We’ve seen already that the large majority of airport pairs are flown by business aviation less than once a week (Figure 11). This follows natu-rally from the service-on-demand principle which typifies business avi-ation. However, this high level of service does not lead to a uniformly thin and light loading on the total air traffic network. One of the factors that helps to manage the flow of air traffic is its reg-ularity. Scheduled services and to a lesser extent (tourist) charter traf-fic are regular, following a rather uniform, predictable pattern. This regularity of the bulk of flights is a great assistance, whether for resource planning a few months in advance as part of network plan-ning, pre-tactical planning on the day before, tactical flow manage-ment on the day, or air traffic control once airborne. A particular interest for EUROCONTROL is flow and capacity manage-ment, which the Agency is responsible for coordinating across Europe, through its Central Flow Management Unit (CFMU). Flow manage-ment aims, in real time, to match demand to the available capacity: it is safer, more cost-effective and better for the environment if an air-craft waits on the ground before departing rather than be held en route or prior to arrival in the air, or to overload particular sectors of air-space. Figure 18 illustrates the peaks in business aviation demand. The dia-gram focuses on airports of the size typically used by business aviation, with up to 100 business or scheduled departures per day. The figure contrasts the average daily traffic in the period with the busiest day. For scheduled traffic there is some variation – a 20% difference between weekday and weekend day is not unusual, for example – and in most cases with the scheduled traffic there is little more than this. Where there are bigger differences, perhaps because of tourist change-over days, these are scheduled well in advance and are manageable. 24 Figure 18. Business aviation generates more, bigger peaks at quieter airports: the maximum daily departures are often several times as big as the average. (Illustrated are airports with up to 100 business or scheduled departures/day in 2005.) 中国公务机网 www.gongwuji.com 公务机翻译 www.aviation.cn 本文链接地址：Getting to the Point Business Aviation in Europe(20) |
