  • Patent number: 11155360
    Abstract: A method for monitoring at least one engine of an aircraft wherein the aircraft includes a passenger cabin. The method includes a step of acquiring a signal that is at least in part representative of the activity of the engine, using a sensor during a flight of the aircraft, and searching for a defect in the engine by a processing unit using data obtained from the signal. In some embodiments, the sensor is in a mobile device located in the passenger cabin. In some embodiments, the health of the at least one engine uses the signal acquired by a plurality of mobile devices.
