Abstract: To improve runway utilization, the problem of building runway high-speed exit on old airfield which flight area shape like “目”has been studied systematically. Through analysis the process that airplane taxing in the runway high-speed exit，influencing factors which are distance between the runway and taxi way and between two mid-taxing way are founded. Based on this，the math model which for the distance that runway high-speed exit need is built and limiting condition that is distance along runway is demonstrated，then the curves between airplane taxing speed and distance from the runway to taxi way and runway high-speed exit need are obtained for representative airplane, when degree of runway high-speed exit angle is 30°，45°, and 60°. At last, using the paper’s result, the feasibility of building runway high-speed exit on a certain airfield is analysed, and the rebuilding scheme for runway high-speed exit is put forward.
