摘要

Many airports in Europe and the US are operating close to their maximum capacity and the growth of air traffic causes increasing delays, especially during peak hours. In Europe aircraft usually operate under Instrument Flight Rules (IFR). For approach and landing minimum aircraft wake vortex separations depend on aircraft weight category (small, large, heavy), largely in agreement with ICAO recommendations. For departures, usually time based separations apply. The current wake vortex separation rules are generally believed to be sufficiently safe, but rather conservative in certain weather conditions. The present report addresses the possibility of applying head- and/or crosswind depending reduced aircraft separations during the landing and departure phase. Taking the mean annual wind conditions for aircraft operations at Schiphol Airport as an example, an initial estimate is made of the potential landing and departure capacity benefits for different wind-dependent aircraft separation strategies. For steep approach procedures (as being considered for reduced noise emissions) the initial assessments indicate a large potential gain in airport capacity. However, further study will be needed to assess the practical limitations and safety aspects for the proposed modified aircraft separation strategies.
