Kolkata: The last-mile cable disruption that severed critical radar feed to Kolkata airport for 13 hours on Saturday has forced Airports Authority of India (AAI) to scramble for new measures to secure the vulnerable point that can ground a hi-tech air traffic service and compromise flight safety.
Feed from radars is a crucial tool for traffic controllers to monitor aircraft and direct them safely. If the feed is cut off, as it did on Saturday, controllers virtually turn blind as dots representing planes in a defined section of the sky disappear from the monitor screen.
According to the top man at the communication, navigation and surveillance (CNS) wing of AAI in Kolkata, three specific measures have been proposed to secure the vital final leg of cable network that carries feeds from nine radars and eight associated aircraft positioning equipment situated across east and north-east India to Kolkata airport.
