I see now that stall recovery was impossible.This aircraft wasnt at the approach to stall(like we do in the sim-we recover at stick-shaker onset);the stall was fully developed and so it had to be unstalled first before recovery procedure.To fly the recovery procedure(20 deg) with the speed that low and with that ROD needs a rocket.WE dont have the data in front of us,I dont think we can really appreciate just how much altitude loss was necessary to first "unstall"(speed trend out of red band) it before the recovery procedure was flown.We dont do this in the simulator because the assumption is no pilot would let such a situation develop at altitude never mind 500'.To go from -4000fpm with Vref-40 straight into the stall recovery procedure needs a rocket.I see that now.

AT computer is fed by RA#1 or both RA#1 and RA#2 depending on software update.There are diagrams in the AMM showing this.
