• The Airports Authority of India (AAI) was formed on 1st April 1995 by merging the
International Airports Authority of India and the National Airports Authority with a
view to accelerate the integrated development, expansion and modernization of the
operational, terminal and cargo facilities at the airports in the country conforming
to international standards.
• AAI manages 126 airports, which include 11 international airports, 89 domestic
airports and 26 civil enclaves at Defense airfields
• AAI provides air navigation services over 2.8 million square nautical miles of

(usually microwave); part of a more
extensive telecommunication network.
Use frequency modulation technique.
It’s frequency at Jaipur Airport is 166.2MHz
A Base station called “challenger” is
provided for it.
Air traffic control (ATC)
• It is a service provided by ground-based controllers who direct aircraft on the ground and in the air.
• The primary purpose of ATC systems worldwide is to separate aircraft to prevent collisions, to organize
and expedite the flow of traffic, and to provide information and other support for pilots when able.
• In addition to its primary function, the ATC can provide additional services such as providing information
to pilots, weather and navigation information and NOTAMs (Notices to Airmen).
The DR100 multimode VHF receiver
• It is a state-of-the-art communication unit specifically designed to operate as radio core part of Air Traffic Control ground
• It is able to support a huge number of operating modes, ranging from the traditional AM-DSB mode for analogue speech
communications, to the latest VDL 3 and 4 modes* for voice and data or data-only links.
• Due to its DSP-based architecture, software-radio approach, and modular design, it allows for easy update and re-
configuration in terms of type of modulation, channel spacing and interface to external controllers.
• The equipment has outstanding performances in terms of noise radiation and unwanted emissions together with the high
grade of immunity to external interference.
• The equipment has been designed to fulfill operating requirements in any possible system layout. This results in an
extreme degree of flexibility and operability. It can also be used as direct replacement of analogue VHF equipment in
traditional ATC systems

• The Digital Voice Tape Recorder is used for audio recording.
• It can record 24 channels simultaneously.
• In this about 20 channels are fixed while remaining 4 channels can be set as requirement.
• Recording is done on magnetic tape and saved about 2 months.
Communication is the process of sending , receiving and processing of information by electrical
means. Basically communication system consist of 3 major blocks which are :
Crystal Osc. Modulator
Audio and Power
•Navigation is the ART of determining the position of an aircraft over earth’s surface and guiding it’s
process from one place to another.
•To accomplish this ART some sort of aids are required by the pilots, called the navigational aids.
•Radio Navigation is based on the use of Radio Transmitter, Radio Receiver and propagation of
electromagnetic waves to find navigational parameter such as direction, distance, position of the aircraft
• According to service range the radio navigational aids are broadly classified into three categories -
1. Long Range.
2. Medium Range.
3. Short range.
1. Long Range navigational aids
•Operate in very low frequency and low frequency, i.e. 10KHz, 50-100KHz and 100-200KHz respectively.
•Provide very long ranges of the order of 7000Kms and 700Kms.
•They are based on the hyperbolic system of navigation.
•LORAN and OMEGA falls in this category.
2. Medium range navigational aids
• It operates in the LF or MF band of frequency .
• It gives the range of 150-250 nautical miles.
• NDB (Non Directional Beacons) falls in this category.
3. Short-range navigational aids
• These aids operate in and above VHF bands.
• The coverage is dependent upon line of sight
• VHF, ILS, DME, VOR and RADAR are some widely
used short-range aids.

DISTANCE MEASURING EQUIPMENT(DME) :
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.
* It is a type of radio navigation system for aircraft. VORs
broadcast a VHF radio signal encoding both the identity of the
station and the angle to it, telling the pilot in what direction he
lies from the VOR station, referred to as the radial.
* It operates in the VHF band of 112-118 MHz, used as a medium
to short range Radio Navigational aid. It works on the principle
of phase comparison of two 30 Hz signals
* There are two types of VOR, namely, conventional VOR (C-VOR)
and Doppler VOR (D-VOR).

monitoring the behavior activities,
or other changing information.

◙ Radars are employed throughout the world for
the purpose of safely controlling air traffic en-
route and in the vicinity of airports.

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
DOOR FRAME METAL DETECTOR.

and audio aid.
X-RAY BAGGAGE INSPECTION SYSTEM
This system has a single X-ray source sending out X-
rays, typically in the range of 140 to 160 kilovolt peak
(KVP). KVP refers to the amount of penetration an X-
ray makes. The higher the KVP, the further the X-ray
After the X-rays pass through the item, they are
picked up by a detector. This detector then passes
the X-rays on to a filter, which blocks out the lower-
The remaining high-energy X-rays hit a second
detector. A computer circuit compares the pick-ups
of the two detectors to better represent low-energy
objects, such as most organic materials.

Narcotic/Explosive Detector is used to detect the presence of any narcotics
or explosive materials.
It works on the principle of Ion-Mobility Spectrography.
warm up period is 30 minutes.
