3. AIRPORTS AUTHORITY OF INDIA (AAI)
• Formed under the act of parliament- AIRPORTS AUTHORITY OF INDIA
ACT 1994.
• Organization under the Ministry of Civil Aviation that manages all the
airports in India.
• Major revenue is generated from airports development, landing/parking
fees and fees charged for providing Air Traffic Control services to aircraft
over the Indian airspace.

4. FUNCTIONS OF AAI
• Control and management of the Indian air space.
• Installation and maintenance of various communication, navigation and
surveillance aids.
• Design, development, operation and maintenance of passenger terminals.
• Development and management of cargo terminals.
• Passenger facilities and information system.
• Rescue and fire services.
• Anti-Hijacking cell.

5. AIR TRAFFIC CONTROL
• Air traffic control (ATC) is a service provided by ground based
Controllers who direct the Aircraft on the ground and through
controlled Air Space and can provide advisory Services to aircraft in
non-controlled Air Space.
• To prevent collisions ATC enforces Traffic Separation Rules, which
Ensure each aircraft Maintains a Minimum amount of Empty space
around it all times.

7. ATC
• A wing of AAI.
• Provides control over air traffic.
• Decides air-routes over Indian airspace.
• Responsibilities also includes
1.) Area flight information.
2.) Notice to air-men (NOTAM)
3.) Communication services.
4.) Navigational services.
5.) Surveillance services.

9. NAVIGATION OR NAV-AIDS
• It is a process of reading and controlling the movement of an aircraft
from one place to another.
• NDB: Transmits guiding signals towards a particular aircraft at a
particular frequency.
• DVOR: Directional VHF Omni-range measures the angular orientation
of the aircraft with respect to the magnetic north.
• DME: Gives the slant distance of the aircraft from the equipment.

10. NAVIGATION OR NAV-AIDS
• CDI: Guiding signals received by avionics of the aircraft are indicated to pilot
through Course Deviation Indicator (CDI) needles.
• ILS: Instrument Landing System which helps the aircraft to land safely and includes.
• Localizer: provides runway centre line guidance to aircraft.
• Glide Path: Provides Gliding angle to the aircraft.
• Markers: Provides runway threshold to the aircraft.
• Air Traffic Control: Air traffic controllers in direct contact with the pilots and guide
them to move forward.

16. VHF
• The VHF (very high frequency) range of Radio Spectrum is the band
which extends from 30 MHz to 300 Mhz.
• Band used for communication at the airport is 118- 136 MHz.
• Ideal for short distance terrestrial communication practically at LOS.
• Less affected by atmospheric noise and interference from electrical
equipment.
• Easily blocked by land features than HF.

17. RADAR
PRIMARY:
• No role of target.
• Detection range up to 60NM.
• Frequency range is between 2 to 4 GHz.
• Operates at 15RPM.
• Consumes more power.
28-07-2018 28-07-2018 17

18. RADAR
SECONDARY:
• Target has to participate in the detection process.
• Target uses a transponder to reflect signal back.
• Detection range is up to 220 NM.
• Frequency range is between 1 to 2 GHz.
28-07-2018 28-07-2018 18

19. AUTOMATIC MESSAGE SWITCHING SYSTEM
(AMSS)
• Accurate and speedy exchange of aeronautical information, such as Air
Traffic Service (ATS) messages consisting of Flight Plan, Departure and
Estimates messages etc. between stations to enable them to control the
air space and movement of Air traffic in an orderly manner Network
Topology.
• All networking within AAI is established mainly using three topologies
which are
• 1.)Mesh : Fully connected
• 2.)Bus : Main cable
• 3.)Star : Employees a hub

20. CONCLUSION
• Very enriching experience
• Practical application of theoretical concepts in form of various
equipments and processes
• Cooperative and encouraging staff makes it a true learning
experience
