Traffic Collision Avoidance System Warning Risk of Transport and Training Aircraft Based on Related Parallel Approaches

In order to ensure the safety and efficiency of the transport and training aircraft when operating on the same airport, the TCAS warning risk when the transport and training aircraft perform related parallel approaches is studied. By studying the TCAS warning logic and process, a flight conflict detection model was established; the movement model of the transport and training aircraft in the related parallel approach was established according to the aircraft approach procedures; combined with the runway parameters and aircraft performance data, the Monte Carlo method was used to stochastically Generate a normally distributed set of initial parameters such as aircraft position and speed; through a large number of calculations, the TCAS warning conditions under the current relevant parallel approach regulations and the smaller interval standards are obtained. The results of the study show that the transport aircraft and training aircraft will not trigger the TCAS alarm when performing related parallel approaches on the five sides under the current regulations; from the perspective of the TCAS alarm, the separation standard for the transport and training aircraft in related parallel approaches can be reduced to 1.8km.
