From some notes of mine.
The AOA input is into the Stall Management and Yaw Damper Computer (SMYD), it only appears to have an effect on the elevator feel when close to a stall. In these circumstances, the SMYD provides an input to the elevator feel shift module which provides 850 psi system A pressure to the elevator feel computer and dual feel actuator. This causes the elevator feel force in the feel and centering unit to increase and to counteract or resist elevator up movement at the control column. Activation of this occurs at an AOA of 8 to 11 degrees depending on flap position.
