F/A-18E/F F414 advanced inflight engine condition monitoring system (IECMS)

The IECMS proven on the F/A-18C/D aircraft has been further developed with expanded capabilities for the F414-GE-400 engine installed in the F/A-18E/F Super Hornet. IECMS combines diagnostic algorithms, engine control system computer/sensors, and airframe computers to process and report real time engine health. These system elements are described with emphasis on the manner in which they are integrated and the benefits to the pilot, maintenance crew, and weapon system readiness. Comparisons between the baseline and advanced IECMS capabilities are presented. Examples are also included of anomalies detected by IECMS during engine ground runs and inflight, along with the resulting maintenance actions/design changes that improved system safety, reliability, and maintainability.
