Functional sector partitioning method for airspace of civil aviation multi-airport terminal area

Abstract

The invention discloses a functional sector partitioning method for airspace of a civil aviation multi-airport terminal area, belonging to the sector partitioning field of airspace of an airport terminal area. The method comprises the following steps: firstly, establishing a model for calculating the number of sectors based on controller workload statistics, thus determining the number of the sectors; and then dividing an air route into a plurality of units according to the in / off airport air route information of the airspace of the terminal area, and determining the control load occurrence point of each unit; establishing a sector optimizing model based on separation of the in / off airport air routes; determining a primary sector partitioning scheme by using a random optimizing algorithm;and finally determining the final sector partitioning scheme through the decision of control specialists, and verifying the final scheme. According to the invention, the control workload of each sector controller is balanced, thereby reducing the workload of controllers during sector transfer, reducing the difficulty of control allocation and ensuring the operation safety of airspace.

Description

technical field [0001] The invention relates to a method for dividing airspace sectors in an airport terminal area, in particular to a method for dividing airspace functional sectors in civil aviation multi-airport terminal areas under the separation of entry / departure routes, and belongs to the field of airspace sector division in airport terminal areas. Background technique [0002] With the growth of air traffic flow and the acceleration of airport construction process, the density of airports in some areas of our country has increased, forming complex civil aviation multi-airport terminal areas. The airspace of the terminal area has the characteristics of complex entry / departure route structure, high flight flow, and heavy control workload. The sector structure has always been a difficult problem to be solved by the civil aviation management department. [0003] In the past, the sector division method of the terminal area was based on the geographical distribution of th...

AI Technical Summary

Problems solved by technology

For some terminal areas with large flight traffic, separated arrival / departure routes, and dense control load, the application of this sector division method in the airspace of civil aviation multi-airport terminals has the following problems: First, an arrival / departure route needs to be crossed Multiple sectors, queued incoming or departing aircraft flows through these sectors in turn, the controllers in adjacent sectors need to issue handover control instructions, which increases the workload of controllers; second, in the case of large flight traffic, In these sectors, there are often cases of cross-operation and altitude occupancy of arriving and departing aircraft, which require simultaneous control and deployment. The types of control workload are complex and the workload is heavy, which is likely to cause erroneous and missing control instructions, resulting in potential safety hazards. ; Third, due to the complex types of control work, the control efficiency is low, and it is easy to cause flight delays and reduce the capacity of the terminal area sector
