破雾系统首次上阵 5架飞机浓雾中盲降武汉机场

破雾系统首次上阵

原标题:“破雾系统”首上阵 5架飞机迷雾中“盲降”武汉

武汉晚报讯(记者张全录 通讯员欧阳涛)昨天一早,大雾笼罩天河机场,能见度一度降到250米。以往,能见度低于550米时,飞机只能备降其他机场。但昨天有5架飞机首次在能见度300米条件下,成功突破迷雾“盲降”天河机场。

昨天凌晨5时开始,天河机场逐渐被浓雾包裹。7时整,跑道能见度一度降至300米,塔台宣布启动低能见度运行程序。

7时50分,从泰国曼谷机场回武汉的南方航空3030航班破雾而出,稳稳降落在东跑道。

这是天河机场在最大航空能见度低于550米的情况下降落的第一架飞机。

8时50分,机场浓雾渐渐消散,本次低能见度运行程序结束。

记者了解到,在1个多小时的低能见度(300米—550米)运行程序期间,共有5架航班安全降落。

粗略估算,这5架飞机的“破雾”降落,为航空公司节约了数十万元的运行成本,也提高了机场的运行效率。

民航湖北空管分局相关工作人员介绍,今年他们在天河机场安装了场面监视系统,即16双分布在机场跑道、滑行道、联络道等处可穿越迷雾的“眼睛”。

该系统与已有的场面监视雷达信息在场监自动化中完成数据融合,可以解析飞机发出的监视系统数据,获得每架飞机全球唯一的24位地址码,计算出飞机的准确位置,定位误差仅2米左右。

这些穿越迷雾的“眼睛”与分布于机场跑道上的仪表着陆系统相互配合,构成了盲降系统。

经过一系列软硬件的提升,今年2月1日武汉天河机场特殊二类和标准二类低能见度运行程序被民航总局公布生效。昨天,该程序第一次有了用武之地。
