The radar to monitor aircraft movement on the ground at Calcutta airport has been malfunctioning since one of its components got damaged on Thursday, airport sources said.
Airport officials said one of the 12 multilateration system equipment of the Advanced Surface Movement Guidance and Control System got damaged on Wednesday while an abandoned watch tower was being demolished.
“Aircraft movement on the ground is being monitored manually,” an airport official said on Friday. The equipment sends pictures and data of an aircraft to the radar monitor.
“Since all 12 equipment are interlinked, the system is malfunctioning,” he said.
The radar helps the air traffic control keep watch on an aircraft when it takes off or goes to the parking bay after landing. “On a clear day monitoring of aircraft can be done without the radar. But there’ll be a problem if there is fog. And most mornings during winter are foggy,” the official pointed out.
The radar was made operational in September 2011.
