Flight simulator data package flight test is used to obtain flight test data required for development and qualification of flight simulator, involving multiple flight test subjects. In order to improve the efficiency of flight test and reduce the cost of flight test, the optimization and combination method of flight simulator data package flight test and type flight test were studied. By analyzing requirements of the flight simulator development progress, type flight test plan, type configuration inplace plan, and flight test requirements and other elements of each flight test subject of flight simulator data package flight test and type flight test, different optimization and combination principles were proposed in the flight test subject analysis stage and flight test point analysis stage, including flight test method similarity principle, subject category similarity principle, and the principle of pretest meeting and the principle of considering configuration requirements. Four optimization and combination methods were given, which were namely direct combination, continuous combination of flight test points, configuration change combination and sortie combination. The flight test phase of flight simulator data package which was suitable for the optimized combination methods were given. The optimization and combination method presented in this paper has been applied in the flight test plan of the actual type flight simulator data package, which can reduce the quantity of flight test missions.
