Re: your opinion v/v AL2 v. DIRECT LAW at climb (handoff). You neglect to mention the negation of g command. PITCH, DIRECT, would have well defined suggestions as to 'recovery'?
As in, do you have an opinion on what to then do with elevators? That would be important, should they be limited? RATE + DEFLECTION?
Not just the AUTOTRIM would be missing, NO?
I hope I am not being simplistic, but I see a very definite (dis)connection between the "Helpful" bits of AL2 verse the DIRECT behaviour of DIRECT.
Simply put, and given that she "Did what was commanded", had she been DIRECT, she would not have pissed away her energy in a g commanded climb, and the PF would quick like a mouse had a STALL, with NOSE DROP, BUFFET, and a very focused PNF. Captain would not have been called. As it was, Captain's ultimate presence was not helpful. Recovery? I can't be sure, but as a pilot which would you prefer?
The honesty of DIRECT LAW, or the "HELPS" of AL2?
Your CALL?
Q1:
AZR Your quote did not look familiar, so I went back, and don't see in my post a question such as you quoted.
edit. OK, I think I mean what you see. Would the A/C have STALLED, conventionally, with FULLNU elevators, and -3 THS? I think yes, You? I also think recovery would have been straightforward, though of course wicked challenging, I'll give it a miss!
Q2:
AZR, that is my point, but I disagree that the AoA will not change, as the Cl does, and the a/c will accomodate the "new" fuselage orient, with Tail. The relationship is dynamic, very dynamic. That is why the difference twixt AoA and Longitudinal alignment is critical, altering the "comfort zone" of the system (aspect) changes relative to all the surfaces, and a moving lift surface changes the balances with greatly divergent rates, as it moves. imo.
