Stall warning AoA

RE: Hyperveloce (#4039)

But to get an aerodynamical margin, don't we have to compare the AoA to a threshold/a max AoA ? (what is done in the alpha prot). Shouldn't this max AoA depend on the airspeed/altitude ? (Pitot/static)
The stall warning AoA does have a margin to the AoA corresponding to the stall speed (what you call max AoA). The stall warning AoA is not afffected by airspeed/altitude, weight, loadfactor or airspeed. If erroneous pitot/static produces erroneous stall warning, it's just another fault of the system.
