In the whole urban air transportation system,the terminal area of the take-off and landing site is an important link,during which the safety and efficiency of UAV approach and departure are crucial.For this link,a reasonable airspace structure and sequencing strategy need to be designed to ensure the safety and efficiency of UAV approach and departure.In this paper,we consider the approach and depar-ture path constraints from the aspects of airspace design and sequencing strategy,and design the UAV ap-proach and departure program.Firstly,the airspace model of UAV approach and departure is established,and the flight procedure is designed;the first-come-first-served sequencing strategy,the sequencing strategy according to plan,and the honesty principle sequencing strategy are used to carry out simulation experiments and analyze the delay time and model stability to obtain the highest degree of matching be-tween the first-come-first-served sequencing strategy and the model among the three kinds of sequencing strategies.
