Animation and Decoding of EAFR Data Downloaded of C919 in Development

C919 is a new generation of large passenger aircraft with China's proprietary intellectual property rights. In order to meet its flight operation supervision, unsafe incident analysis, accident investigation and other needs, Based on ARINC specifications 664 and 767, this paper focuses on EAFR data downloading and decoding, animation model driving, flight trajectory calculation, audio and video synchronization and other technologies research of C919 aircraft. The development of EAFR data downloading device, EAFR decoding program and data correction algorithm based on XML-Formatted FRED file, and the C919 flight data animation are realized. The research results have been well applied, effectively controlling the operational risks and flight safety of C919 aircraft in the future, and thus improving the flight quality monitoring level of domestic civilian aircraft in CAAC.
