What is the need for expanding the regional air connectivity in India? In this context, discuss the government's UDAN Scheme and its achievements.

Why regional air connectivity

Metro-to-metro aviation already works on density. The need is elsewhere. North-eastern States, Himachal, Uttarakhand, J&K, the island territories and the tribal centre lose doctors, investors and tourists to a two-day road. Air links cut perishable time for horticulture and medical evacuation. They support balanced regional growth so that a second-rung city can hold a firm that would otherwise sit in Bengaluru. They are also a strategic layer: a civilian airport that can take a ATR or a small jet is a backup strip in a border State. Rail and highway remain the mass mode. Aviation is the thin, high-value mesh. Without subsidy, those thin routes die, because a full-fare Airbus cannot live on forty seats.

• Peg: Last-mile for the Northeast, hills and islands is the core public-need case, not another Delhi–Mumbai frequency.
• Peg: Tourism, organs, pharma cold chain and administrative travel are the economic case.

How UDAN works

UDAN / RCS (Regional Connectivity Scheme), run by the Ministry of Civil Aviation with the Airports Authority of India, auctions routes. The winning airline gets a viability gap funding for a limited period, a cap on some fares, and extras such as reduced landing and parking at public airports. States are asked to join with GST and fuel concessions and to help with security and slots. The bargain is public money for a thin route, not a permanent nationalised airline.

• Peg: VGF plus a fare cap is the UDAN deal: the aam nagrik ticket is bought with a public top-up.
• Peg: State ATF/GST and land support decide whether a bid is only a Delhi PowerPoint.

Achievements and limits

Airports have been revived or built under the same political umbrella, including some civil enclaves. Several rounds of bidding have awarded routes to previously unserved or underserved airports; new airports and revived strips have entered the map in the hills and the Northeast; helicopter and seaplane windows were opened for terrain that cannot take a jet. Some routes sustained after VGF, which is the real success. Many others lapsed when an airline exited or traffic did not appear. UDAN has thickened the map. A route is still not a region until catchment roads, tourism and a second operator exist.

• Peg: Lapsed routes are part of the record; counting only inaugural flights would over-claim.
• Peg: The scheme is a market-plus-subsidy experiment, not a finished grid.
