Background: Why this Recommendation was developed

Output text

The Civil Aviation Safety Authority, in conjunction with Airservices Australia, review the existing airspace model with a view to enhancing conflict recognition and resolution for fare-paying passenger operations to/from non-controlled aerodromes.

Initial response
Date issued: 22 June 2001
Response from: Civil Aviation Safety Authority
Action status: Closed - Accepted
Response text:

Although no response was received from CASA, the following response was received from Airservices Australia and is considered to represent both agencies:

Airservices Australia accepts the recommendation although, as detailed below, current circumstances are vastly different from that experienced at the time of this incident.

The process to address the recommendation is already well under way, and the airspace model that was in use when this incident occurred no longer exists.

When the incident occurred, Flight Service provided Directed Traffic Information. Airservices Australia now provides all traffic information services in low level airspace from the Enroute TAAATS centres. This has enhanced safety by providing pilots with radar advisory services (where radar coverage exists) as a part of normal services.

Airservices Australia is working with Industry and CASA to finalise the Low Level Airspace Management Plan (LAMP). LAMP is designed to provide a higher level of service to fare paying passenger operations by increasing the amount of Class E airspace (controlled) throughout Australia, and to simplify frequency management and broadcast procedures in Class G airspace.

Improved frequency management will be achieved by ensuring that terminal operations below controlled airspace are managed on a single frequency, thereby reducing the possibility of missed communications between pilots. Simplified frequency management in Class G airspace enhances the ability to manage radio alerted traffic information broadcasts between pilots.
