As requirements for Flight Control, Fire Control, Propulsion Control and Navigation Systems are developed for future fighter aircraft, reliability, maintainability, availability, redundancy, and survivability become key issues. These systems require dependable and accurate sources of inertial measurement data. The Multifunction Flight Control Reference System (MFCRS) was developed to demonstrate the use of a minimum number of inertial sensors. The MFCRS Program used two extensively modified Ring Laser Gyro (RLG) navigation units to perform the flight control reference and navigation functions on board an F-15 fighter aircraft. An overview is given of the various stages of development that were completed on this program, the lessons learned to date, and what is planned for the future. Evaluation of MFCRS was undertaken to evaluate performance at the system level and evaluate flight control outputs, redundancy management, electronic MRU to MRU alignment, reaction time, navigation performance, performance under vibration, temperature, EMI environments, and operation when integrated with the F-15 Flight Control System. Following the MFCRS laboratory evaluation a ground structural mode interaction test and a two phase flight test program was performed. Subsequent to the successful completion of the phase two flight test evaluation, changes to the MFCRS hardware and software structure, which would improve system performance and expand the MFCRS flight envelope, were identified. Following the laboratory evaluation additional flight testing was planned to verify that the EMFCRS configuration would result in level 1 handling qualities in both supersonic and subsonic flight was well as in tracking of target aircraft. Unfortunately, during ground testing prior to flight, a 22 Hz structural mode interaction was found in the control system pitch channel. The system changes developed during the EMFCRS studies, the laboratory test results, and the aircraft testing are discussed, as well as the follow on development of multifunction system now in process under the name of Ada Based Integrated Controls System (ABICS) Phase 3.
