Three-region airspace FRA division method

Abstract

The invention discloses a three-region airspace FRA division method. According to the method, an FRA basic operation range is defined according to the shape, the size and the position distribution ofa three-region crossing air route in the airspace of China; an FRA flight boundary, an FRA entrance and exit point and an FRA middle airway point are accurately determined by utilizing existing airwaypoints and self-defined longitude and latitude points, and finally, an FRA flight route avoiding a three-region airspace is planned according to actual conditions of airway flight and the activity state of the three-region airspace. According to the method, by research of the three-region airspace FRA division method in the three-region airspace, the airspace utilization rate can be increased, the airspace use flexibility is improved, and a more flexible scheme is provided for flying around in the three-region airspace.

Description

technical field [0001] The invention relates to a method for delineating a "three-area" airspace FRA (Free Route Airspace, free route airspace), which belongs to the field of aerospace technology. Background technique [0002] The "three areas" are collectively referred to as restricted areas, dangerous areas and restricted areas in the air. Forbidden zone refers to the space delineated over important political, economic and military targets of the country, and no aircraft is allowed to fly into the space without special approval in accordance with relevant national regulations; The space used for air-to-air shooting or launching; the restricted area refers to the airspace set up over air routes, important military locations near air routes, weapon testing grounds, and airport flying airspace for aviation units such as aviation units and flight schools. [0003] There are currently many "three areas" in my country's airspace, and the existence of these areas makes the air r...

AI Technical Summary

Problems solved by technology

If special circumstances such as potential conflicts and bird strikes are encountered during flight, the aircraft needs to change its original flight status, and take measures such as acceleration, climb, and yaw according to air traffic control rules. Existence will limit the choice of aircraft, making the overall airspace utilization rate lower

[0004] With the current flying around the "three areas", the layout of the air route is restricted by the restrictive conditions such as the number, shape, and layout of the "three areas", which makes the overall airspace utilization rate low and the flight mode flexibility is low, which leads to Increased flight distance and reduced air transport efficiency
