Initially, the state government had identified four potential sites for the proposed airport—Parandur, Pannur, Thiruporur and Padalam. Following a feasibility study conducted by the AAI, Parandur and Pannur emerged as the most suitable locations. Following recommendations from the AAI, Parandur was ultimately selected as the site for the airport, taking into account several factors outlined by the Tamil Nadu Industrial Development Corporation (TIDCO), the nodal agency overseeing the project. As per the pre-feasibility study carried out by TIDCO …“Based on the AAI’s recommendation, due diligence, and consideration of factors such as land availability, travel distance, infrastructure development cost, airspace availability and existing obstacles around site, the government of Tamil Nadu finalised the site at Parandur for the development of the greenfield airport.”
