Airports Authority Of India

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 * 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 * of remote controlled VHF coverage, along with satellite communication links, has given added strength to *ing 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 Organisation (ISRO), where the satellite based system will be used for * 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 Read more
