随着空中交通流量的大幅增加,航班延误现象不断发生。终端区容量评估的有效性是制定航班计划的重要依据。文章在对终端区进行容量评估时考虑了延误水平,以华北终端区为例,运用回归分析方法量化了延误时间与航空器数量之间的关系,为空管当局找到延误和容量之间的平衡点提供了良好的方法,同时得到更准确的终端区容量值。 With the substantial increase in air traffic, flight delays continue to occur. The validity of terminal area capacity assessment is an important basis for formulating flight plans. The article takes into account the delay level in the capacity assessment of the terminal area. Taking the terminal area of ​​North China as an example, the paper uses the regression analysis method to quantify the relationship between the delay time and the number of aircraft. It is the balance between delay and capacity found by the ATC administration Provides a good way to get a more accurate terminal area capacity value at the same time.
