try not to think about it as "restraining" AoA as anticipating where it will be if the aircraft continues to slow (which it would do until the engines have spooled back up).
When the elevators movement oppose the AoA increase, it is a clear restriction.
But nice theory of your own making, too bad it is not detailed either in the documentation or the BEA report.
What if the hypothesis that 17.5 degrees should be consistently held with full back-stick in High AoA mode is incorrect?
What if the Airbus documentation is wrong ?
Is it not possible that 17.5 degrees AoA represents the absolute "do-not-exceed" maximum alpha from a normal limit of around 15 degrees AoA? If Chris's translation is correct, the wording of the BEA report is certainly consistent with that scenario. This interpretation would also be consistent with Capt. Corps' narration on the video.
17.5 deg of AoA for CONF 3 is the target to maximize the performance, that's why Airbus chose to call it Alpha Max.
The video demonstrates how rapidly Alpha Max (15 deg for CONF FULL) is obtained.
But again ... nice theory of your own making.
