An overview of a fly by light yaw control system which uses the DISCUS (Digital Self healing Control for Upgraded Safety) computing system, its implementation, and the results of flight testing are provided. The objectives of the program described were to utilize innovative technologies in signal transmissions, actuator systems, and redundancy management and to test a single axis feed forward controller with 100 percent actuation accuracy. Plans to expand DISCUS to build a 4 axis control system are outlined. Details of the DISCUS system concept, computer architecture, and data processing concept are given. The integrated fiber optic intelligent actuator has command input via fiber optical cables. The main goals in the design and evaluation of the yaw controller were to improve the helicopter's handling characteristics and to expand its range of operation. These goals and the flight testing of the yaw controller are addressed.
