In order to guarantee the rationality of the high-speed exit settings, the problem how to set the high-speed exit is studied systematically from the point of increasing the utilization ratio of airfield high-speed exit。 Through the analysis of the characteristics of aircraft landing running distance, the rule is found that the main factors impacting on the high-speed exit location are of normal distribution. Aimed at the high-speed exit used by single type and multi-type of airplanes concepts of utilization ratio and comprehensive utilization are constructed, and optimization models of high-speed exit location are built based on the concepts of both the utilization ratio and the comprehensive utilization. Based on the optimization models, the high-speed exits location for a typical combination of airplanes are optimized, and the steps how to determine the location of high-speed exits based on utilization ratio are summarized. The method proposed in the paper is of an important reference value to the setting of high-speed exit in military airfields.
