Huh? How is that?
Stall warning logic is : ring if AoA > limit.
Then a false stall warning implies a false AoA measure IMO.
And a false AoA measure gives a false AoA reading on the AoA meter.
Same source = you cannot cross check.
First, i dont think that the STALL warning is derived from one or all three AOA vanes and not being run through some gizmo until finally used together with some other inputs like speed, loadfactor. configuration, altitude, you name it.
Therefore i have a more simple device in mind like posted above.
It would be most apreciated, if a backup system would not use the same source as the primary system. Schould not be rocket science.
