RECAT尾流间隔对配对进近跑道容量影响

Effect of RECAT Wake Interval on Runway Capacity under Paired Approach

空中交通流量的增加导致机场跑道容量饱和,为提高跑道容量和机场运行效率,在尾流间隔重新分类标准下对跑道容量进行评估。选用近距平行跑道配对进近运行模式,建立机场跑道进场容量模型,对比我国现行尾流间隔标准与RECAT尾流间隔标准对机场跑道容量的影响程度。以重庆江北机场为实例,验证结果表明使用RECAT尾流间隔标准能提高10.6%/时的航班架次。对其他类似机场跑道容量评估提供理论支持,具有一定的实际应用价值。

The increase of air traffic flow leads to the saturation of airport runway capacity.In order to improve the runway capacity and airport operation efficiency,the runway capacity is evaluated under the criterion of reclassification of wake interval.An airport runway approach capacity model is established by using a closely spaced parallel runway on paired approach mode,and the impact of China's current wake interval standard and RECAT wake interval standard on runway capacity is compared.Taking Chongqing Jiangbei Airport as an example,the results show that the flight number can be increased by 10.6%per hour by using RECAT.It can provide theoretical support for other similar airport runway capacity evaluation and has certain practical application value.
