摘要
针对危险天气条件下进场航空器的改航路径规划问题,利用栅格法构建终端区空域模型,从静态和动态2个方面提出危险天气飞行限制区(flight forbidden area,FFA)的划设方法。在引入自适应扩展节点的概念并优化代价函数的基础上,基于A*算法分别构建静态和动态条件下的改航路径快速规划模型,实现了在危险天气下改航路径的快速、合理规划。以厦门终端区为例的仿真实验表明,该方法在合理规划改航路径的同时,减少了计算复杂度,提升了计算效率,为有效利用空域资源、减少航班延误提供了技术支持。
Reroute planning method of arrival flight under hazardous weather conditions was presented.The airspace model of terminal area was introduced based on grid map method.The division method of flight forbidden area(FFA)under hazardous weather was proposed from static and dynamic aspects.Based on the adaptive expansion and cost function optimization,the fast planning method based on A*algorithm was established under state and dynamic conditions respectively,to accomplish the right reroute planning quickly.Xiamen terminal area was taken as an example,and experimental results show that the proposed method can generate optimal route,reduce computation complexity,and improve computation efficiency.The proposed method can make good use of the surplus capacity of airspace to reduce flight delays.
