has not been either appreciated or grasped by many, is, from the beginning, this design has required a different way of thinking, a different approach to training, to flying, to anticipating behaviour and to interacting with the machine, and it absolutely requires a positive attitude and approach towards it.
Would it be fair to state that the AB pilot, except for direct law, is really flying the autopilot and not the airplane? Assuming, of course, that the AB FBW system, with its various protections, is really an autopilot with several different interfaces.
It seems to me that, once they stalled, the proximate cause of their not realizing they were in a stall was the fact that the stall warning behaved badly. Put simply, if the aircraft knows that AoA is above the stall number, the stall warning should go on and stay on
until the aircraft is not stalled any more.
