general of civil aviation has ordered an inquiry into the communication failure
on a SpiceJet flight from Kolkata to Chennai that had controllers in Kolkata on
Flight SG 7052
took off from Kolkata at 12.15am on Sunday. After flying for 33 minutes, it
suddenly went incommunicado at 12.48am. Though the flight could be tracked on
the radar, controllers were unable to speak to the pilots. They tried an
emergency frequency and another one reserved for communication between pilots
of different flights but there was no response.
The pilots on the SpiceJet aircraft were either unable to hear us or
not able to transmit the response
“We could see the
plane on the monitor. But we could not pass any instruction to the pilots. The
VHF system at our end was perfect because we were communicating with other
planes. The pilots on the SpiceJet aircraft were either unable to hear us or
not able to transmit the response,” said an official.
It was at 1.40am
that the ATC at Vizag informed the controllers in Kolkata that they had
established contact with the plane.
The DGCA probe will check
how the radio link was lost and how it was re-established.
