从达拉斯/沃斯堡国际机场（DFW）起飞的飞机遇到垂直限制，阻止连续上升操作。这些限制的结果是在10,000英尺的高度暂时保持水平。已经发现，流动方向、特定区域导航（RNAV）航线几何形状和到达流的组合是临时平层的持续时间和频率的最大因素。总的来说，20%的DFW起飞受到这些平飞的影响，平均持续时间超过100秒。DFW采用连续下降进近可以减少到达对离场的影响，并允许更多的连续上升。连续上升和暂时平飞的上升所用的燃油是使用燃油燃烧率模型计算的，该模型是根据实际飞机航迹数据、飞机制造商飞行操作手册和Eurocontrol的飞机数据库（BADA）模拟工具创建的。该模型代表DFW当前机队组合的平均总燃烧率。连续上升将节省大约7加仑的燃料，而每次起飞时，450加仑的燃料将用于爬升到31,000英尺的巡航高度。
Aircraft departing from the Dallas/Fort Worth International Airport (DFW) encounter vertical restrictions that prevent continuous ascent operations. The result of these restrictions are temporary level-offs at 10,000 feet. A combination of flow direction, specific Area Navigation (RNAV) route geometry, and arrival streams have been found to be the biggest factors in the duration and frequency of a temporary level-offs. In total, 20% of DFW departures are affected by these level-offs, which have an average duration of just over 100 seconds. The use of continuous descent approaches at DFW are shown to lessen the impact arrivals have on the departures and allow more continuous ascents. The fuel used in a continuous ascent and an ascent with a temporary level-off have been calculated using a fuel burn rate model created from a combination of actual aircraft track data, aircraft manufacturer flight operations manuals, and Eurocontrol's Base of Aircraft Data (BADA) simulation tool. This model represents the average aggregate burn rates for the current fleet mix at DFW. Continuous ascents would save approximately seven gallons of fuel out of 450 gallons used to climb to a cruise altitude of 31,000ft per departure.
