基于RECAT-CN的新郑国际机场跑道容量影响研究

Research on Runway Capacity of Xinzheng International Airport Based on RECAT-CN

航空器尾流间隔是影响机场跑道容量的重要因素之一,其标准如果过于保守,将直接影响跑道容量的提升和机场的运行效率。为研究我国尾流再分类标准(RECAT-CN)对机场跑道容量提升的影响,文章首先介绍了现行雷达尾流间隔标准和RECAT-CN标准,并以郑州新郑国际机场某一天进场机型为具体研究对象,建立平均尾流间隔模型。对比现行CCAR-93-R5标准和RECAT-CN标准,定量论证RECAT-CN标准对机场跑道容量的提升作用,求出机场尾流间隔缩减率,为机场运行决策和效率提升提供理论参考。

Wake turbulence separation is a major factor for determining runaway capacity.Over-conservative separations will directly slow down the exansion of the runway capacity and the efficiency of the airport operation.In order to study the influence of RECAT-CN on the expansion of runway capacity,this paper first introduces the current radar wake interval standard and RECAT-CN standard,and establishes the average wake interval model by taking the aircraft entering Zhengzhou Xinzheng International Airport one day as the specific research object.Compared with the current CCAR-93-R5 standard and RECAT-CN standard,the effects of RECAT-CN standard on the expansion of runway capacity are quantitatively demonstrated,and the reduction rate of wake turbulence separation is calculated,which provides theoretical reference for airport operation decrsion-making and effecieney improvement.
