AOA

R1:

GY earlier posted that stall warning was triggered depending on, amongst other things, F/CTL law. Is it the case that stall warning is NOT inhibited below 60kts IF you're flying anything other than normal law?
That's not mentioned in the books !!!

Vane resolver sin and cos is input for ADR, ADR generates AOA from this input if CAS =>60 Kts if not AOA=0 and NCD. This is ADR output fed into the PRIMS/SECS and FWC.
