Visakhapatnam: Defence ministry has agreed to fully operate the Naval airport, INS Dega, here from March 1. "Defence ministry has given its in-principle nod to run the airport. Initially, the ministry will manage the airport for 24 hours for three days and extend its operation further depending on traffic demand," Chairman of the Parliamentary Standing Committee on Science and Technology, Environment and Forests T Subbarami Reddy said. Once fully operational, the facility will cater to fliers from north coastal Andhra Pradesh. At present, the airport which is under Navy, is operational only for 12 hours a day and there is an increasing demand for extending flying hours in both civil and military spheres.
