6. What is CNS?
Communication, Navigation and Surveillance are three main functions
which constitute the foundation of Air Traffic Management infrastructure.
• Communication: Communication is the exchange of voice and data
information between the pilot and air traffic controller of flight information
centre's.
• Navigation: Navigation element of CNS/ATM system is meant to provide
accurate reliable and seamless position determination capability to aircrafts.
• Surveillance: The act of watching or monitoring the behavior activities, or
other changing information.

8. METAL DETECTOR
• Hand Held metal detector:
It is used to find the particular part of the body
at which any metal or other related particle is
there. It operates with chargeable battery
system.
• Door Frame metal detector:
Every passengers has to go through this frame
when any metal particle is possessed by
passengers. It gives indication with both visual
and audio aid.

9. X-BIS
• 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
•Inorganic
•Organic
•Metals
•Explosive
X-RAY

10. Cctv & Etd
• CCTV is the use of video cameras to transmit a
signal to a specific place, on a limited set of
monitors.
Two types of cctv are used:
1. Fixed Camera
2. Ptz Camera
• ETD is used to detect explosive materials.

11. ATC Tower
• The air traffic controllers are able to
direct control with the pilot and guide
them to move forward towards their
Destination.

12. VHF Communication
• Commumnication Is Done Through VHF.
• The Range Of Vhf Is 30mhz To 300 Mhz.
• It Is A Type Of Line Of Sight Communication.
• Modulation Technique Used Is Amplitude Modulation.
2 Type Of Antennas Are Used :
1. Directive Antenna 2. Omni-directional Antenna

14. Automatic Message Switching System
(AMSS)
The AMSS is a computer based system, centred on the AFTN for exchange of
Aeronautical messages by means of auto switching for distribution of messages
to its destination(s), which works on store and forward principle.

15. ILS
• The Instrument Landing System (ILS) provides a means for safe landing of
aircraft at airports under conditions of limited visibility.
• The ILS also increases the traffic handling capacity of the airport under all
weather conditions.
• 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.
Components of ILS:
1. Localizer
2. DVOR
3. DME

16. Localiser & DVOR
• Localiser:
Provides runway centerline guidance to
aircraft, but not the glide slope
information.
• DVOR:
It is the Doppler Very High Frequency
Omni Radio Range which measures the
azimuth angle with respect to the north.
16
17. DME
• DME(distance Measuring Equipment) :
Term combining Ground Based and
Airborne Equipment to measure the
distance of the aircraft from a ground
station.
• Provides slant distance of the aircraft
from the ground equipment/station
