BIA Control Tower controls all aircraft departing from & arriving to BIA on ground from the Aircraft parking Stand to its Take-off from runway and vice versa after landing on Runway, on air between ground and 4000 feet within a radius of 10 nm from BIA. It not only provides separation to aircraft from one another and/or from terrain, but also vital information viz. local and en-route weather, hazardous information (if any) and alerting service if/when in distress.

Approach Radar Control Center takes-over traffic departing BIA and/or Ratmalana Airports passing 4000 feet or 10 nm or even earlier in order to provide more efficient and expeditious Air Traffic Control Service using Mono-pulse Secondary Surveillance Radar (MSSR) equipment installed at BIA and hands them over to Colombo Area Control Centre when passing 15000 feet or reaching 60 nm from BIA.

Conversely the arriving aircraft are taken-over from Colombo Area Control Centre when passing 15000 feet or reaching 60 nm from BIA and handed-over to BIA or Ratmalana Control tower within the vicinity of the airport or in most instances on Final Approach to Land. All aircraft transiting the area of 60 nm of Katunayake below 15000 ft are also provided with Air Traffic Control Service. In addition to providing safety to all these aircraft an overall air surveillance across the Radar Coverage is also within its purview whilst Radar Flight Information Service and Alerting Service are also provided where appropriate.

Ratmalana Control Tower controls all aircraft departing from & arriving to Ratmalana on ground from the Aircraft parking Stand to its Take-off from runway and vice versa after landing on Runway, on air between ground and 4000 feet within a radius of 10 nm from Ratmalana. It not only provides separation to aircraft from one another and/or from terrain, but also vital information viz. local and en-route weather, hazardous information (if any) and alerting service if/when in distress.

Area Control Centre (ACC) takes-over departing air traffic from Approach Radar Control Centre in order to provide separation between aircraft before handing them-over to the adjacent Area Control Centres in Chennai or Trivandrum in India, Male` in the Maldives, Jakarta in Indonesia or Melbourne in Australia. Conversely all arriving air traffic taken-over from the above adjacent ACCs are handed-over to Approach Radar Control Centre when they are within 60 nm of Katunayake approaching 15000 feet descending to approach and land at BIA. Two (02) Sectors have been identified within ACC , namely Terminal Control Area (TMA) and Oceanic Control (OCP) to control aircraft flying over land and ocean respectively.

Flight Information Service (FIC) is co-located with the ACC in order to provide Flight Information Service to all flights within Sri Lankan airspace / Colombo Flight Information Region (FIR). It constantly coordinates with all adjacent FICs in order to provide an uninterrupted service to all flights.

Rescue Coordination Centre (RCC) is also co-located with the ACC and activated whenever a necessity arises for the Search and Rescue Service mission in or around Sri Lankan Airspace / Colombo FIR. SAR Activities are coordinated with local agencies as well as international organizations in order to endeavor successful rescue missions in respect of aircraft and/or vessels within the region.
