Background: Why this Recommendation was developed

Output text

The Australian Transport Safety Bureau recommends that Airservices Australia review the design of STARS and Instrument approaches with a view to improving separation assurance during communications or radar failure.

Initial response
Date issued: 25 May 2001
Response from: AirServices Australia
Action status: Monitor
Response text:

Strategic separation assurance is built into Airservices' procedures (eg. SID/STAR arrangement) and these procedures are generally applicable within 20NM of Sydney Airport. From that point tactical separation, including where practicable, separation assurance is applied as necessary. Application of a more rigid strategic separation assurance methodology within the 20NM radius would adversely affect traffic management flexibility and capacity.

Airservices has reviewed current procedures and as a result considers that the current arrangements provide sufficient defence in the event of communications or radar failure. In the incident that is the subject of this report, separation was maintained throughout.

Airservices is conducting a further review of existing procedures to ensure consistency of application and publication.
