ABOUT AIRPORT AUTHORITY OF INDIA• 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 126 airports, which include 11 international airports, 89 domestic airports and 26 civil enclaves at Defence airfields.

• AAI provides air navigation services over 2.8 million square nautical miles of airspace. During the year 2002-03,

• AAI at various airports handled about 5 lakhs aircraft movements (4 lakhs domestic and 1 lakh international);40 million passengers (26 million domestic and 14 million international) and 9 lakh tonnes of cargo (3 lakh domestic and 6 lakh international).

There are basically two types of radar S-band radar :- Range -50 NM.

Frequency – 2.7 to 2.9 GHz. L-band radar :-Range – 200 NM.

Frequency – 1.1 to 1.3 GHz.

COMMUNICATION SYSTEM These elements cover ground to air and ground to ground communication. Enables the pilot to communicate with the controller in ATCS. High frequency (H.F) : Not in use now a days.

But forms the basis of VHF communication system. Frequency : 3 to 30 MHz.

Very high frequency (V.H.F) : It has different frequencies for communication of ground staff with aircrafts. Frequency : 118 to 136 MHz.

Ground frequency : 121.9 MHz. Tower frequency : 118.1 MHz. Approach frequency : 127.1 MHz.

LAN A (master LAN). LAN B (backup LAN). LAN C (DRA LAN).

Hardware and interface description: It consists of three Ethernet

switches. Built-in 10/100/1000 Ethernet port for LAN A. Either Built-in 10/100/1000 Ethernet port or a

10/100/1000 Ethernet PCI adapter (mounted within SUN processor) for LAN B

Each LAN connection is connected via a category 5 e cable with a RJ-45 connector.

Software description: Controlled by network operating system (NOS) software. It is a layer on top of the UNIX multi-tasking operating system. NOS executes in every subsystem except the DMS subsystem. NOS provide services to the application software in the following areas –

System service interface: It provides interface b/w application or system tasks and the services supported by NOS. It translates to UNIX system calls or library calls.

Common n/w service elements: It supports communications b/w the subsystems that are connected by LANs.

Time distribution and maintenance: Periodically interrogates TRS for current date and time and distributes to all subsystems on LAN.

I/O controllers: It contains services that allows application tasks to interface with external devices ( i.e. radar interface).

Task environment services: It contains services that provide an environment that permits application tasks to execute as independent entities.

Printer Services: It provides n/w access to flight strip printers (FSPs) and page printers.

CONCLUSION

• Automation system forms the nerves of the airport without which the very existence of airport is impossible.

• During our training period we got an opportunity to see many of the equipments like the radar, VOR, DME, ILS, AUTOMATION SYSTEM etc.
