All PC12 have a very efficient Stick pusher installed.
The Stick Pusher is tested before every flight. If it doesnīt pass the test, the autopilot isnīt working and that is a no go.
The Pusher does a very good Job in preventing the airplane from entering a stall.
I am 6 feet male, 220 lbs and I am unable to overpull the stick pusher.
The Pusher works on 2 independent AOA sources and doesnīt need airspeed info.
If this system had been installed on Airbus, I donīt think the AF accident over the south atlantic would have happened.
