近距平行跑道是指跑道中心线间距小于760米的平行跑道。在国外繁忙机场,这种跑道布局方式是缓解起飞和落地交通流冲突,提升机场保障能力的重要手段之一。其优点不言而喻,可以在有限的土地资源条件下,为起飞和落地航空器分别单独分配使用跑道,从物理形态上,杜绝起飞和落地航空器的碰撞风险。随着2008年3月,上海浦东国际机场启用第三条跑道,也就是国内第一组近距平行跑道正式启用,国内大型机场近距跑道的建设也有增速的趋势。2010年3月,上海虹桥国际机场也正式启用了第二条跑道,与原跑道形成一组间
Close parallel runway is the runway center line spacing of less than 760 meters parallel runway. At busy foreign airports, this kind of runway layout is one of the important means to mitigate the conflict of take-off and landing traffic flow and enhance the airport’s security capability. Its advantages are self-evident. It is possible to allocate separate runways for takeoff and landing aircraft under limited land resources and to physically avoid the risk of collision of take-off and landing aircraft. With the opening of the third runway in Shanghai Pudong International Airport in March 2008, that is, the opening of the first group of close parallel runways in China, the growth of the near-runway at large domestic airports also increases. March 2010, Shanghai Hongqiao International Airport also officially opened a second runway, formed with the original runway between
