Member of International Federation of Air Traffic Controllers' Associations


Air Traffic Controllers' Association of Sri Lanka (SLATCA) was inaugurated in 1949 with the objective of addressing the professional, technical, social and legal issues of all the Air Traffic Controllers in Sri Lanka. SLATCA was later affiliated to the international body, International Federation of Air Traffic Controllers' Associations (IFATCA) in 1975.

SLATCA is a professional Association registered under 206. The council of committee comprises 10 members who are only Air Traffic Controllers. They are selected through an election and hold office for a period of 1 year. Also there are sub committees, headed by a council member, supporting the council in technical, professional and legal aspects of the controllers. SLATCA also assists the Air Navigation Service Provider in Sri Lanka, Airport & Aviation Services Sri Lanka Limited (AASL) in numerous ways in matters relating to Air Navigation Services.

SLATCA in the past played a Vital role in the privatization process of the organization in 1982, which enabled better facilities for the staff including better salaries. SLATCA effectively addressed the salary issues of the Controllers continuously and in was able to reach regional standards in 2004. This enabled to prevent brain drain and to recruit quality trainees for the profession.




Air traffic control (ATC) 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.

Preventing collisions is referred to as separation, which is a term used to prevent aircraft from coming too close to each other by use of lateral, vertical and longitudinal separation minima; many aircraft now have collision avoidance systems installed to aircraftt as a backup to ATC observation and instructions. In addition to its primary function, the ATC can provide additional services such as providing information to pilots, weather and navigation information and NOTAMs

ATC services are provided throughout the majority of the airspace, and its services are available to all users (private, military, and commercial). When controllers are responsible for separating some or all aircraft, such airspace is called "controlled airspace" in contrast to "uncontrolled airspace" where aircraft may fly without the use of the air traffic control system. Depending on the type of flight and the class of airspace, ATC may issue instructions that pilots are required to follow, or merely flight information (in some countries known as advisories) to assist pilots operating in the airspace. In all cases, however, the pilot in command has final responsibility for the safety of the flight, and may deviate from ATC instructions in an emergencies.



Air Traffic Controllers are generally individuals with excellent spatial awareness, are numerate, calm under pressure and able to follow and apply rules yet be flexible when necessary. Normally trainee controllers begin work in their twenties. Rigid physical and psychological tests and excellent vision, hearing, speaking skills are a requirement, and controllers must take precautions to remain healthy and avoid certain medications that are banned for controllers.

Most training focuses on improving the ability to absorb data quickly from a variety of sources, and to use this to visualize, in time and space, the position of each aircraft under control, and to project this forward into the near future. This skill is termed situational awareness (having the picture or having the flick), and is central to the job. This is then used to make relatively simple rule-based decisions very quickly and accurately to keep aircraft separated in the sky while moving traffic as expeditiously as possible and presenting the traffic in an orderly and useful manner to the next sector.

Communication is a vital part of the job: controllers usually communicate with the pilots of aircraft using a simple radiotelephony system, which has many attendant issues. Although other languages are sometimes used, the default language of aviation is English and controllers who do not speak this as a first language are generally expected to show a certain minimum level of competency with the language.

Teamwork plays a major role in a controllers job, not only with other controllers and air traffic staff, but with pilots, engineers, managers Technical personal etc.

Work in the glassed-in towers you see at airports. They manage traffic from the airport to a radius up to 10 Nautical miles out. They give pilots start-up,taxiing and take off instructions, Air traffic clearance, and advice based on their own observations and experience. They provide separation between landing and departing aircraft, transfer the control of aircraft to Approach control center controllers when the aircraft leave their airspace, and receive control of aircraft coming into their airspace. Surface movements also controlled by the Aerodrome Control Tower

Terminal Approach Radar Center

Work in Radar rooms, Approach controllers are responsible for the safe separation and movement of aircraft departing, landing, and maneuvering in the airport environment. They normally control traffic below 15,000 feet and up to radius of 60 Nautical miles. Approach controller act as an inter-mediator between Area control and Tower

Area Control Center

Work in a location away from our International airport, located at Ratmalana. You will never see them during the course of your flight, but they will normally direct your aircraft for the bulk of your ride. They usually control traffic at or above 15,000 feet. These controllers give aircraft instructions, air traffic clearances, and advice regarding flight conditions during the en route portions of flights.The area controllers use radar or procedural control to keep track of the hundreds of planes in the sky at any one time. This typical center has responsibility for more than 604800 SqNm2of airspace
