目前为民航运输机装备低能见度着陆设备的工作可能会限制机场的容量,这是因为现行防止跑道入侵的表面交通管制步骤会减少低能见度下的机场容量。为去除这个瓶颈,正在发展一些新技术,而星基全球定位系统(GPS)将在其中起重要作用。民航公司机队中具有Ⅲ类着陆能力的现代飞机数量的增加已对机场表面的交通产生影响。去年年初,英国史密斯系统工程咨询公司发表了一篇报告,指出在伦敦希思罗和盖特威克机场,“即使交通量不增加,预计1995年以前地面运动管制也会限制低能见 The current deployment of low visibility landing gear to civil air transport aircraft may limit the capacity of the airport because the current surface traffic control steps to prevent runway incursions will reduce airport capacity at low visibility. To remove this bottleneck, some new technologies are being developed, and satellite-based global positioning system (GPS) will play an important role. The increase in the number of modern aircraft of Civil Aviation Corporation fleet with Class III landing capability has had an impact on the traffic on the surface of the airport. Earlier last year, Smith & Systeme Consulting, a British firm, published a report stating that at Heathrow and Gatwick airports in London, "Even without increased traffic volume, surface movement regulation is expected to limit low-visibility by 1995
