The department is responsible for the provision of a safe, effective and efficient air navigation service within the Seychelles Flight Information Region (FIR). This flight information region covers an area of approximately 2.63 million square kilometers and borders the flight information regions of Kenya, Somalia, India, Mauritius, Madagascar and Tanzania. The department encompasses the Air Traffic Management and Communication Navigation Surveillance divisions.
Air Traffic Management (ATM)
The ATM Division comprises of the following sections: Air Traffic Services (ATS) Responsible for the provision of air traffic control service, flight information service and alerting service to aircraft operating within the Seychelles FIR. The services are provided by competent air traffic Controllers who are trained and licensed in accordance with regulations derived from international standards. These Controllers manage a total of four ATS units described below:
- En-route Oceanic Control Centre: Responsible for the provision of area control service to aircraft operating on ATS routes in the Seychelles flight information region excluding the terminal control area.
- Approach Control Unit: Responsible for the provision of approach control service to aircraft arriving to and departing from Seychelles International Airport (SIA) excluding the Mahe and Praslin Towers Control Zones. This Unit is also responsible to provide air traffic control service to all flights over flying and operating at other aerodromes within the Control Area (CTA).
- Mahé Control Tower: Responsible for the provision of aerodrome control service to aircraft operating in and out of SIA and aircraft operating in the SIA Control Zone (CTR).
- Praslin Control Tower: Responsible for the provision of aerodrome control service to aircraft operating in and out of Praslin aerodrome and aircraft operating in the Praslin Control Zone (CTR).
Aeronautical Information Service (AIS)
