飞行计划模块包括飞行计划管理、航迹优化计算、飞行中实时执行等子功能模块。首先研究了飞行计划的人工创建、自动创建、状态管理等功能模块的实现方式；然后研究了水平航迹（水平计划）合成、三维航迹（垂直轨迹）优化和四维航迹生成模块的实现方式；对于飞行计划的实时执行功能模块，研究了由于危险天气、空管限制、飞机构形等因素限制而进行计划偏离、直飞、等待、激活备用计划、航路备降、盘旋等待等功能模块的实现方式：最后以波音737-800飞机的相关数据为例进行了仿真计算，研究结果可为飞行管理系统的研究提供参考。%Flight planning module includes the sub-functions such as flight plan management, flight path optimi- zation calculation, and in-flight real-time implementation. Firstly, how to realize the artificial creation, automatic creation, and state management of flight plans is discussed. Secondly, the realization of parallel tracks combina- tion, three-dimensional trajectory optimization and four-dimensional track creation is studied. For the flight plan real-time implementation module, the realization of such functional modules as flight plan deviation, direct flight, holding, backup flight plan activation, en-route diversion, and circling holding is discussed, which are usually due to dangerous weather, ATC limitations, or aircraft configuration. Finally, the simulated calculation is done based on the data of B737-800 the results can provide a reference for the research of Flight Management System.
