Abstract

Time variable and time interval variable were introduced, and nominal separation and collision risk at any time were analyzed. Time interval distribution, flow rate, the proportion of aircraft types and turning angle were determined by using two flight segments at the turning point, and a collision risk model was proposed. With the model, the collision risk of turning air-route was calculated, and the influences of different parameters on the collision risk were analyzed. Analysis result shows that the larger the distance from the initial point of flight segment to the turning point and aircraft rate are, the larger collision risk is. But the larger the minimum time interval at the turning point is, the smaller the collision risk is. It can be seen that the proposed model is reliable and simple.
