What about this alternate switching of AoA data and MCAS?
Has the 737m one stick shaker or two independent SS?
Is it that way one AoA drives the shaker, the other one MCAS? Hhmm.
Anyone in the know?
Thx
From the thread on Rumors - (so it must be true
)
Each AOA feeds the control position on its side of the aircraft the side with a bad AOA indicating stall will get stick shaker
Both AOAs feed the ADIRUs - so if the AOA's mismatch the effect is UAS
A single AOA feeds MCAS and this switches one from the other after the squat switch indicates weight on wheels.
MCAS only operates when the aircraft is being flown manually
I am sure people will correct me if that is wrong
