交叉跑道进离场窗建立方法

针对交叉跑道相关运行模式下复飞引起的进离场冲突问题,提出规划交叉跑道冲突全域以保持进近复飞与离场航空器的飞行间隔.将交叉跑道冲突全域分解定义为前窗和后窗,依次建立直接交叉汇聚和非交叉汇聚跑道前窗、后窗的碰撞风险评估模型,并研究跑道交叉角度对侧向、纵向和垂直3个方向以及总体风险的影响程度.选取成都天府机场非交叉汇聚跑道组和美国威奇托机场直接交叉汇聚跑道组为实例进行仿真分析,结果表明天府机场冲突全域的范围为进近跑道入口前11.89 km至入口后6.44 km,威奇托机场冲突全域的范围为进近跑道入口前10.93km至入口后6.85km,将划设的交叉跑道冲突全域与规章中基于时间的尾流间隔约束相比较,可最终确定进近复飞与离场航空器的安全间隔,也可对未来国内交叉跑道构型相关运行模式下的安全间隔提供参考.

A Study of the Method for Establishing Intersecting Runway Arrival and Departure Window

In view of the safety conflict caused by go around on the intersecting runway related operation mode, an entire conflict domain of intersecting runway is designed to keep the flight separation between approach go around and departure aircraft. The entire conflict domain of cross runway conflict is defined as front window and rear window. The collision risk assessment models of the front window and the rear window of the direct and non cross converging runways are established in turn, and then the influence of the runway cross angle on the lateral, longitudinal, vertical directions, and the overall risk is studied. The direct cross convergence runway group of Wichita airport and non cross converging runways group of Tianfu airport are selected as an example. The results show that the entire conflict domain of Tianfu and Wichita airport ranges respectively from 11.89 and 10.93 km before the approach runway entrance to 6.44 and 6.85 km after the entrance. Compared with the time based wake interval constraint in the regulations, the entire conflict domain of the cross runway can finally determine a safe interval between go around and departure aircraft, and can also provide a reference to the separation of the future domestic cross runway configuration under related operation mode.
