AEM Acoustic Engine Monitor: transforming raw sound data into Predictive Maintenance Alerts

The AEM uses a microphone array and accelerometer sensors — without any engine modification — to continuously capture the acoustic signature and vibration patterns of the engine and propeller in real time. Proprietary machine learning models, trained on thousands of hours of aviation flight data, analyze these acoustic signatures to detect subtle anomalies that indicate early-stage mechanical wear — often up to two months before a critical failure would become evident through traditional inspection methods.

Yes. AOG prevention is the primary value proposition of the AEM. By detecting piston engine degradation up to 2 months early, the AEM gives maintenance teams and fleet managers the advance warning needed to schedule inspections during planned downtime rather than reacting to emergency groundings. A single avoided AOG event typically justifies the full cost of the system many times over.

No. The AEM requires zero engine modifications, zero internal sensors, and zero STC. The device is mounted in the cabin and listens to the engine acoustically — it is a fully removable, plug-and-play device compliant with EASA CS-STAN 061.

This makes it one of the most accessible aircraft engine monitoring systems available to general aviation operators, flight schools, and CAMO organizations.

Yes, the data collected by the device can be accessed through dedicated software applications, which can be used independently without requiring access to specific modules of The Manager© .

The AEM can be installed on both airplanes and helicopters. Installation can be performed by any qualified CAMO or approved Maintenance Organization, ensuring broad compatibility across any type of aircraft.

Yes, you can choose either of the two devices based on your specific needs. AEM is typically selected when the focus is on engine performance monitoring, while IFU is preferred for detecting and analyzing flight maneuvers.
