Abstract

Abstract: In order to solve the problem of stricter restrictions on clearance conditions of the plateau airport, a safety evaluation model is constructed by using the statistical modeling method to improve the obstacle compensation correction. Firstly, based on the rectangular model and CRM, the influence of the height compensation correction amount on the obstacle collision risk probability was studied. Then, the safety area lower limits of plain and plateau airports were calculated according to the model and the correspondence between the average lower limit and the airport elevation was analyzed to obtain the improved obstacle height compensation correction amount. Finally, the correction was applied at Kunming Airport to verify its safety and practicability. The results show that the altitude compensation correction at the plateau airport exerts a significant impact on the probability of collision risk; the height compensation correction per kilometer for Class C aircraft can be improved from 2.88 m to 2 m, and the improved height compensation correction can bring a greater operational advantage.

Key words: plateau airport, airport clearance, track deviation, height compensation correction, collision risk model(CRM)
