Unfortunately, unless one has experience in how an A320 flies in the stall, one cannot work out if the bahviour of the aircraft to those control inputs is as would be expected.
May I assume that in simulator training on the A320 that the student only takes it to "recognition" of a stall and not a full stall? Is the sim able to simulate a full stall?
Same thoughts with me... but with the dynamic manouevres, and no doubt high Load Factor, it might be inhibited? I am not sure of the logic to which it works?
Are you A320 qualified?
