The invention discloses a flight data decoding analysis method based on the ARINC767 specification. According to the data record characteristics of the ARINC767 specification, an appropriate decoding library is matched for flight data to complete decoding. Users do not need to have an in-depth understanding of the structure of data and the type of a decoding library. The decoding analysis method of the invention will continue trying until the completion of decoding. After trial decoding succeeds, the current configuration will be updated to backend default configuration. For the processing of a large amount of homogenous data, a lot of trial decoding time and manual configuration time can be saved.
