Response text:

Airservices Australia advised that a Manual of Air Traffic Services (MATS)/Aeronautical Information Publication (AIP) request for change (RFC) had been issued 2 December 2006. The rules in MATS regarding visual separation can be misinterpreted and in some circumstances separation is not assured. The intention of the RFC is to:

  • clarify the application of visual separation and specifically the use of projected flight paths
  • restructure the visual separation rules to differentiate visual separation by the pilot and the controller
  • clarify when traffic information needs to be passed
  • include the use of surveillance systems in identifying aircraft prior to the application of visual separation.

The proposed changes were included in the MATS on 15 March 2007.
