Abstract：In order to realize the fusion operation of the terminal area of UAV and general aviation aircraft,a collision risk model based on CNS position error distribution with Gaussian distribution is adopted for the difference of communication,navigation and surveillance performance between UAV and general aviation aircraft:the UAV is considered as a mass point,the UAV collision protection zone is superimposed with the general aviation aircraft protection zone,and different combinations of models are selected as Matlab software is used to simulate the collision risk probability of different combinations of aircraft types operating on the same route at different flight intervals during the fusion of terminal areas,and to optimize the collision risk model by considering various factors of human,aircraft,environment and control.Taking the 5×10-9 safety target level proposed by ICAO as the standard,CESS-NA172R,SR20,TW312 and TW328-A are selected as the combinations to study the operation interval required to meet the ICAO collision risk target level.The simulation results show that the above combinations meet the target level proposed by ICAO when the longitudinal interval of terminal area fusion operation is greater than 5.3 nautical miles.There are few papers that combine CNS and human,aircraft,environment,and control aspects to study the longitudinal collision risk of terminal area fusion operation.In the fu-ture,more factors including CNS can be considered for further research on the fusion airspace capacity and other aspects using this collision model.
