at impact, the Horizontal and Vertical velocities sum for a FLIGHT Path of 45 degrees descentYes?
Yes, and with 16 degrees nose up that gives an AoA of 61 degrees as asserted by gums. But the BEA numbers for most of the descent -- pitch 15, AoA 35-40 -- imply a much shallower descent. The airplane was almost uncannily stable during much of the descent -- steady AoA, no spin, and 40-degree wing rock correctable with ailerons is pretty nice behavior with AoA > 35 -- but that may have changed. It is not clear to me whether thrust went above idle again after 2:12:02; at low altitude thrust could affect angle of attack.
