The A7E/TF41 Engine Monitoring System (EMS) is a derivation of the Inflight Engine Condition Monitoring System (IECMS). The IECMS program was initiated in 1971 under US Navy contract to monitor the Detroit Diesel Allison TF41 engine installed in the US Navy A7E attack aircraft. EMS represents the application of an on-board microprocessor-based system to continuously monitor engine health and output appropriate information. The current EMS configuration is the culmination of several phases of system development and evaluation. Full retrofit of the A7E fleet is planned beginning in 1984. This paper describes the present EMS configuration and discusses program development and accomplishments since the system concept was initiated.
