Evaluation of Coordination between Performance-Based Navigation (PBN) Flight Procedure Design and Aerodrome Operating Conditions Based on Interval Number

The coordination between PBN flight procedure design and aerodrome operating conditions (CBPFPDAOC) is related to the utilization of the aerodrome airspace, the medium and long-term flight procedures planning of aerodrome, the quality and the efficiency of air traffic management and even the safety of aircraft. In practice, the judgment about the CBPFPDAOC is usually made by the experts, based on their specialized domain knowledge and experience. This human-made judgment could be bias and arbitrary. To address this problem, we did research by applying the knowledge of interval evaluation. According to the features of PBN flight procedures and on the basis of the comprehensive consideration of the many factors on aerodrome operating conditions, we established a comprehensive evaluation index system about the CBPFPDAOC; and then based on the principle of interval evaluation, we constructed the comprehensive assessment model on the CBPFPDAOC which based on the determination of the evaluation level. We give details of this method in this paper, including constructing evaluation indicator system, obtaining values of each indicator, building comprehensive evaluation of mathematical model, and finding solution of the model, etc. At the last part of this paper, we present a numerical example to demonstrate this method is practical, reasonable, and feasible.
