At the beginning of the Air Caraibes (ACA) incident that happened last fall, the situation looks rather close to that of AF447, at least with regard to these elements: same FL (350), about same gross weight (206 t), ADR disagree, Alternate law.
As you know, during the incident the ACA crew experienced two stall warnings which the PF considered spurious and disregarded. That probably saved his day.
The analysis of this incident, which was published earlier, states that given the configuration, the threshold to trigger a stall warning is AoA = 4.2°.
Question: do you people with flying experience on A330 think that at 4.2° AoA this airplane is so close to max AoA that it is reasonable to throw a stall alarm, especially in the situation at hand ?
