Water pilot continues below, but a point I've been wondering about for ages.
MCAS winds back after it's done its thing? So little has been made of this - apart from me - that I wondered if I'd misunderstood. However, it seems that if the PF uses the electric trim, this will not happen. Since there was extensive use of the thumb switch trim, I guess this is why MCAS at no stage put things back where it found them. Erm, did it?
What a vital observation.
GordonR carries the logic forward in the next thread.
Doesn't there need to be a *working* AOA sensor that actually provides decreased AOA with the application of stabilizer by MCAS before MCAS will unwind? Why would unwind if it still thinks the AOA is too high?
