The function of the High AoA protection is to keep the airplane out of the stall. So it is entirely logical that this function is activated at an AoA that is sufficiently close to alpha-max so as not to hinder normal operations, yet far enough below it to ensure correct operation in all reasonably expected operating conditions. These considerations govern the selection of alpha-prot.
- I am aware of all that, but it does NOT explain why the a/c was pitched by the system towards alpha max from level cruising flight - that is the explanation I am seeking. I can see absolutely no logic in this function.

Can anyone?
