The Cockpit Voice Recorder (CVR) of the Pakistan International Airlines (PIA) flight PK-8303 is still missing after it crashed on Friday in Karachi’s Model Colony area killing 97 out of 99 people on board.
According to PIA spokesman – Abdullah Hafeez Khan, the CVR of the crashed plane which is located at the rear end of the plane, is still missing and has not been recovered from the crash site so far. He cited that the CVR might have been dislocated as the plane’s tail was the first to hit the ground, the same place where CVR is installed.
“Voice recorder is important for the plane crash inquiry,” he noted.
Authorities have extended the search area and round the clock efforts are being made to recover the plane’s CVR so that its data can be analysed which is essential in crash investigation and will significantly assist the investigators in finding out the cause of the crash, he added.
What is a plane’s CVR?
Cockpit voice recorder (CVR) is a flight recorder used to record the audio environment in the flight deck of an aircraft via recording the signals of the microphones and earphones of the pilots’ headsets and of an area microphone in the roof of the cockpit for the purpose of investigation of accidents and incidents.
The latest CVRs employ solid-state memory and use digital recording techniques, making them much more resistant to shock, vibration and moisture. It is mounted in the rear of the airplane fuselage to maximize the likelihood of its survival in a crash.
