Responsibilities of area control

Air traffic controllers at area control centres provide en-route aircraft with instructions, air traffic clearances and advice regarding flight conditions. They provide separation between aircraft flying along established ATS routes.

Area controllers use radar or in some cases manual procedures to track the progress of all instrument flights within the centre’s airspace. Area controllers also provide radar service to pilots who are not on instrument flight plans, alerting them to potential traffic conflicts. Area controllers transfer control of aircraft to controllers in other facilities, when aircraft enters that facility’s airspace.
