摘要
尾流间隔是跑道容量的主要影响因素,近年来FAA试行并逐步推广的尾流标准重新分类(RECAT)对跑道运行效率提升具有积极作用。在分析比较现行和RECAT尾流间隔标准的基础上,面向我国运行实际建立了机场跑道容量模型,建模中考虑了距着陆接地点至少4 000 m发布落地许可的具体规章要求,针对实例分析了RECAT下不同机型比例对跑道容量的影响程度,对于空管运行和跑道利用效率提高具有实际应用价值。
Wake turbulence separation is a major factor for determining runaway capacity. REACT, drawn up and carried out by FAA recently, is playing a positive role in increasing runaway capacity. This paper, by establishing runaway arrival capacity model in which 4 000 m landing clearance requirement in domes- tic ATC Rules is took into account, makes a comparison of wake turbulence separation standard between the existing minima and RECAT, and analyses the impact of the different proportion of aircraft types on arrival capacity. Numerical example shows that RECAT can greatly increase runaway capacity and possess practical application.
