"We are awaiting a report from the Tamil Nadu government regarding land acquisition. We are likely to get the report in the next two to three weeks. As soon as we get the report, we will move the Union Cabinet on modernisation of Kolkata and Chennai airports", Ashok Chawla, civil aviation secretary said.

He said the West Bengal government has already made it clear that the Kolkata airport would be modernised by the Airports Authority of India.

Earlier, addressing the inaugural session of the exhibition, AAI chief K Ramalingam said major Indian airports in future would have "intelligent terminals" fitted with sensors to operate various facilities - from lighting and air-conditioning to an IT-enabled building management system.

High-tech equipment would be deployed for the security and air traffic control systems covering a wide range of activities - from access control to perimeter security.

The communication, navigation, surveillance and air traffic management system would be modernised and linked to the satellite-based system called GAGAN, in collaboration with the Indian Space Research Organisation.
