So we're at twice his target FPV attitude and the plane's barely flying - AOA barely below stick shaker. CKA - "no, no. Keep the FPV at X". Tiniest reduction in back pressure results in instantaneous stick shaker (anyone doing a high AOA knife fight know's what I'm talking about). Unload, go back to twice his target FPV attitude(double wasn't a goal, just what was required to make the plane fly), and we eventually recover.






wilyflier - That's a text mistake.


I meant "tiniest INCREASE in back pressure results(resulted) in instantaneous stick shaker". That was in the 777 simulator.






Fighters don't have stick shakers but it was common to be at the edge of the stall/buffet with in high AOA maneuvering. So it was common to be at the ragged edge of the airflow separation(non FBW a/c) during high AOA maneuvering. Some a/c had an aural tone or you'd have to feel the change in airflow and the resulting change in a/c buffeting "seat of the pants" flying.
