Abstract：With the rapid development of general aviation,the number of navigable aircraft continues to increase,and the lim-ited airspace capacity increases the operational risk of air traffic.Therefore,assessing aircraft collision risk is crucial.This article es-tablishes an improved Event collision risk model for cross flight routes at different heights based on the concatenated pyramid colli-sion box,and analogically deduces the collision risk of cross flight routes at different heights based on ellipsoidal collision boxes and cylindrical and rectangular combination collision boxes.Afterwards,the generalized Pareto distribution is used to calculate its later-al overlap probability.Finally,two types,Cessna 172 and Yun 5B,are used as examples for calculation and compared with other models.The results show that the collision risk value calculated by the proposed model in this paper is the smallest,and it has high-er accuracy while meeting the safety target level.
