The Directorate-General of Civil Aviation will inquire into an Air Traffic Control monitor suffering technical glitches soon after President Pratibha Patil's aircraft took off from the Kolkata airport on Thursday morning.
The aircraft never lost contact with the ATC while flying to Aizawl and was put on an alternative radio frequency immediately after the ATC monitor suffered the snag, the Civil Aviation Ministry said on Friday.
The DGCA would go into how the monitor of the Area Western Radar went blank for over three minutes soon after the aircraft took off from the Kolkata airport, a Ministry spokesperson said here.
“The President's aircraft was never out of ATC contact. While one display monitor had developed glitches, the plane was immediately put on another monitor with a separate frequency. In three minutes, the first one was also repaired,” the spokesperson said.
Kolkata airport sources said the ATC had remained in touch with the crew through radio signals.
The flight, which was over the Bagdogra airspace 10 minutes after takeoff, was put on a monitor in the Area Eastern Radar after the western radar suffered a malfunction.
