For the existing flight simulation system can not directly use the real flight training data, lack of multi-angle observation aircraft method and other problems, designed and implemented a set of $\mathbf{B/S}$ architecture based on the flight view restoration system. The system can adapt to different data formats among various aircraft types, pre-process the data effectively, combine with Flightgear flight simulation engine, use JavaScript scripting language for web dynamic interaction, and realize the observation of aircraft flight status from three angles: aircraft, instrument and flight trajectory. The system is tested with real flight training data, and the results show that the system can correctly restore the flight view and restore the animation clearly and smoothly. The system has the characteristics of high simulation, high fluency and high clarity, and has significant application prospects in the field of flight training quality assessment and flight accident investigation.
