Japan Aerospace Exploration Agency (JAXA) and Japan Airlines International (JALI) have developed a flight data visualization program called DRAP (Data Review and Analysis Program) to enhance aviation safety. DRAP generates three-dimensional animations including a cockpit view, god's-eye view, flight instruments, etc. using flight data recorded by on-board flight recorders (ex. QAR: quick access recorder). It was designed to enable a pilot to improve his/her flight skills by reviewing his/her own flight as part of flight data analysis program activities such as FOQA (Flight Operational Quality Assurance) or DFOM (Daily Flight Operation Monitoring). This paper describes DRAP development and the results of evaluations performed by major Japanese airlines.
