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 a total of 133 airports out of which 110 airports are operational while other 23 airports are non-operational. These operational airports include 28 civil enclaves and 8 airports under private control [2 JV Airports + 6 PPP Airports under long term lease]. 35 out of total 110 AAI operational airports have international operations. AAI provides air navigation services over 2.8 million square nautical miles of air space. During the year 2023-24, AAI at its airports (excluding JV and PPP Airports) handled aircraft movement of 1053.96 Thousand [International 103.75 & Domestic 950.21], Passengers handled 130.67 Million [International 15.09 & Domestic 115.58] and the Freight handled 688.38 thousand MT [International 338.85 & Domestic 349.53]. Further, all Indian airports taken together have handled aircraft movement of 2677.59 Thousand [International 425.17 & Domestic 2252.42], Passengers handled 376.43 Million [International 69.64 & Domestic 306.79] and the Freight handled 3365.68 thousand MT [International 2045.51 & Domestic 1320.17]. Passenger FacilitiesThe 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. Air Navigation ServicesIn 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. SecurityThe 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. Aerodrome FacilitiesIn 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. HRD TrainingA large pool of trained and highly skilled manpower is one of the major assets of Airports Authority of India. Development and Technological enhancements and consequent refinement of operating standards and procedures, new standards of safety and security and improvements in management techniques call for continuing training to update the knowledge and skill of officers and staff. For this purpose 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 IT ImplementationInformation Technology holds the key to operational and managerial efficiency, transparency and employee productivity. AAI initiated a programme to indoctrinate IT culture among its employees and this is most powerful tool to enhance efficiency in the organization. AAI website with domain name www.aai.aero is a popular website giving a host of information about the organization besides domestic and international flight information of interest to the public in general and passengers in particular. The functions of AAI are as follows: As an Airport Developer Design, Develop, Operate and Maintain international and domestic airports and civil enclaves in India. Expand and strengthen the operational area, viz. Runways, Aprons, Taxiways etc. Construct, Modify and Manage the passenger terminals and other airport facilities. Develop and manage the cargo terminals (through its subsidiary - AAI Cargo Logistics and Allied Services Company Limited). Ensure provision of passenger facilities and information system. As an Air Navigation Service Provider Control and manage the Indian airspace extending beyond the territorial limits of the country, as accepted by ICAO. Ensure the safety and efficiency of flights. Make provision for cutting edge technology for Communication Navigation and Surveillance of the Indian airspace.
