| With the continuous development of the civil aviation industry,the number of airports in the same terminal area is also increasing resulting in an increase in air traffic in the terminal area.The number of arrival and departure air routes are also increasing,which increases the airspace complexity and the work pressure of the control staffs.In order to ensure the safe operation of aircrafts in the terminal area in such a high-density traffic flow and to reduce the workload of the control staffs,it is necessary to constantly improve the flight procedures and deploy the conflict between the arrival and departure routes.This paper realizes the automatic deployment of collisions between arrival and departure routes in multiple airports based on the "Automatic Conflict Recognition System for PBN Instrument Flight Procedures in Large Terminal Area" of North Air Traffic Management Bureau.In this paper,the processing of multi-airport arrival and departure data is introduced including the analysis of DXF files,normalized drawing of departure and arrival routes,additional route supplemental data,and normalization of multiple airport coordinate origins.They are the data basis for the deployment of routes conflicts.A deduction of height was later achieved according to initial gradient values and related data with foundation of analysis of the routes intersections.Based on the relevant rules of operation and air traffic management regulations,this paper summarizes the algorithms for conflicts identification,deployment and validates them with relevant data.This algorithm realizes the routes conflicts automatic deployment based on the analysis of arrival and departure gradient to deal with the routes conflicts.This paper realizes the arrival and departure route display in Baidu map through using VC++ programming technology,which realizes the visualization of the system making the identification and deployment results between routes more intuitive and convenient to display. |
