德翼失事客机未发出“求救信号”

德国之翼航空公司一架客机于当地时间3月24日在法国南部坠毁，机上150名乘客和机组人员全部遇难。民航部门的消息说，失事客机没有发出求救信号，是空管人员在与客机失去联系后，宣布客机失踪的。

French investigators will sift through wreckage on Wednesday for clues into why a German Airbus ploughed into an Alpine mountainside, killing all 150 people on board including 16 schoolchildren returning from an exchange trip to Spain.

法国调查人员将仔细筛查失事飞机残骸寻找失事原因线索。这架德国空客客机撞上阿尔卑斯山区一侧，导致机上150人全部丧生，其中包括16名从西班牙交换生项目返回的学生。

France's DGAC aviation authority said air traffic controllers initiated distress procedures after they lost contact with the Airbus, which did not issue a distress call.

法国民航总局表示，失事客机并未发出求救信号，是空管人员在与客机失去联系后启动了遇难求救程序。

Distress call就是“求救信号、呼救信号”，指国际上通行的飞机或轮船遇险求救信号，有时也用mayday call表示，因为mayday是国际通用的无线电通话遇难求救讯号，Mayday是法语“Venez m'aider.”（快来帮帮我）之中“m'aider”的谐音。在无线电内发出Mayday呼唤，是指遇上了威胁生命的即时危险情况。
