Research On Area Control Conflict Resolution Of Chengdu New Airport In Trajectory Based Operation

In order to cope with the rapidly increasing flight flow and the more complex route structure after Chengdu Tianfu Airport was put into operation,this theory introduces the technology of track-based operation(TBO)to study the issue of airspace control deployment in Chengdu area.The core of using track-based operation technology(TBO)is to explore the operational difficulties and solutions in the airspace of the new airport under the condition of conflict relief operation based on the control and deployment method under the accurate trajectory prediction and conflict detection.This paper firstly studies the changes of air route structure and historical peak flow in Chengdu after Tianfu Airport is put into operation,and predicts and models the future airspace operating environment.The time is discretized by the horizontal correlation of the aircraft,and the vertical track adjustment model is established and experiments are carried out to explore its limitations.Then,the horizontal track adjustment model is established by the A*algorithm based on the principle of first-come-first-served,last-come first adjustment,and its limitations are also discussed through experiments.According to the experimental results of the conflict relief model between the horizontal track and the vertical track,the concept of stacking is proposed to combine the horizontal and vertical adjustment strategies to establish a hybrid release strategy model,and its effectiveness is verified by experiments.Based on the mixed conflict resolution strategy model,a simulation experiment was carried out on the airspace after Tianfu Airport was put into operation.According to the experimental data,five main conflict zones in the area under the track-based operation mode were found,and flight conflicts and deployment measures were analyzed.According to the five major conflict zones,optimization suggestions such as adjusting entry and exit points and changing routes within the region are put forward,and the optimization measures are verified by the Sichuan University Zhisheng simulator,which proves the control load,airspace operation efficiency,and aircraft comfort in the optimized operation mode.,four aspects of aircraft safety have been improved.
