Les histoires d'alarmes de décrochage... y a pas que les vitesses, mais aussi les angles d'attaque à prendre en compte
he only reliable way to do this is I think, by using an IRS calculated AoA and not from air data. The problem with this accident is that ADR1/2/3 showed AoA1 froze initially, and then lagged behind AoA2 and AoA3. And after the stall, AoA3 spikes differed from the other 2 at times, and that AoA2 and 3 diverged too at one point. The ADR data cannot produce consistent data for long enough for the FBW to produce a continuous warning in the first place. Airbus has done it by "if airspeed is valid and AoA is too high, produce the stall warning". The thing is, the stall warning is designed to keep you away from entering the stall. Once you enter the stall and the AoA is too high, the ADR would have difficulty in self-reconciling itself and produce the warnings.
