Design of general aviation flight path evaluation and optimization platform based on KML file

为提高通用航空飞行的安全性、经济性,设计并实现一套通航飞行计划路径评估与优化平台。通过解析飞行计划获得用于优化飞行路径的基本数据,利用复杂多约束A*算法优化飞行路径,评估优化前后飞行路径并实现评估数据可视化,使用读写KML文件的方式传递和保存数据,将Google Earth嵌入软件平台作为地理信息系统,通过载入KML文件实现飞行路径和评估参数的可视化显示。测试结果表明,采用该方法设计和实现的通航飞行计划路径评估与优化平台可优化出更满足通航飞行需求的飞行路径。

A general aviation flight plan path evaluation and optimization platform was designed and implemented to improve the safety and economy of general aviation flight.The flight plan was parsed to get basic information for optimizing the flight path.The A star algorithm in complex multi-constrains conditions was employed to optimize the flight path.The optimized and the original flight path were evaluated respectively and related data were visualized.Data were transferred and saved through reading and writing KML files.These KML files were transferred to Google Earth,which was used as a GIS,to achieve the three-dimensional visualization of the flight path.The test results show that the flight path planning and optimization platform designed and implemented using the proposed method can optimize the flight path which further satisfies the general aviation flight demand.
