SAS Limitations

Parent Previous Next

Under conditions of a single system APU failure or failure of either the roll or yaw functions, lateral directional control problems can be encountered in the speed range of Mach 2.5 to 6.0 and at angles of attack in excess of 8 degrees nose up with the ventral installed. Should control problems be encountered under these conditions, the following recovery techniques should be employed:


  1. Reduce angle of attack.


  1. Extend speed brakes.


  1. Jettison ventral if below the airspeed limit for jettisoning the ventral.



Note: If the ventral is not installed, the failures noted previously will not seriously affect airplane controllability.
