Abstract: With the development of commercial aircraft, the demand of high-level flight simulator will increase. In addition to development and production, qualification test is a key link to ensuring the quality of simulator. Visual system plays an important role of flight simulator. In order to meet the requirement of qualification from CAAC, visual objective test based on main qualification test guide of flight simulator was developed. It is very significant that test requirements, test theory and test methods of visual objective test item were researched deeply, including transport delay, field of view, system geometry, surface contrast, brightness, surface resolution, light point size, light point contrast and visual ground segment, which have reference value of testing other flight simulator.

Key words: high-level flight simulator, visual system, main qualification test guide, objective test item
