The Airports Authority of India (AAI) under the Ministry of Civil Aviation is
responsible for creating, upgrading, maintaining and managing civil aviation
infrastructure in India. It provides Air traffic management (ATM) services over
Indian airspace and adjoining oceanic areas. It also manages a total of 125
Airports, including 11 International Airports, 8 Customs Airports, 81 Domestic
Airports and 25 Civil enclaves at Military 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 89VOR/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.
AAI's implementation of Automatic Dependence Surveillance System (ADSS), using
indigenous technology, 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 and are likely to be
implemented at other Airports in a phased manner. AAI is implementing
the GAGAN project in technological collaboration with the Indian Space Research
Organization (ISRO), where the satellite based system will be used for navigation.
The navigation signals thus received from the GPS will be augmented to achieve
the navigational requirement of aircraft. First phase of technology demonstration
system was completed in February 2008.
AAI has four training establishments viz. The Civil Aviation Training College (CATC)
at Allahabad, National Institute of Aviation Management and Research (NIAMAR)
at Delhi and Fire Training Centres (FTC) at Delhi & Kolkata. An Aerodrome Visual
Simulator (AVS) has been provided at CATC and non-radar procedural ATC
simulator equipment is being supplied to CATC Allahabad and Hyderabad Airport.
AAI has a dedicated Flight Inspection Unit (FIU) with a fleet of three aircraft fitted
with flight inspection system to inspect Instrument Landing Systems up to Cat-III,
VORs, DMEs, NDBs, VGSI (PAPI, VASI) and RADAR (ASR/MSSR). In addition to in-
house flight calibration of its navigational aids, AAI undertakes flight calibration
of navigational aids for the Indian Air Force, Indian Navy, Indian Coast Guard and
other private airfields in the country.
AAI has entered into Joint
Ventures at Mumbai, Kolkata, Delhi, Hyderabad, Bangalore and Nagpur Airports to
upgrade these airports.
Airports Authority of India (AAI) was constituted by an Act of Parliament and came
into being on 1 April 1995 by merging erstwhile National Airports Authority and
International Airports Authority of India. The merger brought into existence a
single Organization entrusted with the responsibility of creating, upgrading,
maintaining and managing civil aviation infrastructure both on the ground and air
space in the country.
Design, Development, Operation and Maintenance of international and domestic
airports and civil enclaves.
Control and Management of the Indian airspace extending beyond the territorial
limits of the country, as accepted by ICAO.

management of cargo terminals, development & maintenance of apron
infrastructure including runways, parallel taxiways, apron etc.,
Provision of Communication, Navigation and Surveillance which includes provision
of DVOR / DME, ILS, ATC radars, visual aids etc., provision of air traffic services,
provision of passenger facilities and related amenities at its terminals thereby
ensuring safe and secure operations of aircraft, passenger and cargo in the
In tune with its global approach to modernise Air Traffic Control (ATC)
infrastructure for seamless navigation across state and regional boundaries,
AAI is upgrading to satellite based Communication, Navigation, Surveillance
(CNS) and Air Traffic Management.
A number of co-operation agreements and memoranda of co-operation have
been signed with the Federal Aviation Administration, US Trade &
Development Agency, European Union, Air Services Australia and the French
Government Co-operative Projects and Studies initiated to gain from their
Through these activities more and more executives of AAI are being exposed
to the latest technology, modern practices & procedures being adopted to
improve the overall performance of Airports and Air Navigation Services.
Some of the major initiatives in this direction are introduction of Reduced
Vertical Separation Minima (RVSM) in Indian air space to increase capacity
and reduce congestion in the air; implementation of GPS And Geo Augmented
Navigation (GAGAN) jointly with ISRO which when put to operation would
be one of the four such systems in the world.
AAI is a full member of the Civil Air Navigation Services
AAI website is a website giving a host of information about the organization
besides domestic and international flight schedules and such other information of
interest to the public in general and passengers in particular.
AAI has a number of training establishments, viz. NIAMAR in Delhi, CATC in
Allahabad, Fire Training Centres at Delhi & Kolkata for in-house training of its
engineers, Air Traffic Controllers, Rescue & Fire Fighting personnel etc.
NIAMAR & CATC are members of ICAO TRAINER programme under which
they share Standard Training Packages (STP) from a central pool for imparting
training on various subjects. Both CATC & NIAMAR have also contributed a
number of STPs to the Central pool under ICAO TRAINER programme. Foreign
students have also been participating in the training programme being conducted
by these institution
Most of AAI's revenue is generated from landing/parking fees and fees collected
by providing CNS & ATC services to aircraft over the Indian airspace.
Only 16 of the 126 airfields operated by the AAI are profitable while the other
airports incur heavy losses due to under utilisation and poor management.
Privatization of Airports
The AAI was involved in a tussle with the Ministry of Civil Aviation over the issue of privatisation of
its two most profitable airports at Delhi and Mumbai.
The Government of India handed over these two airports to private
companies for the purpose of modernization in 2006 under revenue
sharing agreement to the GMR Group and GVK group respectively.
the Nagpur Airport was transferred to the Maharashtra State
In addition to these, several greenfield airports are being operated by
Private consortiums, namely, Bengaluru International Airport, Kazi
Nazrul Islam Airport at Durgapur in West Bengal, Rajiv Gandhi
International Airport at Hyderabad and Cochin International Airport.
International ProjectsThe AAI has been involved in various consultancy projects
with Libya, Algeria, Yemen, Maldives, Nauru and Afghanistan The AAI
also provides trained personnel for operation, maintenance and
management of airports in these countries
