ZitatAlles anzeigenThe French BEA reported the loss of all three airspeed indications, the German BFU is investigating the serious incident.
On Jan 30th 2013 the investigator leading this investigation at the German BFU told The Aviation Herald, that the crew believed all three air speed indications were invalid due to their observations, there were no flags or ECAM indications. The BFU was notified about the loss of all three airspeed indications, downloaded the flight data recorder and found that the indicated airspeeds properly correlated with the actual ground speed. A mismatch between active automation modes and pilot expectation is currently considered as a working theory.
The aircraft performing flight EY-1 from Abu Dhabi (United Arab Emirates) to Frankfurt had previously diverted to Munich due to weather.
