The Airports Authority of India or AAI is a statutory body,[4][5][6] under the jurisdiction of Directorate General of Civil Aviation, Ministry of Civil Aviation, Government of India. It is responsible for creating, upgrading, maintaining and managing civil aviation infrastructure in India. It provides Communication Navigation Surveillance / Air Traffic Management (CNS/ATM) services over Indian airspace and adjoining oceanic areas. AAI is currently managing a total of 137[7] Airports, including 23[7] International Airports, 10 Customs Airports, 81 Domestic Airports and 23 Civil enclaves at Defense Airfields. AAI also has ground installations at all airports and 25 other locations to ensure safety of aircraft operations. AAI covers all major air-routes over Indian landmass via 29 Radar installations at 11 locations along with 700 VOR/DVOR installations co-located with Distance Measuring Equipment (DME). 52 runways are provided with Instrument landing system (ILS) installations with Night Landing Facilities at most of these airports and Automatic Message Switching System at 15 Airports.


The Government of India constituted the International Airports Authority of India (IAAI) in 1972 to manage the nation's international airports while the National Airports Authority of India (NAAI) was constituted in 1986 to look after domestic airports.[8][9] The organisations were merged in April 1995 by an Act of Parliament, namely, the Airports Authority of India Act, 1994 and has been constituted as a Statutory Body and was named as Airports Authority of India (AAI).[10] This new organisation was to be responsible for creating, upgrading, maintaining and managing civil aviation infrastructure both on the ground and air space in the country.

Major ongoing projects[edit]

AAI's implementation of Automatic Dependence Surveillance System (ADSS) at Kolkata and Chennai Air Traffic Control Centres, made India the first country to use this technology in the South East Asian region thus enabling Air Traffic Control over oceanic areas using satellite mode of communication. Performance Based Navigation (PBN) procedures have already been implemented at Mumbai, Delhi and Ahmedabad Airports. AAI is implementing the GAGAN project in technological collaboration with the Indian Space Research Organisation (ISRO). The navigation signals thus received from the GPS will be augmented to achieve the navigational requirement of aircraft. The first phase of the technology demonstration system was completed in February 2008.

Organizational structure[edit]

AAI having its corporate headquarters at Rajiv Gandhi Bhawan, New Delhi is operating from its five regional headquarters namely-

  1. Eastern Regional Headquarter at Kolkata, West Bengal
