Kurnool: Chairman of the parliamentary committee on civil aviation TG Venkatesh said that air connectivity to tier-2 cities in Andhra Pradesh would improve tourism as 40 RCS-UDAN routes have been identified. Of them, 28 have been operationalised. Efforts are on to convince airline operators to commence flight services, he said, and added that Kurnool-Vijayawada and Vijayawada-Nagarjunasagar routes are yet to be made functional. The committee has recommended enhancing low-cost regional air connectivity by promoting helicopter operations in the country, he said. It also recommended formulating a ‘seaplane policy’.
