The Angolan airspace:
Angolan airspace is structured into flight information regions:
- FIR (Flight Information Region): this space extends from the surface (SFC) to the FL245 included
- UIR (Upper Information Region): this space extends above FL245
Air traffic services are provided in the Angolan airspace , the management of which has been entrusted to Angola by ICAO and which includes:
- Luanda FIR (FNAN)
Air traffic services
There are 3 main services available in our controlled airspace::
- Flight Information Service
- Alerting Service
- Procedural Control Service
Flight Information Service:
A Flight Information Service (FIS) is a non-radar service provided, either separately or in conjunction with other services, for the purposes of supplying information useful for the safe and efficient conduct of flights. Under a FIS the following conditions apply: Provision of the service includes information about weather, changes of serviceability of facilities, conditions at aerodromes and any other information pertinent to safety.
- The controller may attempt to identify the flight for monitoring and co-ordinationpurposes only. Such identification does not imply that a radar service is being provided or that the controller will continuously monitor the flight.
- Pilots must be left in no doubt that they are not receiving a radar service.
- Controllers are not responsible for separating or sequencing aircraft.
An alerting service is provided to notify appropriate organisations regarding aircraft in need of search and rescue aid, and assist such organisations as required.
Procedural Control Service:
Procedural control is a method of providing air traffic control services without the use of radar. It is used in regions of the world, specifically sparsely-populated land areas and oceans, where radar coverage is either prohibitively expensive or is simply not feasible. It also may be used at very low-traffic airports, or at other airports at night when the traffic levels may not justify staffing the radar control positions, or as a back-up system in the case of radar failure.
