摘　　要：配对进近模式可以显著提高近距平行跑道的利用率,科学合理地计算配对进近安全区的安全前界对保证配对进近的安全运行尤为重要。针对配对进近过程中前机发生错误进近侵入后机航向道的情况,考虑了后机是否避让的两种行为选择,并融合了风速、侵入角度、避让角度、反应时间等相关参数建立了基于两机位置的运动轨迹模型。通过对两机运动过程进行蒙特卡洛仿真,分析不同参数变化时后机需要保持的最小安全前界。以B737和B747作为配对前后机为例进行方法实证,实验结果表明:随着前机入侵角度增加,不采取避让时,不同机型组合中的后机分别需在FAF点保持430 m、423 m和646 m的最小安全前界;采取避让时,整个进近过程中分别需要保持249 m、268 m和379 m的最小安全前界。The paired approach mode can significantly improve the utilization rate of closely spaced parallel runways.It is particularly important to scientifically and reasonably calculate the safety front boundary of the paired approach safety zone to ensure the safe operation of the paired approach.In this paper,in view of the heading path of the trail aircraft invaded by the wrong approach of the front aircraft during the paired approach process,the two behavior choices of whether the trail aircraft avoids collision or not are considered,and the motion trajectory model based on the position of the two aircraft was established by integrating the relevant parameters such as wind speeds,invasion angles,avoidance angles and reaction times.Then,Monte Carlo simulation was carried out to analyze the minimum safety front boundary that the trail aircraft needs to maintain when different parameters change.Finally,the proposed method was illustrated by the examples of B737 and B747.Experimental results show that:with the increase of the intrusion angle of the lead aircraft,when avoiding behavior is not adopted,the trail aircraft in different combinations should maintain the minimum safety front boundary of 430 m,423 m and 646 m at the FAF point respectively.When avoiding behavior is adopted,the minimum safety front boundary of 249 m,268 m and 379 m should be maintained during the whole approach.
