Failure of one system does not affect the operation of the other system, which is adequate to maintain attitude control. However, control will be at a reduced rate. Refer to "Ballistic Control System".
Note: At the time of publication, ballistic control for rocket airplanes was still not supported in either Microsoft® Flight Simulator X or Lockheed Martin® Prepar3D®. Consequently, the BCS and RAS controls and switches in the X-15A-2 SE do not perform any simulator function in this software version, other than being animated to simulate BCS and RAS-related procedures.
