Development of Flight Simulation Technology in CFTE

CFTE's main work for flight simulation has always centred on improving the simulation fidelity, increasing the effectiveness and beneficial results for simulation tests,and establishing the environment of simulation modelling and simulation tests.The paper introduces the general goal, fundomental strategic concept, specific measure and practical activities for flight simulation in CFTE. It describes the development of simulation techniques and simulator facilities,including the developing history, present status and technical level.It also discusses the development tendency,some features and efficiency of flight simulation technology in foreign countries. It gives emphasis to build in-flight and ground simulator facilities in CFTE to suitable for a need of Chinese aviation industry development.
