Abstract: In view of the problems of traditional military aircraft training system,such as low degree of automation,single training mode and unsatisfactory training effect,the characteristics of training support mode in combat environment are analyzed by means of information technology,virtual reality and digital simulation. The training system of military aircraft is constructed by analyzing the technical links of training needs analysis,curriculum design,training system development,evaluation and verification. The training technology system is verified and optimized through the first training of some military transport aircraft. The results show that the training system is reasonable and advanced,and can be close to the fight environment extremely. The training system can cover 97 percent of the fight tasks and 100 percent of the training missions,and can meet all the teaching functions of training required. The training system and new training model can be widely used for training of weaponries in China,which has great significance and far-reaching military significance to improve the safety and combat readiness of our military equipment.
