In order to meet the requirements of PBN operation for domestic civil aircraft and solve the deficiencies of the existing PBN departure procedure trajectory simulation tools in terms of flexibility,universality and user experience,this study proposes a method for departure procedure trajectory simulation based on PBN technology.By analyzing the characteristics of PBN technology and the trajectory termination code,combining the transition route algorithm and the departure kinematic model,the study constructs a complete simulation calculation model and develops a simulation tool based on Fortran and C#.The results show that the method is able to generate continuous smooth trajectories in line with standard instrument departure procedures and the simulation results are highly consistent with the actual charts,which verifies the correctness and versatility of the algorithm and it is applicable to the simulation needs of departure procedures at a variety of airports.
