Air Traffic Services objectives

- Prevent collisions between aircraft
- Expedite and maintain an orderly flow of air traffic
- Provide advice and information useful for the safe and efficient conduct of flights
- Notify appropriate organisations regarding aircraft in need of search and rescue and rescue aid, and assist such organisations as required

ATS provides three services

1. Air Traffic Control Service
2. Flight Information Service
3. Alerting Service

Air Traffic Control (ATC) Units

- Area Control Centres (ACC)
- Approach Control Offices (APP)
- Aerodrome Control Towers (TWR)
They provide air traffic control service, flight information service and alerting service within control areas, control zones and at controlled aerodromes
