Research Of En-Route Capacity Evaluate Besed On Aircraft Trajectory Characteristic

With the rapid development of air transportation industry,the airspace of our country become more and more crowded.How to increase the utilization rate of airspace to contain more aircraft in limited airspace is the problem to be solved urgently.As the minimum component unit of airspace,accurate assessment of route capacity is great helpful to the airspace planning.This article based on the different of aircraft performance,propose the aircraft trajectory characteristic parameters,combined with the way of conflict relief to evaluation of en-route capacity.The specific work is as follow:1.Analysis the factors of the influence to the aircraft trajectory characteristic,and the relationship between the en-route capacity and these factors.Summarizes several internationally aircraft classification methods.Base on the speed?voyage?ceiling of the aircraft in our country,propose an aircraft classification method in our country.2.Combine with the ADS-B data of Tianjin peripheral airspace and the data provided by airlines,use entropy method analysis the speed?clime rate?decline rate of aircraft.Get the speed?clime rate?decline rate of different aircraft in every flight level.Analysis the relationship between speed?clime rate?decline rate and en-route capacity.3.Take the way by change the speed or change the flight level of the aircraft when conflict happen.Analysis the loss of the capacity by every way to resolve the conflicts.Given the model of the en-route capacity for different types of en-route.Test and verify by simulation.Proposed a close to reality and effective way to evaluate en-route capacity.
