香港航班信息被曝“失踪”75秒 航班暂停4分钟

2016-12-14 04:02:19   

京华时报讯据香港《文汇报》报道,香港民航处新航空交通管理系统继上月29日后,再次发生航班资料消失事件。

民航处发言人透露,事发于12日中午约12时,系统的雷达显示屏幕未能显示航班呼号及飞机航速等数据,但仍有显示飞机目标的位置和飞行高度。数据约75秒后自动重新显示。

发言人称,因民航处于12月8日起已可透过ADS-B,看到飞机位置的数据,故空管人员于12日事发时,可在同一工作席位上雷达显示屏旁的另一个屏幕,看到那些短暂未能显示的信息,故事件并没有影响航空安全。不过为审慎起见,空管人员期间曾暂停处理离境航班4分钟。

香港民航处新空管系统屡出状况,据公开报道,自11月全面启用以来,已出现至少3次航班信息“失踪”事件。

发言人表示,雷神公司的高层人员经调查和分析后,事件成因主要是由于有工作人员进行系统保养工作时,从主系统抽取数据并存盘,在过程中,系统先处理抽取数据并存盘,预计在短时间内再处理航班数据,导致航班数据短暂未能够及时与雷达数据配对。

民航处发言人称,已就今次事件,再次提醒工作人员有关安排,以避免再出现类似情况。事件中航班数据没有流失或损坏,新空管系统的其他功能亦如常运作。另外,雷神公司已提交系统优化程序。
