Embodiment Construction

[0105] The present invention will be further described below in conjunction with the accompanying drawings.

[0106] Such as figure 1 The approach efficiency evaluation method based on the real-time control pressure in the terminal area includes the following steps:

[0107] Step S1, acquiring initial data of the integrated flight track of the aircraft; the initial data includes radar track data and Automatic Dependent Surveillance-Broadcast (ADS-B) data.

[0108] Step S2, for the radar track data described in step S1, use the Cat-062 standard analysis to obtain the original data; for the ADS-B data described in the step S1, use the 1090_ES standard analysis to obtain the original data.

[0109] Among them, the Cat-062 standard is used to analyze and obtain the original data, and the specific method is as follows:

[0110] Constitute a header block (SHB), an interface description block (IDB) and several enhanced packet blocks (EPB) into a data part; identify the SHB in the d...

Abstract

The invention discloses an approach efficiency evaluation method based on instant control pressure of a terminal area. The method comprises the steps of obtaining aircraft trajectory data; adopting acorresponding standard protocol to analyze and obtain original data; preprocessing analyzed data; constructing a dense time sequence, capturing the number of flights in the instant terminal area to represent the instant control pressure, and obtaining corresponding flight key information; carrying out flight sample deduplication on the repeated flights forming the same instant control pressure; analyzing the terminal area approach control efficiency by using descriptive statistics and inference statistics methods; according to the invention, the terminal area approach flight quantity is acquired through the dense time sequence, the terminal area instant control pressure is described, and the terminal area approach control efficiency can be more objectively reflected.

Description

technical field [0001] The invention relates to the technical field of air traffic control efficiency evaluation, and mainly relates to an approach efficiency evaluation method based on real-time control pressure in a terminal area. Background technique [0002] With the continuous development of China's economy, the demand of the air transport industry is increasing day by day, and the increase of demand will inevitably arouse the urgent demand for the improvement of the service quality of the civil aviation transport industry. The terminal area is the converging area of ​​incoming and outgoing traffic flow. It has the characteristics of complex route structure, dense traffic activities, frequent flight conflicts, and narrow maneuvering space. Therefore, the terminal area has always been the bottleneck for improving the efficiency of air traffic operations and the improvement of service quality. [0003] In view of this, civil aviation developed countries and institutions h...
