A C-11B Instrument Flight Trainer was converted into a variable stability flight simulator. The original frame, cockpit, controls, pneumatic system and instruments were utilized as well as certain other necessary components. The original aerodynamic and engine computers were removed, a new instrument drive system was designed and a hybrid computer was programed to solve the equations of motion. The cockpit controls supplied the inputs to the computer which in turn supplied the outputs to the various instruments through their respective drive systems. The computer program may be quickly changed to simulate the aerodynamic characteristics of almost any single engine jet aircraft, or the parameters of a specific aircraft may be varied to investigate their effects on flying qualities.
