Yes. It is possible PNF was alerting PF to AL with loss of RAS, as a second, and more determined way of getting the PF in AL 'mode'. Most of PNF's comments were of this type: "Watch out..." "Less Lateral..." "Loss of speeds......Alternate Law". He was, if not the scold, the short fused "instructor", albeit seemingly with good motive.
Yes, again. PF's seeming variable mind set re: overspeed/STALL occurs in a domain where they are not radically different in value. At least initially. We must not forget that the aircraft at a later time warned him of impending STALL each time as he was about to recover. We do not know yet, but at many times post a/p loss the a/c and PF were at odds, as PNF was with PF. Finally, with the arrival of the Captain, who seemed of no use, was there any time after the loss of autoflight that any one was on the same page as the others?
With such a fundamental lack of basic airworthiness, it at times seems bizarre to focus on details...... To what effect?
He did deploy brakes. He was ready to a second time, in presence of Captain, when Captain said "No, do not use brakes". For all we know, it was the lack of a complete stow of a starboard side spoiler that caused the chronic Right Wing drag/drop.
Do we know exactly when Alternate Law 2 selected?
