Search Commences for Flight Data Recorder of Crashed AI Express Plane
Teams of the Directorate General of Civil Aviation (DGCA) and police have begun their search for the digital flight data recorder, a part of the black box, at Air India Express plane crash site at Mangalore, said media reports.
On late Sunday, the cockpit voice recorder (CVR) and a part of the black box having the digital flight data acquisition unit (DFDAU) were recovered.
Black box is a word used for two pieces of equipment – the digital cockpit voice recorder and the flight data recorder, which provide significant inputs to investigators on cause of air accidents.
One device of the equipment records all conversations inside the cockpit and those with the air traffic controllers, while the other has the history of the aircraft’s flight details, such as acceleration, engine thrust, airspeed, altitude, rudder position, which are also vital for crash investigations.
According to a DGCA statement, fire has affected the cockpit voice recorder of the crashed plane but it is expected to produce the desired information, reports said.
The statement said that the DFDAU, a parallel unit of the digital flight data recorder recording flight parameter for shorter duration, was recovered but search continues for flight data recorder, said reports.
“Analysis of CVR and flight data will be conducted in the next fortnight. Similarly, analysis of records pertaining to the crash will take a couple of weeks,” a probe official was quoted a saying.
