Embodiment Construction

[0021] The method of the present invention will be further described below.

[0022] The present invention is mainly aimed at carrying out longitudinal flight conflict risk analysis in the airspace of a large civil aviation busy airport terminal area, and the specific steps are as follows:

[0023] Step 1: Construct a joint simulation platform for airspace and ground in the terminal area of ​​the airport to be evaluated.

[0024] Using the "Domestic Aviation Data Collection" manual, visit the regional control center, approach control room, and tower control room responsible for the airspace control activities of the airport to collect materials, and use Delphi software development on the GIS (Geographic Information System, Geographic Information System) platform The joint simulation platform of the airspace and ground in the airport terminal area constructs the airspace structure of the airport terminal area, the entry and departure routes, and sets the entry and departure poi...

Abstract

The invention discloses a computation method of maximum longitudinal flight conflict risk of airport airspace, belonging to the field of flight safety analysis of airport airspace aircrafts. The method comprises the following steps of: firstly constructing a combined simulation platform of airport terminal area airspace to be estimated and the ground; acquiring annual takeoff and landing fight data, and predicting the annual flight flow of takeoff and landing fights in the airport airspace in an estimation year; analyzing time and space distribution characteristics of the traffic flow of the airport airspace to obtain an average daily maximum hour flow; and finally calculating the risk probability of the maximum longitudinal flight conflict according to the probability of the violation ofthe longitudinal flight safety interval standard of the terminal area airspace. The invention provides data support for airport airspace safe operation analysis and promotes the construction of the airport terminal area airspace.

Description

technical field [0001] The invention relates to a method for calculating the risk probability of the maximum vertical flight conflict in the airspace of an airport terminal area, and belongs to the field of aircraft flight safety analysis in the airport airspace. Background technique [0002] A busy airport refers to a large airport with an annual passenger throughput of more than 30,000,000 and an annual flight number of 240,000; a flight conflict refers to an aircraft flying in the air, at a certain time, the distance between two aircraft in three directions is less than interval standard. Aircraft flow in the terminal area of ​​a busy airport is strictly in accordance with the arrival and departure routes and procedures, and there is no need to consider the risk of conflict in the horizontal and vertical directions. Therefore, the International Civil Aviation Organization has given a minimum vertical separation standard of 3nm in the terminal area, which is 1.5 minutes. ...
