INTRODUCTION
 The ATC is bracing up to meet growing demands of
aircrafts with more ATC officers and new radar
systems.
 The air traffic control(ATC) is the busiest in the country
handling over 250 or more movements.
 It regulates the large volume of air traffic and also
handles test and military flights with varied aircraft
speed.

WHAT IS AIR TRAFFIC CONTROL?
 Air traffic control(ATC) is a service provided by ground based controllers who direct
aircraft on the ground and in the air.
 The task of ensuring safe operations of commercial and private aircraft falls on Air Traffic
Controllers.
 The controllers coordinate the movements of thousands of aircraft, keep them at certain
distance, direct them during movements, around bad weather and ensure smooth flow
with minimal delays.

TYPES OF AIR TRAFFIC CONTROL
1.En-route Controllers
i. Terminal
a. High Level airspace.
b. Low Level airspace.
ii. En-route
a. High Level airspace
b.Low Level airspace
2.Airport Controllers
i.Ground control.
ii.Local or air control.
iii.Clearance Delivery

DIVISIONS OF AIR TRAFFIC CONTROL
SYSTEM
 Air Traffic Control System Command Center
(ATCSCC)
 Air Route Traffic Control Centers (ARTCC)
 Terminal Radar Approach Control(TRACON)
 Air Traffic Control Tower (ATCT)
 Flight Service Station(FSS)

7.
AIRPORT CONTROL
 The primary method of controlling the airport enviro-ment is visual observation from the
control which is a tall, windowed structure at the airport.
 Tower controllers are responsible for the separation and efficient movement of aircraft and
vehicles operating on the taxiways of the airport.
 Controllers may use a radar display system called Secondary Surveillance or Airport
Surveillance Radar for airborne traffic approaching and departing.

DISCIPLINES OF AIRPORT CONTROL
 Ground control: It is responsible for the airport maneuvering
areas or areas not released to the airlines or other users.
 Local or Air control: It is responsible for the active runway
surfaces.
 Clearance Delivery: It is responsible for ensuring that the
aircraft has the proper route and slot time.
 Apron control: It exists at extremely busy airports

RADAR
RADAR CONTROL
FACILITIES(TRACON)
 Centers use long range radar to
control a large space area.
 Centers may use TRACON radar
data to control to provide better
picture of the traffic.
RADAR COVERAGE

11.
EN-ROUTE,CENTER OR AREA CONTROL
 En-route air traffic controllers work in facilities called Area Control Centers.
 Centers control IFR aircraft from the time they depart an airport or terminal area’s
airspace to the time they arrive at another airport.
 Centers may also pick up VFR aircraft that are already airborne and integrate them into
IFR system.

12.
CALL SIGNS
 Call signs are a used to safe air traffic separations and is used for scheduled flights and air
forces for military flights. Different types of call signs:
 ICAO call signs are written with 3-letter combination followed by the flight no.
 Audio or Radio-telephony call signs are used as the contact between pilots and Air Traffic
Control.

13.
TECHNOLOGIES IN AIR TRAFFIC CONTROL
 Conflict Alert (CA)
 Minimum safe altitude warning
 System coordination
 Area Penetration Warning (APW)
 Mode S

14.
PROBLEMS OF AIR TRAFFIC CONTROL
 Traffic
 Accidents
 Weather conditions

15.
SOLUTIONS
 New area control centre at Swan wick
 Modern software developed by FAA
and NASA

CONCLUSION
 The Air Traffic Control(ATC) is the third busiest in the country handling over 250 movements
(landing and takeoff) everyday.
 Besides regulating the large volume of air traffic, handling test and military flights with varied aircraft
speed.
 The ATC is, bracing up to meet the growing demands of an ever-increasing fleet of commercial,
civil and military aircraft- more air traffic control officers and new radar systems.
