新的大型飞机(NLA)，最初是空中客车A380，在现有的旧机场引入带来了广泛的尺寸净空问题，主要与翼展和机尾高度有关。许多现有机场无法满足美国联邦航空局的飞机设计第六组(ADG VI)适用于NLA的设计标准。美国联邦航空局正在对波音-747飞机在各种天气和能见度条件下与滑行道中心线的测量偏差进行持续的数据收集，以允许估计滑行时的碰撞风险。根据联邦航空局2000年9月至2002年4月在阿拉斯加安克雷奇国际机场和1999年6月至2000年2月在纽约肯尼迪机场收集的数据，初步分析了飞机在普通滑行情况下发生碰撞的风险。在锚地调查了29,544个偏差，在肯尼迪机场调查了20,702个偏差。进行分析以评估大偏差的概率。这些概率最终被用来评估NLA翼尖与固定或可移动物体接触的风险，以及同时滑行的两架飞机发生碰撞的联合概率。两架正在滑行的A380飞机发生翼尖相撞的概率计算为：ADG Code V滑行道为1.74×10-2，JFK滑行道间隔300英尺为4.91×10-15，ADG Code VI滑行道为4.42×10-23。滑行中的B-747-400与A380相撞的概率分别为：ADG Code V滑行道1.5×10-11，JFK滑行道间隔300英尺4.91×10-15，ADG Code VI滑行道2.12×10-23。
The introduction of new large airplanes (NLAs), initially the Airbus A380, into existing older airports poses a wide range of dimensional clearance issues, primarily related to wingspan and tail height. Many existing airports cannot meet FAA’s Airplane Design Group VI (ADG VI) design standards appropriate to NLA. FAA is conducting ongoing data collection of measured deviations from taxiway centerlines experienced by Boeing-747 airplanes under various weather and visibility conditions, to allow the estimation of the collision risk while taxiing. A preliminary analysis was conducted on the risk of collisions involving airplanes in common taxiing situations, based on FAA data collected at Anchorage International Airport in Alaska from September 2000 to April 2002, and at New York’s John F. Kennedy Airport (JFK) from June 1999 to February 2000. Investigated were 29,544 deviations at Anchorage and 20,702 deviations at JFK. Analyses were performed to assess probabilities of large deviations. The probabilities were finally used to assess the risk of NLA wingtip contact with fixed or movable objects and the joint probability of collision between two airplanes that are taxiing simultaneously. The probability of wingtip collision between two taxiing A380 airplanes is calculated as 1.74 × 10-2 for ADG Code V taxiways, 4.91 × 10-15 for a JFK taxiway separation of 300 ft, and 4.42 × 10-23 for ADG Code VI taxi-ways. The probability of collision between a taxiing B-747-400 and an A380 is 1.5 × 10-11 for ADG Code V taxiways, 4.91 × 10-15 for a JFK taxiway separation of 300 ft, and 2.12 × 10-23 for ADG Code VI taxiways.
