Research on Collision Risk for Paired Approach Based on Fault Tree Analysis Method

配对进近是提高近距平行跑道容量的有效方式,对配对进近的碰撞风险的研究显得尤为重要。首先对影响配对进近碰撞风险的因素进行了分析,给出各影响因素的概率分布;然后根据事故树分析法,在对影响配对进近碰撞风险因素的分析基础上建立了配对进近碰撞风险事故树;再通过计算最小径集、最小割集和结构重要度来定性分析了事故树中各个基本事件对配对进近碰撞风险的影响程度;最后对配对进近碰撞风险事故树进行了系统特征整体分析。

Paired approach procedure is an effective way to increase the capacity of closely spaced parallel runways, research on collision risk in paired approach is very important. Firstly, the influencing factors of the collision risk in paired approach are analyzed, and given the probability distribution for each factor. Secondly, according to the fault tree analysis, paired approach collision risk fault tree is built. Thirdly, influence degree of the various basic events in the fault tree is qualitative analyzed by calculating the least path set, minimal cut sets and the structure importance. At last, the system characteristics of collision risk fault tree is overall analyzed.
