India's aviation watchdog is investigating why a Jet Airways¹ Ltd (JET.NS) flight plunged² almost 5,000 ft (1,520 m) over Turkish airspace last week, after some news reports said one pilot was asleep and the other was busy on a flight management device.[/en]

上周，捷特航空（印度第二大航空公司）的一架飞机在土耳其领空突降5000英尺（1520米），一些新闻报道称当时一名机师睡着了，而另一名机师则在忙着查看飞行管理设备。印度航空监管机构正在对事故原因进行调查。

The aircraft, operated by India's second largest airline, dropped suddenly during a flight between Mumbai and Brussels last Friday.

上周五，这架捷特航空飞机在从孟买飞往布鲁塞尔的途中突然下降。

According to The Times of India newspaper, the co-pilot was supposed to ensure the aircraft remained steady while the commander took a permitted rest.

据《印度时报》报道，机长按规定可以进行小憩，在他休息期间，副机师应确保飞机的平稳飞行。

The co-pilot has since told the aviation regulator she was using her electronic flight bag - a portable display system used to speedily execute flight management tasks - and did not realise the aircraft had lost altitude, the newspaper reported, quoting an unnamed source.

报道中，一名未透露姓名的知情人士提及，副机师事后向航空监管部门解释，她当时正在使用电子飞行包，没有注意到飞机突然下降。电子飞行包是一种用于处理飞行管理任务的便携式显示系统。

Both pilots "have been taken off the roster³ pending⁴ inquiry⁵" and were summoned for questioning on Wednesday, the Directorate General of Civil Aviation said in a statement.

印度民用航空总局在周三的声明中表示，两名机师“已被停飞”，正被传讯调查。

The investigation⁶ into the incident will consider whether the pilots were trained adequately and whether fines should be levied⁷ on them, the aviation body said.

航空总局还表示，其将调查两名机师是否受过充分培训，并根据事故调查结果决定是否对两人进行罚款。
