PLANE 2 LAST

DFDAU is similar to the 'black box' Digital Flight Data
Recorder(DFDR) but stores information only for a shorter
period of time.
CVR captures radio transmissions and sounds in the
cockpit such as the pilot's conversation with the Air Traffic
Controller and engine noises.
Analysis of CVR and DFDAU is expected to take at least a
fortnight while the analysis of all records and documents
collected would also take same time.
A preliminary replay and analysis of the audio taped
conversation between the Air Traffic Control at the Bajpe
Airport and the pilots of the Boeing 737-800, moments
before the crash was carried out Monday, official sources
said.
Four teams of investigators from engineering, operations,
ATC and aerodrome units made several rounds of inspection of
the wreckage, the runway and the adjoining areas of the
accident site in the hunt for the "Black Box' which will
provide authentic information as to what went wrong at the
last moment before the flight was set to land.
These teams have also collected a large number of
material for evidence through extensive search of the
aerodrome, runway and navigational facilities, the sources
said.
An official statement had Monday said that though the
CVR was "affected by fire, it is expected to yield the desired
information".
The teams have already taken over all records pertaining
to the aircraft and the air crew for investigations, the
sources added. PTI
