Hi PJ2, thanks for all you have added here. I have a simple, perhaps an even simplistic question(s), hoping you have the time to reply.

Re: your last post, what are your thoughts relative to LAW and the STALLSTALL @ a/p drop, and after PF's first control input? Had the a/c entered ALAW 1 or 2 at that point? If so, wouldn't the Alert have been somewhat close, (following) the a/p loss alerts? Would the AoA have been responsible for the Warning? If so, could the AoA have been influenced by either UP or DOWN Flow? Could the AoA have been (transient) in either very Low or very High values?

Is there any chance that the a/c could have been in Normal Law long enough for the Alert to have been triggered by greater than AoA 23 degrees? Or, if a DOWN Flow, a negative AoA?

If in ALAW 1 or 2, Would the AoA have been indicating legit? If so, how could it then silence (Cricket, STALL) and allow for a somewhat large increase in PITCH? Also a climb to 380? At the zenith of the climb, when PITCH 16, and AoA 6, instead of decreasing, could the AoA have actually been increasing to +6? I know many would appreciate your thoughts...
