Problems solved by technology

Unlike en-route controllers, approach controllers generally do not issue altitude clearances when they space air traffic in accordance with instrument flight rules (IFRS), so conflict detection automation cannot obtain the altitude at which the aircraft will level off
This uncertainty increases the false alarm rate
requiring terminal area controllers to issue altitude clearances would increase approach controller workload

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention discloses a conflict prediction method under the altitude restriction of approach control airspace, comprising the following steps:

[0034] Step 1. Extract aircraft flight intention information: associate with the ATC automation system in the approach control area, retrieve and analyze its internal nominal track information, area navigation information, standard instrument approach and departure procedure information, flight plan information, and altitude restriction information or other relevant information;

[0035] Step 2. Determine the horizontal track and velocity profile: Based on the above-mentioned prior flight intention information, screen the relevant aircraft involved in the approach airspace segment, analyze the horizontal tra...

Abstract

The invention discloses a conflict prediction method under approach control airspace height limitation, which comprises the following steps: a, extracting flight intention information of aircrafts; b,determining a horizontal track and a speed profile; c, displaying a trajectory profile; d, setting an early warning advance period; e, setting a conflict alarm threshold; f, designing a conflict detection method; g, correcting error; and h, acquiring and displaying conflict detection maps. According to the invention, automatic conflict detection for the approach control airspace is realized, andthe workload of approach controllers is reduced.

Description

technical field [0001] The invention belongs to the field of aircraft conflict prediction in the air traffic approach control stage, and in particular relates to a conflict prediction method under the height limit of the approach control airspace. Background technique [0002] The rapid growth of China's air traffic and the increasing busyness of the approach airspace of the airport have led to the automatic conflict detection of the approach airspace becoming a focus of attention. [0003] While maintaining the average early warning lead time at an acceptable level, the false alarm rate of approach airspace conflict detection is reduced on the premise of not missing the detection of actual conflicts. The conflict warning (CA) function of the existing air traffic control automation system has a high rate of false alarms, which will affect flight safety. Therefore, an automated tool with high reliability for aircraft conflict prediction in the air traffic approach control ph...
