5月中国航班正常率为72.46% 326个航班受无人机影响

2017-06-13 20:32:35   国际在线

国际在线报道(记者李琳):中国民用航空局13日举行例行发布会。会上发布的数据显示,5月份中国航班正常率为72.46%,同比下降6.3个百分点,造成延误的主要原因是天气和空域活动。此外,针对近日备受关注东航客机返航事件,民航局相关负责人称,如果调查显示确实是发动机存在设计和制造问题,将发布适航指令。

今年以来,中国民航安全形势总体平稳向好。数据显示,5月份,民航实现运输飞行86.7万小时,同比增长13.9%。截止5月31日,中国民航实现运输航空安全飞行81个月、5052万小时,持续保持着中国民航历史上最好的安全纪录,也好于世界民航平均水平。

不过,民航局运行监控中心党委书记张春枝介绍,5月份全国航班正常率为72.46%,同比下降6.3个百分点。据她分析,造成5月份航班正常率下降的主要原因是天气和空域活动,占延误航班的80.34%:“天气原因占延误航班的50.68%,主要是雷雨天气对长三角和珠三角地区影响较大,造成浦东、虹桥、杭州、广州、深圳等机场大量航班出港延误,部分航班返航备降。空域活动占延误航班的29.66%,主要是华东、新疆地区的机场受影响较为严重。”

此外,无人机的违规飞行也在影响航班的正常运行。5月份西南、西北、中南地区机场共有19次无人机影响航班正常运行事件,使得326个航班受到影响,其中101班返航备降,给安全运行和旅客出行带来了不便。当前,民航局正在加大无人机管理力度。从今年6月1日开始,民航局要求在中国运行的民用无人机进行实名制登记。截至6月12日,在民航局无人机实名登记系统上注册登记的民用无人机已达到4.5万架。

每年的六至八月往往是中国的雷雨台风多发季节,也是大面积航班延误和突发事件的多发时期,给民航的平稳运行带来很大的挑战。张春枝表示,民航局将采取系列措施应对雷雨季节的到来:“根据气象部门恶劣天气的预测,依据大面积航班延误预警的程度,督促航空公司、机场、空管等运行单位加强会商,尽早采取调整制度航班计划、改变飞行航线等措施,降低对航班运行和旅客出行的影响。当机场即将或已经发生大面积航班延误的情况时,及时启动响应程序,组织运行单位加强协同配合,共同处置。”

6月11日,中国东方航空公司一架从悉尼飞往上海的航班由于发动机故障造成返航事件引发了社会关注。民航局航空安全办公室主任唐伟斌表示,目前事故正在调查中:“目前,该起事件由澳大利亚运输安全局(ATSB),依据国际民航公约附件13《航空器事故和事故征候调查》相关规定组织调查。当然,中国民航我们也会参与调查工作,包括制造商。这架飞机的发动机型号是英国罗罗公司生产的遄达700。根据我们的了解,发生类似的故障不是第一次,目前ATSB已经介入调查,同时与我们取得了联系。相关事件的信息和调查结果的发布,由ATSB负责。”

民航局航空器适航审定司副司长王京玲表示,如果调查结果发现确实是属于发动机设计、制造问题,中国民航局将考虑发适航指令。
