3. INTRODUCTION OF AAI
 Airports Authority of India (AAI) under Ministry of Civil Aviation
was constituted by an Act of Parliament and come into being
on 1st April 1995 By meraging erstwhile NAA (National Airports
Authority) and IAAI ( International Airports Authority of India).
 RESPONSIBILITY:
 Creating, upgrading and managing civil aviation infrastructure
both on the GROUND and AIRSPACE in the country.
 Provide Air Traffic Management (ATM) services over Indian
airspace and adjoining oceanic areas.

4.  CNS
 Traffic Control For Airport(ATC).
 Maintenance Of Passenger Terminals.
 Cargo Terminal At International And Domestic.

9. COMMUNICATION
 HF or VHF is used for communication between
controller and pilot.
 Aeronautical Fixed Telecommunication Network
(AFTN) is used for communication among Ground
Stations.
 AMSS stands for Automatic Message Switching
System and works on the principle of “Store and
Forward”.
 Communication is the exchange of voice and data
information between the pilot and air traffic
controllers or flight information canters.

10. COMMUNICATION(VHF)
Communications is done through V.H.F(very
high frequency range).
 The range of VHF is 30 MHz to 300 MHz.
 It is a type of line of sight communication.
 Modulation technique used in Amplitude Modulation.
 Allotted frequency for V.H.F is 108-156 MHz .
 Out of it A.A.I operates in 117.975 MHz – 136 MHz .
 Each airport has its designated frequency

11. VHF TRANSMITTER
•A transmitter uses an oscillator to produce the desired
radio frequency current.
•Crystal-controlled oscillators are normally employed to
provide better frequency stability. Thinner the crystal,
higher will be the operating frequency.

12. VHF RECEIVER
•The VHF receiver has the function of selecting the desired
signal at VHF frequencies from all the other unwanted
signals, amplifying and demodulating it, and reproducing it
in the actual shape/desired manner

13. VOR ( VHF Omini Range)
ILS ( Instrument Landing System)
• Localizer
• Glidepath
• Marker Beacons
DME (Distance Measuring Equiment)
• High Power
• Low Power
NDB (Non Directional Beacon)
GAGAN( GPS Aided GEO Augmented Navigation)

ADS-B ( Automatic depedent survellance
Broadcast)
ASMGCS (Advance surface movement
guidance controlling system)
SMR (Surface movement radar)
MLAT (Multi lateration system)
Automation System.

16. RADAR
•Radars are employed
throughout the world for the
purpose of safely controlling air
traffic en-route and in the vicinity
of airports.
•Aircraft as well as vehicular
traffic at large airports are
monitored by means of high-
resolution radar
RADIO DETECTION AND RANGING

17. SECURITY X-RAY BIS
 The luggage carried
by the passengers is
checked by using the
X-Ray Baggage
Inspection System
 X-ray BIS is used to
detect the presence
of metal and
explosive material.

 ILS
 LOCALIZER
 GLIDEPATH
 GAGAN

19. CONCULATION
 Very enriching experience.
 Practical applications of theoretical
concepts in form of various equipment's and
processes.
 Cooperative and encouraging staff make it
true learning experience.
