The flight deck effect is that the pilot will find that as AOA increases, the airplane has and ever increasing tendency to lower the nose to recover. Keep in mind that the stick shaker will also activate giving the pilot both auditory and tactile cues that AOA is above the normal range. Once AOA has dropped below the activation point, MCAS will remove the stabilizer increment that it has inserted. If a maneuver to higher AOA is started from a trim point at a lower, more normal AOA, MCAS will run the stabilizer nose down to aid in recovery and then once recovered to lower AOA will run the stabilizer back nose up so that it ends up close to where it started with the airplane back in trim at the condition from which it started the maneuver.
What would be the "steep turn" envelope of the MCAS? Would 250KIAS and 45 degree bank trigger it. Or min clean and some other angle of bank?
