Abstract: The system for collecting and analyzing data relating to safety and comfort criteria of an aircraft comprises an acquisition unit for acquiring basic aircraft information before a flight of the aircraft and values of flight parameters during the flight, the basic information and the flight parameter values forming a first set of digital data, a measurement unit for measuring values of environmental parameters during the flight and for storing, in a suitable digital format, a second set of digital data representative of the environmental parameter values, an analysis unit for analyzing the first and second sets of digital data, and radio communication systems for transmitting sets of digital data between the different units, the system allowing for a rapid collection and analysis of the digital data.

Abstract: An aircraft sound diagnostic method includes a step of measurement of acoustic signals by a plurality of microphones mounted at different positions inside the aircraft, a step of recording of the measured acoustic signals, a computation step which generates a sound mapping on the basis of the measured acoustic signals, a step of comparison of the sound mapping and a reference mapping and a step of transmission of the comparison to a user device. The method makes it possible to track the trending of an abnormal noise or of an abnormal noise level and assist in determining the context thereof. An aircraft sound diagnostic device for implementing the method is also described.
