Pilots of the crashed Air France flight lost vital speed data, France's investigators said on Friday based on the reading of the plane's salvaged flight data recorder, or black box, CNN reported.

The air speed displayed on the left primary flight display was "inconsistent" with those on the integrated standby instrument system (ISIS), which may have caused the crash, according to interim reports.

Miles O'Brien, a pilot and aviation analyst suggested the flight's pilot might have got wrong information that the air speed was too high, so he pulled up the nose to reduce it, leading the aircraft to stall and eventually crash. （点击美国有线电视新闻网查看原文）

法航失事客机原因查明

       据美国有线电视新闻网报道，法国调查人员在解读失事客机“黑匣子”记录的数据后，于当地时间周五公布了法航空难的初步调查结果，称失事客机的飞行员当时未掌握关键速度数据。

       初步调查报告指出，失事飞机上左主屏的显示空速数据与集成后备系统(ISIS)上的真实数据“不一致”，可能导致了飞机坠毁。

       飞行员、航空研究专家迈尔斯•奥布赖恩猜测失事飞机上的飞行员可能得到了错误的信息，以为飞机速度过快，飞行员于是就拉起机头尝试减速，从而引发飞机失速，并最终坠毁。
