摘　　要：针对于性能的导航(PBN)飞行程序运行仿真过程中将面临飞行航段以及航空器的状态不断发生变化问题,提出采用有限状态自动机理论解决这一问题。仿真框架的水平剖面通过ARINC 424中定义的航段类型对具体的程序进行分段建模;垂直剖面通过BADA的性能模型以及提出逆向法计算下降顶点的位置,为水平剖面提供精确的性能及位置参数。获取的仿真航迹数据符合PBN的导航规范及精度要求,可用于进一步的PBN飞行程序的安全风险与噪声评估。As the diversity of PBN flight legs and the states of aircraft are constantly changing during the simulation,the theory of Finite State Machine （FSM） is used to control the conversion and cohesion be- tween different legs and flight states. In the simulation framework, the horizontal profile mainly models the procedure with the specific legs that refer to ARINC 424, and the vertical profile provides accurate per- formance parameters and position for horizontal profile by using the performance model of BADA and the reverse method to calculate the position of the top of descent. The acquired trajectories by simulation cor- respond the navigation specifications and the precision requirements, and can be used for evaluating the security risks and noise of the flight procedures.
