This document summarizes a training seminar on the Airport Authority of India that was held at Jaipur Airport. It discusses the following key points: - The Airport Authority of India (AAI) is responsible for creating, upgrading, maintaining and managing India's civil aviation infrastructure including 126 airports. - AAI's main functions include air traffic control, maintenance of passenger and cargo terminals, and providing Communication, Navigation, and Surveillance (CNS) systems. - CNS systems discussed include navigation aids like ILS, DME, DVOR; communication systems; and surveillance equipment like radar and security screening tools. - The seminar provided valuable hands-on learning about AAI's

3. Introduction
• AAI IS AN ORGANISATION WORKING UNDER THE
MINISTERY OF CIVIL AVIATIONS.
• Formed on 1st April 1995 under the Act of
Parliament.
• Creates, upgrade, maintain & manages civil aviation
infrastructure.
• It manages a total of 126 Airports.

4. Main Functions Of AAI
 CNS
 TRAFFIC CONTROL FOR AIRPORT
 MAINTAINENCE OF PASSENGER TERMINALS
 CARGO TERMINAL AT INTERNATIONAL AND
DOMESTIC

6. COMMUNICATION
GROUND TO AIR GROUND TO GROUND
 Communication refers to sending, receiving and
processing of information by electronic means.
COMMUNICATION

7. COMMUNICATION
Ground to Ground: Communication among Stations
on Ground.
GroundTo Air: Between Pilot and the AirTraffic
Controller.
Air to Air : Between the Pilots of two aircrafts in the
air.

8. COMMUNICATION
 HF or VHF is used for communication between
controller and pilot.
 Aeronautical Fixed Telecommunication Network
(AFTN) is used for communication among Ground
Stations
 AFTN uses basic Copper Wire as communication
media.

9. Navigation
 Navigation is the 'ART' of determining the position of
an aircraft over earth's surface and guiding its
progress from one place to another.
 To accomplish this ART, some sort of ‘AIDS' are
required by the PILOTS.

10. Nav-Aids
 ILS: Instrument Landing System
 DME: Distance Measuring Equipment
 DVOR: Doppler VHF OMNI RANGE

11. INSTRUMENT LANDING
SYSTEM
 The Instrument Landing System (ILS) provides a
means for safe landing of aircraft at airports under
conditions of low ceilings and limited visibility.
 The use of the system materially reduces
interruptions of service at airports resulting from
bad weather by allowing operations to continue at
lower weather minimums.
 The ILS also increases the traffic handling capacity
of the airport under all weather conditions.

12. Instrument Landing System
 Guides the aircraft as to where to land on the
runway
 System comprises of two parts:
Localizer Glide Path

13. Localizer
 Used to find Centre Line of
runway.
 Uses LPDA
 Used Freq. Range is 108-112
MHz.
 Located at around 1200-1500
feet away from the end of Runway.
 Range : 10-20 NM

14. Glide Path
It gives the Glide angle i.e. Angle
Of Descent.
Range:- 10 NM(-8 to +8 degrees)
 Safe glide angle:- 2-4 degrees

19. DME : Distance Measuring Equipment
Aircraft use DME to determine their distance from a
land-based transponder

20.  DME is used in navigational aid which provide a pilot
with visual info regarding his position(distance)
related to ground base DME station.
 The frequency range
used for DME is between 960 MHz to
1215 MHz .This frequency is used
Because it has better frequency stability comparative to
next higher frequencies in microwave band. It has less
reflection and attenuation.
DME : Distance Measuring Equipment

21. DVOR : Doppler VHF Omni Range
 VHF Omni range measures the angular orientation
of the aircraft with respect to the Magnetic North.

22. V.H.F-OMNI RANGE
 Antenna System comprising
a ring of antennas.
 Alford loop Antenna.
 Range : 200 NM.

23. SURVEILLANCE
The act of watching or
monitoring the behavior
activities, or other
changing information.
Surveillance may be
applied to observation
from a distance by
means of electronic
equipment.

24. SURVEILLANCE
RADAR SECURITY
EQUIPMENTS
SURVEILLANCE

25. RADAR

26. 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.
 Radar has also been used to guide
aircraft to a safe landing in bad
weather.

27. SECURITY EQUIPMENT
 HAND HELD METAL DETECTOR.
 DOOR FRAME METAL DETECTOR.
 X-RAY BAGGAGE INSPECTION SYSTEM.
 EXPLOSIVE TRACE DETECTOR.

28. X- Ray Scanner:
BaggageX-

Organic
Inorganic
Metals
X -rays are used in x-ray baggage systems.
In this a baggage put in scanner ,then it
would show colour according to material.

29. EXPLOSIVE TRACE DETECTOR
 Narcotic/Explosive Detector is used to detect the
presence of any narcotics or explosive materials.

30. Conclusion
 Excellent opportunity to get to the Ground Level.
 It was an enriching experience.
 Co-operative and encouraging staff makes it a true
learning experience.
