This document provides information on the services provided by the Airports Authority of India (AAI). It describes the different types of air traffic control (ATC) services including approach control, area control, and flight information services. It also outlines some of the key communication, navigation, and surveillance systems used at airports, such as VHF radios, Doppler Very High Frequency Omni Radio Range (DVOR), Distance Measuring Equipment (DME), Instrument Landing System (ILS), Primary Radar, and Secondary Radar. In addition, it discusses security screening equipment like Door Frame Metal Detectors (DFMD), Hand Held Metal Detectors (HHMD), X-ray baggage screening, Closed-Circuit Television (CCT

10. Approach Control:
Responsible for providing all ATC services within their
airspace .
 Area Control :
provides services to aircraft between airports.

11. To describe airspace with specific dimensions, in which a
Flight Information Service and an alerting service are
provided.

14. 3.Air to air : This includes communication between the pilots of two
aircrafts in the air. Such type of communication also uses VHF and HF
frequencies.
For communication, A frequency band from 118MHz to 136 MHz is
used .

17. DVOR:
It is the Doppler Very High Frequency
Omni Radio Range which measures the
azimuth angle with respect to the north.
DME :
Provides pilots with a slant
range measurement of
distance to the runway in nautical
miles.

18.  Provides precision guidance to an aircraft
approaching and landing on a runway, using a
combination of radio signals.
ILS
GLIDE PATH
(GP)
LOCALIZER

19.  Provides runway centerline guidance to
aircraft, but not the glide slope information.

22.  An antenna array is sited to one side of the runway
touchdown zone.
 LOC carrier frequencies range
108.10 MHz to 111.95 MHz.
At Jaipur Airport it is 109.9 MHZ.
 The glide slope transmits
no identification signal.

23.  It is installed in each airport to monitor
the movement of all the aircrafts within its
region of operation.
•Range : 2700 to 2900 MHz .

24. Primary Radar :
• The radar system measures the time required for a radar
echo to return and the direction of the signal.
Range : 2700 to 2900 MHz .
•
 Secondary Radar :
•It 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.

26. 1.DFMD:
 Every passenger has to go through this frame when any metal
particle is possessed by passenger.
It gives indication with both visual &
audio aid.
2.HHMD:

27. X-Ray is used in x-Ray baggage systems .
In this a baggage put in scanner , then it would show color
according to material.
Baggage

28. CCTV is the use of video
cameras to transmit a signal to a
specific place, on a limited set of
monitors.
ETD is used to detect
explosive materials.
