The development of science and technology promotes the development of industrial and the change of idea and thoughts. Combined with the computer technology and information technology development, a lot of scientific technologies achieved huge improvement. In this context, simulation technology has also made a comprehensive and in-depth development, especially in the design and application of the all-digital flight simulation platform. The building of all-digital flight simulation platform has greatly helped pilots' flying in the complex environment, which has important significance to reducing the flight costs, enhancing the pilot combat techniques, etc. In particular, the development and utilization of the UAV will greatly promote the combat capability of the Air Force, and has great significance to enhance the country's military level.
