Our simulation system was implemented based on flight simulation model. In order to enhance system' s reliability and improve data structure, a new data structure and algorithm of curve generated were designed to draw real - time curve to achieve the visual observation of the data. Combined with characteristics of flight simulation and by incorporating MapX component technology in the system, the traditional electronic map display was improved and achieved real-time flight track map observation. Experimental results show that this system can not only supply real-time observation of the flight parameter, but also analyze system errors effectively. It can be used to validate the correctness of flight simulation system and other related simulation systems.
