The Stall protection system consists of 2 SPMs or Stall Protection Modules and uses the following parameters to calculate when the a/c is near a stall condition:
AoA data
Flap Position
EAS
Engine Torque
Icing Status
Both SPMs are used to calculate the Stick Pusher operating angle using the following parameters:
AoA
Flap Position
EAS
Power Lever Angle
Condition Lever Angle
Icing Status.
The SPMs calculate when to operate the Shaker & Pusher systems and sends a signal to the Automatic Flight Control System to disengage the autopilot, also for Stick Pusher activation it uses an average of the 2 AoA vane inputs.
Stick pusher operates under these conditions
