The long-standing plan to build a greenfield airport at Hosur in Tamil Nadu has once again hit a roadblock, while neighbouring Andhra Pradesh is quietly moving forward with its own aviation plans at Kuppam. This contrast has sparked widespread debate, especially because both locations lie close to Bengaluru, a major aviation hub.

Union Civil Aviation Minister Kinjarapu Rammohan Naidu informed the Rajya Sabha that the Hosur airport proposal sent by the Tamil Nadu government has not been recommended. The reason, he said, is that the airspace over Hosur is required for national defence projects carried out by Hindustan Aeronautics Limited (HAL).

Defence Airspace a key constraint

Responding to questions raised by DMK MPs S. Kalyanasundaram and Kanimozhi N.V.N. Somu, the minister explained that the Hosur region falls under HAL-controlled airspace, which is extensively used for military operations and test flights. Because of this, civilian aircraft operations are currently not considered feasible. The Ministry of Defence has maintained this position repeatedly, including in its latest rejection in January, dealing another setback to Tamil Nadu’s plans.

Why Hosur matters to Tamil Nadu

The proposed Hosur airport is planned across nearly 2,979 acres in the Berigai–Bagalur–Shoolagiri belt, covering 12 villages in Hosur and Shoolagiri taluks. The Tamil Nadu government views the airport as critical infrastructure for Hosur, a rapidly growing industrial hub with more than 500 large industries and around 3,000 MSMEs.

In November last year, the Tamil Nadu Industrial Development Corporation (TIDCO) sent a site clearance proposal, which was circulated to the Airports Authority of India (AAI), the Directorate General of Civil Aviation (DGCA), and the Ministry of Defence. Even after an initial rejection in June due to airspace constraints, the State government made fresh representations and is preparing to resubmit its case.

Hosur is located about 40–45 km from Bengaluru’s Kempe Gowda International Airport (KIA), making it a natural alternative airport for south Bengaluru and northern Tamil Nadu, similar to how Navi Mumbai airport is expected to ease pressure on Mumbai.

Andhra Pradesh advances with Kuppam

While Hosur remains stuck at the clearance stage, Andhra Pradesh has moved forward with feasibility studies for new airports. According to a recent media report, the Airports Authority of India has completed pre-feasibility studies for proposed airport sites at Kuppam, Srikakulam, and Ongole.

Site clearance proposals for Kuppam and Srikakulam are currently under consideration under the Greenfield Airports (GFA) Policy. Kuppam is located about 90–100 km from Bengaluru and lies close to the Tamil Nadu–Karnataka border. Many travellers from Kuppam, Hosur, and nearby areas currently depend on Bengaluru airport.

Aviation experts say that once a Kuppam airport becomes operational, some of this passenger traffic could shift away from Bengaluru, reducing its dominance and strengthening regional connectivity on the Andhra Pradesh side.

The stalled Hosur project and Andhra Pradesh’s progress have triggered strong reactions on social media. Many users have linked the delay to broader political developments and expressed concern that Hosur’s industrial importance is being overlooked.

A recent report by Dinamalar further fuelled the discussion by suggesting that developments outside Tamil Nadu may be indirectly affecting the Hosur plan. While these views are opinion-driven and not officially verified, they reflect growing frustration and a widening gap between official explanations and public perception.

Policy limits and proximity

Under the Greenfield Airports Policy of 2008, no new airport is normally allowed within a 150-km aerial distance of an existing civilian airport, unless approved on a case-by-case basis after an impact assessment. Hosur’s close proximity to Bengaluru airport, combined with HAL’s operational requirements, places it in a particularly complex policy zone.

Kuppam, although also within the wider Bengaluru catchment area, faces fewer airspace-related constraints, giving Andhra Pradesh a relatively clearer path forward.

For now, Hosur’s airport dream remains grounded, pending a breakthrough on defence clearances. Andhra Pradesh, meanwhile, is still at the feasibility stage for Kuppam, with timelines dependent on land acquisition, approvals, and funding.

Whether this moment becomes Andhra Pradesh’s opportunity or remains only a temporary divergence will depend on how quickly Tamil Nadu can navigate regulatory and strategic hurdles. What is clear is that in a region hungry for better connectivity, every delay reshapes the aviation map and the political conversation around it.
