空中交通管制进近程序间隔安全性评估模型

空中交通的飞行冲突问题日益严重,笔者认为对空中飞行碰撞风险问题研究非常必要,旨在建立进近程序间隔评估模型。通过对影响进近间隔因素的分析确定了各因素对进近间隔的影响程度。应用假设平移法证明了导航台(VOR/NDB)顶空盲区内飞机报告过台位置偏离顶空盲区中心的距离与该距离下报告的飞机数量服从正态分布。应用概率等数学方法计算求得各因素决定的间隔,由各因素间的相互关系确定了模型间隔如何满足各因素确定的间隔。建立了进近间隔评估模型并对模型进行了验证和推广。

Safety Assessment Model for Air Traffic Control Approach Procedural Separation

With the rapid increase of air traffic flow in recent years,fight conflict have become more and more serious.So it is very necessary to make a study about how to avoid flight collision in the air.The purpose of this paper is just to establish a safety assessment model for approach procedural separation.The factors influencing approach separation are analyzed and their influencing degree is determined.It is proved by using hypothesis translation method that the relation between the distance,at which the pilot may report to the ATC(air traffic controller)in the radio blind area center when the aircraft over flying the VOR(Very high frequency omni-directional radio range)/NDB(Non-directional radio beacon),and the number of the reports abides by normal distribution.Then,the separation decided by each factor can be calculated by using the probability and the mathematics methods,thus the general separation decided by this model can be worked out according to the relationship among these factors.The assessment model for approach procedural separation has been tested and extended.
