The stall inhibiting circuit subtracts a portion of the pilot command signal proportional to angle of attack above a threshold determined by flap position. The threshold is higher with flaps down due to added lift which increases the stall boundary. Pitch rate signals are added to the angle-of-attack signals to provide stall inhibit anticipation during rapid maneuvers.
Elimination of Steady-State Sideslip - A circuit was added to reduce uncommanded and persistent sideslip (due primarily to rudder linkage friction or hysteresis) during supersonic flight and following a maneuver. The combined lateral acceleration and yaw rate sensor feedback voltages are compared with the rudder trim position and the combined output is used by the Proportional plus Integral (P + I) circuit to apply rudder surface deflection in a direction to eliminate the sideslip. With a maximum authority of 3.75 degrees rudder, pilots can expect the ball to be pretty well neutral during flight.
