What is it that convinces people that the PF sussed UAS when the a/p quit? Why is he expected, here, to instantly apply procedures to a mode that is not known? He has been in turbulence, experienced variations (if ONLY VS), that may have him thinking: A/P LIMIT.
In which case: NORMAL LAW retains. He is also committed to control the aircraft, how is he to know there is A/L in his near future?
In the BEA there is PNF mention of the loss of speeds, and reversion of LAW, but ELEVEN seconds LATER.
So prove, regardless of bias, that the PF was not flying NORMAL LAW up to eleven seconds post a/p drop?
Besides, in A/L, he has PITCH protection, so his focus even after he sussed A/L would quite naturally be on ROLL, perhaps at the expense of PITCH.
Not what he "SHOULD" have been flying, but what was possible.
Throughout, and including the prior 32 episodes, where is the instantaneous recognition of UAS by the PF? Yet "Do Nothing", "Wait", are the demands of the ex post brigade here, who would have immediately sussed UAS and been the hero.
