In order to solve the problems faced by the construction and development of aircraft simulation training system and meet the training needs in the new era, a development framework of aircraft simulation training system is proposed based on the collaborative technology of flight simulator brain and cloud edge. The key technologies and difficulties involved in the framework construction are analyzed, and relevant development suggestions are put forward. The analysis results show that the development framework can better solve the problem of simulator network training, and provide support for the development of the new generation of aircraft simulation training system.
