运输机与四转弯训练机相关进近的TCAS告警研究

Research on TCAS Warning Risk of Transport and Fourth Turn Training Aircraft in Related Approaching

为了保障运输机和训练机能够安全高效地实行相关运行模式,对正在四转弯的训练机与运输机相关进近进行了TCAS告警风险研究。结合TCAS系统告警逻辑,建立了飞机冲突告警模型;根据运输机和训练机飞行程序及运动特点,分别建立了两类飞机在相关进近中的运动模型;结合跑道参数和飞机性能数据,采用蒙特卡洛方法随机生成按正态分布的飞机位置、速度等初始参数集;生成的初始参数代入运动模型,并结合飞机冲突告警模型对现行相关进近规定下以及更小间隔标准下的TCAS告警情况进行仿真实验。研究表明:运输机与四转弯训练机在现行规定下进行相关进近时不会触发TCAS告警;从TCAS告警的角度看,运输机和训练机相关进近时的间隔标准尚有缩减的空间,最低可缩减至3.4 km。

In order to ensure that the transport aircraft and the training aircraft can safely and efficiently implement the relate dapproaching,a TCAS warning risk study was carried out in the approaching of transport and the fourth turn training aircraft.Combined with the alarm logic of the TCAS system,an aircraft conflict alarm model is established.According to the flight procedures and motion characteristics of the transport aircraft and training aircraft,the motion models of the two types of aircraft in the related approaching are established respectively.Using Monte Carlo method randomly generates initial parameter sets such as aircraft position and speed according to the normal distribution.The generated initial parameters are substituted into the motion model,and combined with the aircraft conflict warning model,the TCAS warning situation under the current relevant approach regulations and smaller separation standards is carried out.The research results show that TCAS warning will not be triggered when transport aircraft and fourth turn training aircraft conduct related approaching under the current regulations.From the perspective of TCAS warning,there is still room for reduction in the separation standards of transport aircraft and training aircraft during related approaching,and the minimum can be reduced to 3.4 km.
