摘要
为给雷达引导提供辅助决策,设计雷达引导进场路径规划模型。结合空域结构、管制工作习惯和相关规定,提出雷达引导常规路径概念。用线性拟合方法对历史飞行轨迹、标准进场、进近程序进行数据分析,生成雷达引导路径。利用双流国际机场20右跑道标准进场程序、历史飞行轨迹进行验证,模型规划路径均符合航空器飞行性能、间隔标准和管制规则。使用规划路径引导46架航空器仿真进场降落,与历史数据相比,平均飞行时间减少9.1%,平均飞行距离减少8.52%,降落总用时间减少19.83%,飞行拐点减少24.93%。分析结果表明,利用规划路径进行雷达引导能有效减少空中延误,减轻管制员工作负荷,增加机场跑道使用率。
The radar vectoring approach path planning model was designed to provide radar vector with decision-making assistance. Firstly, taking airspace structure, controlling habits and relevant regulations into account, the concepts of radar vectoring path were proposed. Moreover, data of historical flight path, standard arrival and approach procedure were analyzed by using the method of linear fitting, and regular path was produced based on those results. Regular paths are generated in CTU and are veri- fied with standard terminal approach route of 20R runway and historical flight path of CTU, and the results indicate all of the generated paths satisfy historical flight path, aircraft flight performance, separation standard and control regulations. In simula- tion, 46 flights are guided to arrive using the planned path, comparing with historical data, average flight time, average flight distance, total landing time and flight inflection point are reduced by 9.1 %, 8.52 %, 19.83 % and 24.93 % respectively. Analysis shows radar vector with planned path can effectively mitigate air traffic delay, controller＇s workload and also increase runway utilization.
