Onboard Maintenance Systems (OMS) provides a model-based diagnostic approach unlike any other solution on the market. It offers aircraft operators and original equipment manufacturers (OEMs) a quicker aircraft turnaround time and reduces production and lifecycle costs. The primary function of the OMS is to monitor the health of the aircraft (through our aircraft condition monitoring function) and diagnose issues quickly and accurately. Applications: • Continuous monitoring of aircraft avionics during flight • Diagnosis of the root cause fault behind symptoms • Correlation of the fault with flight crew alerts (flight deck effects) • Informs the maintenance crew of the required repair action • Performs applicable testing (built-in test (BIT), ground tests, return-to-service tests)
