What Happened
- The government has announced modifications to the UDAN (Ude Desh ka Aam Nagrik) regional connectivity scheme, with a ₹30,000-crore proposed outlay, focusing on two key changes: making airports financially sustainable and extending the Viability Gap Funding and Financing (VGFF) period for regional airlines.
- The revised scheme allocates ₹18,000 crore for new airport development — including greenfield airports, airstrip refurbishment, and heliports in hilly and remote areas — and ₹12,000 crore for Viability Gap Funding (VGF) to support airlines on unviable regional routes.
- The modification extends UDAN's framework beyond April 2027 and aims to add 120 new regional destinations, targeting 4 crore additional passengers over the next 10 years.
- Sustainability concerns persist: without viable passenger demand on many thin routes, airports risk being built faster than sustainable airline services can be established.

UDAN Scheme — Origin and Architecture
UDAN (Ude Desh ka Aam Nagrik — "Let the common citizen of the country fly") is India's Regional Connectivity Scheme (RCS) launched on October 21, 2016, under the National Civil Aviation Policy (NCAP) 2016 by the Ministry of Civil Aviation. The scheme aims to connect Tier-2 and Tier-3 cities through a financially supported model, making air travel affordable by capping fares on regional routes.
- UDAN is jointly funded by the Central Government, state governments, and airport operators.
- Airlines operating under UDAN receive Viability Gap Funding (VGF) to compensate for losses on thin regional routes — funded 80% by the Centre and 20% by concerned state governments.
- Concessions to UDAN operators: AAI waives landing/parking charges; ATF excise duty capped at 2% for first three years at RCS airports; state VAT on ATF reduced to 1% or less.
- As of 2025, over 519 routes have been operationalised under UDAN including tourism and helicopter routes.
- Approximately 135+ airports/airstrips have been revived or connected under UDAN since launch.
Connection to this news: The modification addresses UDAN's core structural weakness — VGF support was time-limited (typically 3 years per route), after which airlines withdrew from many routes once subsidies ended. The extended VGFF period aims to keep airlines on routes longer to allow demand to mature.
Viability Gap Funding — Mechanism and Role in Infrastructure Policy
Viability Gap Funding (VGF) is a government grant mechanism used to make commercially unviable but socially necessary projects financially attractive for private investment. In infrastructure, VGF bridges the gap between the cost of a project and its commercial revenues, enabling private operators to participate in public-interest ventures they would otherwise avoid.
- VGF is governed by the Scheme for Financial Support to Public Private Partnerships in Infrastructure (2006), administered by the Department of Economic Affairs.
- In UDAN, VGF is calculated per available seat kilometre (ASK) on designated regional routes, compensating airlines for the difference between costs and revenues.
- Beyond aviation, VGF is used in roads, ports, railways, urban water supply, and health sectors.
- The modification extends the VGFF period — giving airlines longer financial runway to establish route viability before subsidies taper off.
- Longer VGF tenure also incentivises airlines to acquire appropriate aircraft (ATR 72, Q400 turboprops) suited to short-haul, lower-demand routes.
Connection to this news: The key innovation in the modified UDAN is recognising that 3 years of VGF is insufficient for thin routes to become self-sustaining. Extending the VGFF period attempts to address the high route dropout rate that has plagued UDAN since its launch.
Airport Infrastructure and Public–Private Partnership in Civil Aviation
India's airport infrastructure has grown rapidly through Public-Private Partnership (PPP) models. Major airports (Delhi, Mumbai, Hyderabad, Bangalore, Cochin) are operated by private concessionaires under AAI or state government ownership frameworks. Regional airports remain largely under the Airports Authority of India (AAI), which faces revenue constraints from thin route traffic.
- AAI operates approximately 137 airports in India; many smaller regional airports run at losses due to low passenger volumes.
- The modified UDAN's ₹18,000-crore airport development allocation includes greenfield airports (in previously unconnected areas), refurbishment of existing airstrips (many built by the British-era or state governments), and heliports in hilly/North-East districts.
- Cochin International Airport (CIAL) is the world's first fully solar-powered airport — a model for airport sustainability referenced in the modified UDAN's sustainability focus.
- UDAN has a specific component for North-Eastern states and hilly terrain (helicopter routes, seaplane routes) to connect areas where fixed-wing operations are unviable.
Connection to this news: Airport sustainability — ensuring that airports built under UDAN generate enough non-aeronautical revenue (retail, cargo, fuel) to cover operating costs — is the new focus because many UDAN airports are running at structural losses, threatening the scheme's long-term viability.
