Controlled Airspace


Controlled Airspace is an airspace of defined dimensions within which air traffic control service is provided in accordance with the airspace classification.

 

 

Services


There are 3 services available in controlled airspace

  • Flight Information Service
  • Alerting Service
  • Radar Control Service

 

 

Flight Information Service


  • The controller may attempt to identify the flight for monitoring and co-ordination purposes 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.

 

 

Alerting Service


An alerting service is provided to notify appropriate organisations regarding aircraft in need of search and rescue aid, and assist such organisations as required.

 

 

Radar Control Service


  • Radar control service may be provided to aircraft operating IFR, SVFR or VFR. When providing the service controllers issue instructions to which:
    • Pilots of aircraft operating IFR are required to comply; and
    • Pilots of aircraft operating SVFR or VFR will comply unless they advise the controller otherwise.
