Quality Assessment of Air Traffic Control System Proximity Control Service Process Based on Principal Component Analysis and Grey Comprehensive Analysis

Abstract

Abstract Aiming at the operational process of air traffic control service, aiming at improving safety and efficiency, this paper analyses the main factors affecting the process of air traffic control service, chooses corresponding indicators, eliminates the indicators with correlation and information overlap by using principal component analysis, determines the key indicators system, and then uses grey comprehensive analysis method to analyze the quality indicators system of air traffic control service process. Through the evaluation, the number of conflict risks of the aircraft in the sector, the sorties flown simultaneously with the aircraft in the same area, the sorties flown simultaneously with the aircraft on the landing route, and the total time occupied by the aircraft on the runway have the most significant impact on the air traffic approach control. This is the case. Finally, the feasibility of this method is verified by an example analysis.
