CAN YOU IMAGINE how dependent we have become on computers to do things, and THUS when a NUTTY value comes along the COMPUTER BELIEVES IT AND THEN GIVES UP
NUTTY, as in having a stall warning system that doesn't work when measured airspeed is below 60kts:
If the CAS measurements for the three ADR are lower than 60 kt, the angle of attack values of the three ADR are invalid and the stall warning is then inoperative.
