Abstract: A realtime flight instrument simulation training system was developed. On the basis of allpurpose simulation math model, the intelligent control method and technology were adopted. By comparison with the actual flight data prepared in advance in the repository, the system automatically adjusts the control input, which makes the system error decrease gradually. The math model of gauge transposition was designed and built, which guaranteed the harmony of operation and instrument. It can simulate the instrument flight of all kinds of aircrafts. The experiment data and practice have shown that the simulator has a high efficiency, veracity and real time, which can improve the harmony and instrument flight ability of pilots. It can satisfy the requirement of flight instrument simulation training.
