Abstract

The invention discloses a method for evaluating the collision rate of aircraft continuous descent, which comprises the following steps: S1, determining the arrival rate of aircraft, the number of aircraft and the type of aircraft in the scene to be evaluated; S2, according to the type of aircraft, calculating the vertical S3, enumerates all aircraft pair combinations; S4, according to the vertical continuous descent flight path, respectively calculates the relationship curves between the travel time and travel distance of the leading aircraft and the trailing aircraft in the aircraft pairing, and calculates the The collision rate of the aircraft pair; S5, calculate the continuous descending collision rate of all the aircraft pairs in the scene to be evaluated. The aircraft continuous descent collision rate evaluation method provided by the present invention is realized based on the idea of ​​aircraft pairing, and can calculate the vertical continuous descent track of the aircraft according to different descent conditions, and use the track data to estimate the collision rate in the terminal area descent stage. The present invention also discloses a device for realizing the above evaluation method.

Description

technical field [0001] The invention relates to a method for evaluating the collision rate of a continuous descent of an aircraft, and at the same time relates to a device for realizing the method for evaluating the collision rate of a continuous descent of an aircraft. Background technique [0002] Approach refers to the process in which the aircraft is aligned with the runway when it descends. In the approach phase, to adjust the altitude of the aircraft and align it with the runway, so as to avoid ground obstacles, the pilot must concentrate on the operation accurately. Recently, there are strict standards and operating procedures. The continuous descent approach (Continuous Descent Approach / Arrival, CDA) used by the aircraft during the descent can reduce fuel consumption, reduce exhaust emissions, and reduce noise pollution. However, during this process, the flight accuracy is difficult to control because the aircraft descends with idle thrust. In order to ensure flight...

Problems solved by technology

However, during this process, the flight accuracy is difficult to control because the aircraft uses slow thrust to descend. In order to ensure flight safety and improve flight efficiency, the air traffic control system (ATC) needs to reasonably control the safety risks during the descent process.

[0003] In the existing research, the collision rate evaluation of aircraft is mainly aimed at the cruising process or the traditional ascending and descending process, and the safety evaluation work for the continuous descending and arriving procedures is relatively scarce.
