BOUT IRPORT UTHORITY OF INDI

Airports Authority of India (AAI) was build by anAct of Parliament and came into being on 1st April,1995 by merging erstwhile National AirportsAuthority and International Airports Authorityof India.

AAI manages 126 airports, which include 11international airports, 89domestic airports and 26 civilenclaves at Defence airfields

CommunicationSystem

Communication is the process of sending , receiving and processing of information byelectrical means. Basically communication system consist of 3 major blocks which are :

Transmitter

Channel

Receiver

Audio Amp.

'ART' of determining the position of an aircraft overearth's surface and guiding its progress from one placeto another

Nav-Aids used by AAI:

NDB VOR DME ILS Sat.Nav.

N V IDS

I.L.S. (Instrument Landing System)

Localizer : Helps aircraft to identify the

central line of runway.Range:- 10-25 NMFrequency:- 108-111.9 MHz

Glide Path : Gives the glide angle i.e. angleof declination achieve for safe landing.

Range:- 10 NM(-8 to +8degrees)

Safe glide angle:- 2-4 degrees


10/18

DISTANCE MEASURING EQUIPMENT(DME) :

DME is used in navigational aid which provide apilot with visual info regarding hisposition(distance) related to ground base DMEstation.

The frequency range used for DME is between960 MHz to1215 MHz .


11/18

RADARis stand for RadioDetectionAndRanging and was developed prior to WorldWar II.

It is used by ATCto monitor and controlnumbers of aircrafts in airspace as well as bypilotforweather warning and navigation.


12/18

Radar operates on UHF and SHF - Super HighFrequency (1 GHz - 30 GHz).

RADAR systems are in SHF bands because:

a) These frequencies are free from disturbance.

b) Higher frequency, shorter wavelength, RADARmore effective.(shorter wavelengths are

reflected more efficiently.)

Toprovide aerodrome control service.

To direct pilots to the runway, taxiway, or apron,issue instructions for takeoff and landing,

To control the flow of runway traffic so that it ismost efficient and safe (fast clearance, no hold ordelay)


15/18

To updateimportant information suchweather.

ATC also responsible for checking weather statistics

at both the current airport and future destination toensure the safest route of travel and issue anypossible weather delays.

Have to contact Meteorological Stations (METs) to

update the weather info.


16/18

ATC are alsovital in the case of an emergency.

Should an airplane encounter problems, the airtraffic controllers role is extremely important.

The air traffic controllers will maintain contact withthe pilots, aid in overcoming any flight problems,provide flight path changes for bad weather and inextreme circumstances, direct pilots to a specific areafor emergency landings.

As example, aircraft crash, bomb threat, hi-jacking,etc.


17/18

It was a great experience at Airport Authority of India,Udaipur. During our training period we got an

opportunity to see many of the equipments like theHHMD, DME,ILS,DFMD SYSTEM etc.
