摘要(Abstract):
为了探究空中交通管制运行间隔在空间上的直观表现,深入研究管制运行间隔在航空器进场运行方面的内在规律,为空中交通管制工作提供贴切可靠且有前瞻性的指导,利用深圳机场进场航空器的ADS-B数据得到了深圳机场进场航空器运行间隔的统计分布,并考虑问卷调研结果,划分进场流量时段。继而通过进一步分析发现航空器的运行间隔、飞行高度及距接地点的水平飞行里程3种参数之间具有显著的相关关系,其中航空器距离接地点的水平飞行里程是影响航空器运行间隔分布更重要的因素,提出并证明了在航空器进场水平位置上“等间隔带”的存在。最后,通过Kriging法对尚未被航迹覆盖到的位置点所需间隔进行合理预测,计算得到了完整反映终端区交通态势的航空器运行“等间隔带”,并经过分析明确了影响“等间隔带”分布的关键因素。提出了“等间隔带”的理念,该理念及其相关分析可为空中交通管制工作和管制智能化发展等方向的研究提供基础和参考。
