Research On Optimization Of High-altitude Sectors Of Chengdu New Airport Based On Air Traffic Complexity

In order to ensure that after the Chengdu new airport is put into operation,Chengdu highaltitude control area can successfully cope with the pressure of air traffic control caused by the increase of flight volume,accelerate the orderly circulation of air traffic,and reduce the operational risk of the overall Chengdu high-altitude control area in the future,this paper adopts the method of air traffic complexity to optimize sectors based on the objective airspace structure,flight dynamics and other established conditions The research provides a theoretical basis for sector adjustment of Chengdu air traffic control airspace.First of all,this paper analyzes the adjustment of Chengdu high-altitude air route after the completion of Chengdu new airport,collects relevant business data of Chengdu airport,and predicts the flight volume of Chengdu in the future.Secondly,the influencing factors of air traffic complexity are combed from the aspects of personnel capacity,facilities and equipment,and environmental conditions.By using AHP,the main influencing factors and their weights are obtained,and the mathematical expression of influencing factors is established.Finally,a sector optimization model based on air traffic complexity is constructed.Based on the relevant data of southeast Chengdu airspace,a two-dimensional planar sector optimization scheme is obtained by using the growth algorithm optimization model based on complexity.Then,based on the plane optimization scheme,the sector optimization results of 3D space are formed.According to the simulation results,quantitative analysis is carried out before and after the optimization,and the critical value of airspace complexity is obtained with the idea of sector capacity to ensure that the optimization scheme can be used in the actual control work,and then the effectiveness of the method and the rationality of the optimization scheme are verified.
