Research on the Application of QAR Decoding Technology in Civil Aviation

The flight data and system parameters recorded in the quick access recorder of civil aircraft have become the basic basis for operation control and flight technology management, and also have a profound impact on the maintenance work. QAR (Quick Access Recorder) is an airborne flight parameter recorder for civil aviation aircraft, which has the advantages of fast transmission, strong timeliness, and convenient extraction. This paper analyzes the experience and methods in actual troubleshooting, extracts the effective information carried by the QAR data, and decodes and analyzes the recorded parameters, which can achieve accurate troubleshooting for aircraft maintenance, while reducing unnecessary maintenance work and component errors. The replacement rate provides strong support and guarantees for aviation safety.
