(...) If the pilot releases the sidestick the angle of attack returns to alpha-prot and stays there. (...) To leave the angle of attack protection the sidestick must be pushed (...) forward.
For how long does the AoA "stay there"? (Alpha Protection) what does it take to gain Nose Down?

"Push the stick forward"?
How far forward? Does THS freeze, or ennable the protection?

At the outset, just after loss of auto, Bonin commanded a climb. Two seconds later... "STALLWARN.....cricket, cricket, Master Caution......" and from Robert, "What was THAT?.....". Was he referring to the SW, or to BUFFET? That would qualify an exceedance of Alpha Prot, especially with an assistance from WindShear? (updraft). Is this the reason Pitch remains in gee? ALII (b)?

I think I read here that forward stick must be fully forward, something we do not see from Bonin? Once discouraged from applying forward stick by the recurrence of inappropriate STALL warn, would he desist from further attempts?

How does THY pertain to 447?
