Airports Authority of India (AAI) manages a total of 125 Airports, which include 11 International Airports, 08 Customs Airports, 81 Domestic Airports and 25 Civil Enclaves at Defence Airfields. AAI also provides Air Traffic Management Services (ATMS) over entire Indian Air Space and adjoining oceanic areas with ground installations at all Airports and 25 other locations to ensure safety of Aircraft operations.
The Airports at Ahmedabad, Amritsar, Calicut, Guwahati, Jaipur, Trivandrum, Kolkata & Chennai, which today are established as International Airports, are open to operations even by Foreign International Airlines. Besides, the International flights, National Flag Carriers operate from Coimbatore, Tiruchirappalli, Varanasi, and Gaya Airports. Not only this but also the Tourist Charters now touch Agra, Coimbatore, Jaipur, Lucknow, Patna Airports etc.
AAI has entered into a Joint Venture at Mumbai, Delhi, Hyderabad, Bangalore and Nagpur Airports to upgrade these Airports and emulate the world standards.
All major air-routes over Indian landmass are Radar covered (29 Radar installations at 11 locations) along with VOR/DVOR coverage (89 installations) co-located with Distance Measuring Equipment (90 installations). 52 runways are provided with ILS installations with Night Landing Facilities at most of these Airports and Automatic Message Switching System at 15 Airports.
AAI's successful implementation of Automatic Dependence Surveillance System (ADSS), using indigenous technology, at Calcutta and Chennai Air Traffic Control Centres, gave India the distinction of being the first country to use this advanced technology in the South East Asian region thus enabling effective Air Traffic Control over oceanic areas using satellite mode of communication. Use of remote controlled VHF coverage, along with satellite communication links, has given added strength to our ATMS. Linking of 80 locations by V-Sat installations shall vastly enhance Air Traffic Management and in turn safety of aircraft operations besides enabling administrative and operational control over our extensive Airport network. 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 phased manner.
AAI has undertaken GAGAN project in technological collaboration with Indian Space and 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 aircrafts. First Phase of technology demonstration system has already been successfully completed in February 2008. Development team has been geared up to upgrade the system in operational phase.
AAI has also planned to provide Ground Based Augmentation System (GBAS) at Delhi and Mumbai Airports. This GBAS equipment will be capable of providing Category-II (curved approach) landing signals to the aircrafts thus replacing the existing instrument landing system in the long run, which is required at each end of the runway.
The Advanced Surface Movement Guidance and Control System (ASMGCS), installed at Delhi, has upgraded operation to runway 28 from CAT-IIIA level to CAT-IIIB level. CAT-IIIA system permits landing of aircrafts up to visibility of 200mtrs. However, CAT-IIIB will permit safe landing at the Airports at a visibility below 200mtrs but above 50mtrs.
AAI's endeavour, in enhanced focus on 'customer's expectations', has evinced enthusiastic response to independent agency, which has organised customer satisfaction surveys at 30 busy Airports. These surveys have enabled us to undertake improvements on aspects recommended by the Airport users. The receptacles for our 'Business Reply Letters' at Airports have gained popularity; these responses enable us to understand the changing aspirations of Airport users. During the first year of the millennium, AAI endeavours to make its operations more transparent and also make available the instantaneous information to customers by deploying state-of-art Information Technology.
Airports Authority of India (AAI) was constituted by an Act of Parliament and came into being on 1st 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.
AAI manages 125 airports, which include 11 International Airport, 08 Customs Airports, 81 Domestic Airports and 27 Civil Enclaves at Defense airfields. AAI provides air navigation services over 2.8 million square nautical miles of air space. During the year 2008- 09, AAI handled aircraft movement of 1306532 Nos. [International 270345 & Domestic 1036187], Passengers handled 44262137 Nos. [International 1047614 & Domestic 33785990] and the cargo handled 499418 tons [International 318242 & Domestic 181176].
1. Passenger Facilities
The main functions of AAI inter-alia include construction, modification & management of passenger terminals, development & 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 country.
2. Air Navigation Services
In tune with global approach to modernization of Air Navigation infrastructure for seamless navigation across state and regional boundaries, AAI has been going ahead with its plans for transition to satellite based Communication, Navigation, Surveillance and Air Traffic Management. A number of co-operation agreements and memoranda of co-operation have been signed with US 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 experience. 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.
Induction of latest state-of-the-art equipment, both as replacement and old equipments and also as new facilities to improve standards of safety of airports in the air is a continuous process. Adoptions of new and improved procedure go hand in hand with induction of new equipment. Some of the major initiatives in this direction are introduction of Reduced Vertical Separation Minima (RVSM) in India air space to increase airspace 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.
The continuing security environment has brought into focus the need for strengthening security of vital installations. There was thus an urgent need to revamp the security at airports not only to thwart any misadventure but also to restore confidence of traveling public in the security of air travel as a whole, which was shaken after 9/11 tragedy. With this in view, a number of steps were taken including deployment of CISF for airport security, CCTV surveillance system at sensitive airports, latest and state-of-the-art X-ray baggage inspection systems, premier security & surveillance systems. Smart Cards for access control to vital installations at airports are also being considered to supplement the efforts of security personnel at sensitive airports.
4. Aerodrome Facilities
In Airports Authority of India, the basic approach to planning of airport facilities has been adopted to create capacity ahead of demand in our efforts. Towards implementation of this strategy, a number of projects for extension and strengthening of runway, taxi track and aprons at different airports has been taken up. Extension of runway to 7500 ft. has been taken up to support operation for Airbus-320/Boeing 737-800 category of aircrafts at all airports.
