航班改航飞行是空中交通流量管理的重要组成部分,在发生危险天气时可安全有效地为航班选择一条临时航路,提高了空域的利用率,具有广阔的应用前景。针对航班改航路径规划的研究现状做了系统、全面的分析,按改航实施时间的不同将改航路径规划方法分为两类,即飞行前改航路径规划和实时改航路径规划,并分别予以分析和总结。最后,指出了当前研究中存在的问题和未来改航研究领域的发展方向。
Flight diversion Flight is an important part of air traffic flow management. It can safely and effectively select a temporary route for flight in dangerous weather and improve the utilization rate of airspace. It has broad application prospects. A systematic and comprehensive analysis of the status quo of flight diversion route planning is made. According to the different implementation time of flight diversion, the route diversion planning methods are divided into two categories, that is, the route planning before flight change and the route change planning in real time Be analyzed and summarized separately. At last, it points out the problems existing in the current research and the development direction in the field of future research.
