3.  An organization working under the ministry of civil
aviation that manages all airports.
 Formed on 1st April 1995 by merging the
international airport authority & national authority.
The AAI manages and operates total 125 airports
including 11 international , 89 domestic & 25 civil
enclaves.

4. To provide uninterrupted services of Communication,
Navigation and Surveillance (CNS) facilities for the
smooth and safe movement of aircraft (over flying,
departing & landing) in accordance with ICAO
standards and recommended practices.

COMMUNICATION
It stands for

6. 6
It has three types :-
Air to air
Air to ground
Ground to ground

7. This includes communication between the pilots
of two aircrafts in the air. Such type of
communication also uses VHF(30MHz-300MHz)
and HF(3MHz-30MHz)
7

8. AIR TO GROUND:-
Air to ground network provide a linkage
between aircraft based and ground based routers via satellite
and other modes.
In this communication VHF (30 MHz-
300MHz) frequency band is used.
GROUND TO GROUND:-
It is formed by the Aeronautical Fixed
telecommunication network (AFTN),automatic message
switching system(AMSS)

9. The basic principle of air navigation is the process
of planning, recording and controlling the movement of
a craft from one place to another.

SYSTEM OF NAVIGATION
V.O.R. System :-
VHF Omni directional Range
antenna
Freq. band : 108 -118 MHz
Power : 100W
Polarization : Horizontal
Range : 200Nm
 Antenna : alford loop
V.O.R system provides, pilot the position of aircraft w.r.t north
direction from V.O.R station.

11. 11
D.M.E. :-
Distance Measurement Equipment
Distance Measuring Equipment is
a vital navigational Aid, which provides a pilot with visual
information regarding his position (distance) relative to the ground
based DME station.
Normally it is collocated with either VOR or ILS.
Freq. range: 960MHz -1215MHz
Polarization: vertical
Range: 200Nm
Power : 100W

INSTRUMENT LANDING SYSTEM (ILS)
The function of an ILS is to provide the
PILOT or AUTOPILOT of a landing aircraft with the guidance to and
along the surface of the runway. This guidance must be of very high
integrity to ensure that each landing has a very high probability of
success.
Mainly, ILS has two type of systems :-
LOCALIZER
GLIDE PATH ANTENNA

14. 14
LOCALIZER
Freq. band: 108-112MHz
Range: 15Nm
 Provides runway centerline guidance to aircraft, but not
the glide slope information.

15. 15
GLIDE PATH ANTENNA
Range: 10Nm
Freq. band: 328-336MHz
It provides a plane align with the glide path of runway for providing
elevation guidance to landing aircraft.

AIRPORT SURVEILLANCE RADAR
An Airport Surveillance Radar(ASR) is a radar
system used at airports to detect and display the position of aircraft
in the terminal area.
 This system monitors the movement of all the aircrafts within
its region of operation.
 ASR includes primary
surveillance radar and secondary
surveillance radar.

18. 18
PRIMARY SURVEILLANCE RADAR:-
The primary surveillance radar
uses a continually rotating antenna mounted on a tower to transmit
electromagnetic waves that reflect from the surface of aircraft up to
60 miles from the radar. The radar system measures the time
required for radar to echo to return and the direction of the signal.
From this, the system can then measure the distance of the aircraft
from the radar antenna and the azimuth, or direction, of the aircraft
in relation to the antenna.
Freq. Range : 2700 to 2900 MHz.
Power range about 25kw

19. 19
SECONDARY SURVEILLANCE RADAR:-
The secondary radar uses a second radar antenna attached to the
top of the primary radar antenna to transmit and receive area aircraft
data for barometric altitude, identification code, and emergency
conditions.
Freq. Range : 1030 to 1090 MHz
power ranges : 160 to 1500 watts.

SECUIRITY EQUIPMENTS
Metal detectors
X-ray scanners
Chemical sniffers
Dog sniffers
•Hand held metal detector
•Dore frame metal detector

21. 21
HAND HELD METAL DETECTOR
It detects all metals ,both ferrous and non-ferrous.
A metal detector is an electronic instrument which
detects the presence of metal nearby.

22. 22
DOOR FRAME METAL DETECTOR
Door Frame Metal Detector walk-through metal detector which uses
advanced magnetic technology to accurately pinpoint the location,
size and number of hidden weapons, such as knives and guns.

23. 23
X-RAY SCANNERS
It detects three types of materials:-
MATERIAL TYPE COLOR ON MONITOR
Organic Orange
Inorganic Greeen
Metal Blue
In this a baggage put in
scanner , then it would show
color according to material.

24. 24
CHEMICAL SNIFFERS
It is a security device that seeks to detect explosives and illegal drugs
at airports and other sensitive facilities as a part of airport security
screening.
This system collects the chemical
molecules from the handle of bag
of outer surface of bag.

25. 25
SNIFFERS DOG
A detection dog or sniffer dog is a dog that is trained and works
at using its senses (almost always the sense of smell) to detect
substances such as explosives, illegal drugs, blood.

CONCLUSION
In this fast moving world the airports are playing an important part in
the field of transportation. Airports are required to take care of
passengers, their luggage and other amenities as well the security of the
passengers as well of itself.
Airport management department has to play significant role in smooth
and effective functioning of terminal operation.
Airport Management discipline can be made responsible to carry out
this task in coordination with other concerned department of AAI.
