航空器进场效率量化评价及其影响因素分析

终端区已成为制约民航发展的瓶颈区域,且中国在终端区进场效率评价方面仍停留在定性分析阶段,缺乏量化的指标。选取以机场跑道中心点为圆心,100海里为半径的圆形区域作为研究区域,结合ADS-B数据对航空器进场效率进行研究分析。以天津滨海国际机场为研究对象,筛选进场航空器的ADS-B数据,利用K-means聚类对不同进场方向的航空器加以区分,分别计算各方向进场效率,并进一步分析影响进场效率的因素。发现进场航线、进场航空器队列长度和机型对航空器进场效率有明显影响,而起飞航班数量对进场效率的影响不显著。

Quantitative Evaluation of Aircraft Entry Efficiency and Its Influencing Factors

Terminal area has become a bottleneck restricting the development of civil aviation, and China in the terminal area approach efficiency evaluation still remain in the qualitative analysis stage and lack of quantitative indicators.A circular area with a radius of 100 nautical miles was selected as the study area, and the efficiency of the aircraft was investigated by ADS-B data. The ADS-B data of the approach aircraft were screened by Tianjin Binhai International Airport. The K-means clustering was used to distinguish the aircraft in different approach directions. The efficiency of each direction was calculated and the influence of the entry efficiency was analyzed. It is found that the approach route, the length of the aircraft queue and aircraft type have a significant effect on the efficiency of the aircraft entry, and the impact of the number of takeoff flights on the efficiency of the entry is not significant.
