not that french one that happend 6 months or so ago. i dont even think they lost engine power... all it was- the speed sensors froze up, telling the computers there was no airspeed. that shut down the whole system, the pilots panicked and didnt know how to keep altitude (which they say is trivial for any pilot- something about nosing up 5deg tilt and 50% engine power or something, i cant remember exactly). no survivors due to pilot error basically. granted, they had ZERO instruments, they were in a severe storm and every alarm they had was screaming at them.
No, nothing at all "shut down" on the plane. The auto pilot system disengaged due to lack of airspeed data. The plane was working normally otherwise. All sensors and indicators functioned normally except for the airspeed indicator for a short while.
They were without accurate airspeed data for less than one minute. Had they sat on their hands for 60 seconds, they would have been fine.
The plane's own momentum carried it through the area of icing and the pitot tubes were clear in about 50 seconds.
Had they pushed the auto pilot button after one minute, they'd still be here.
The only thing that shut down was the pilot flying the plane. For some reason we will never know, he pulled up when the autopilot disengaged, then he kept the the nose of the plane pointed up, and no one else seemed to notice.
