What could the autoflight have done to get this aircraft to so obviously be nibbling at aerodynamic STALL?
How's an a/c "nibbling at stall" supposed to do that 3000 ft climb?
Just before!

In NORMAL law αsw = 23° (fixed value for all flight phases)
In ALT & DIRECT Law αsw = function of M and S/F config.
S/F is not applicable, in this flight phase αsw = function of M only.

αsw---- MACH
10.8°-- <= 0.28
9.9°--- <= 0.35
7.6°--- <= 0.53
5.2°--- <= 0.75

3.8°--- <= 0.866

-Inhibited M >0.866
-Inhibited on GND (if not in test)
