Aviation safety issues and actions
Interim Recommendation issued to: AirServices Australia
|Date issued:||24 March 1998|
|Safety action status:|
Safety Interim Recommendation
The Bureau of Air Safety Investigation recommends that Airservices Australia review the guidance in the MATS for the passing of traffic information by ATS personnel to ensure pilots have adequate time to assess the potential for conflict with other aircraft.
|Date issued:||17 November 1998|
|Response from:||AirServices Australia|
Airservices has revised the methodology and parameters for passing traffic information in its "proposal to amend G Airspace procedures- originally planned for introduction on 16 July 1998.
This procedure amendment has been deferred until later in 1998 to facilitate further consultation and development.
The following letter was sent to Airservices Australia on 6 December 1999:
Subject: Outstanding airspace related safety actions
Responses to some previous safety recommendation to Airservices Australia and the Civil Aviation Safety Authority (CASA) proposed actions that were subject to the latter's Airspace 2000 initiative or the resolution of related issues.
Since the Minister of Transport and Regional Services' statement clarifying the roles and responsibilities for airspace management it has become apparent that, with the change in roles, CASA may not be in a position to implement all of their proposed airspace related safety actions. Consequently, there is the likelihood that there will be less safety enhancement of airspace than there previously might have been.
However, should Airservices Australia review the safety
recommendations previously forwarded to CASA and the subsequent
responses, during the development of the new airspace project, the
knowledge gained from past air safety investigations has the
potential to be retained. Consequently,
Similarly, advice of any proposed action in regard to IR19960009, IR19980005 and IR19980059 issued to Airservices, where further action was also subject to CASA's Airspace 2000, would assist the ATSB in understanding the integration of safety lessons with future airspace developments.

|Response from:||AirServices Australia|
|Response status:||Closed - Partially Accepted|
I apologise for the late response to your letter dated the 6th of December 1999, concerning the resolution of matters relating to the Airspace 2000 initiative. We note the recent statement by the Minister for Transport and Regional Services, and its effect in clarifying the roles and responsibilities for airspace management.
In the current airspace management arrangements, Airservices holds the legislative responsibility for the declaration of airspace in accordance with the ICAO "alphabet" menu of airspace. Responsibility for procedures applicable within airspace classes, including Class G airspace, together with ongoing training and pilot education remains with the Civil Aviation Safety Authority.
In that context, we believe that Recommendation IR19970155, relating to separation assurance in Class G airspace is more properly directed to CASA.
In relation to Recommendations IR19960009, IR19980005 and IR19980059, I offer the following advice.
IR19980005: Whilst Airservices disagrees in part with the investigation report, the recommendation is accepted.
Several initiatives have been undertaken to ensure that traffic information is facilitated to aircraft leaving controlled airspace for Class G airspace. For example, the Manual of Air Traffic services was amended in 1998 to require air traffic controllers to provide radar based traffic information to aircraft operating within 2000 feet of the base of controlled airspace.
The transitioning of low level Class G airspace services into TAAATS through 2000 will also significantly enhance the level of service provided to aircraft operating in, or transiting to Class G airspace. This will ensure not only the timely passing of traffic information, but through the utilisation of TAAATS capabilities, the passing of more relevant information than was previously available through Flight Service.
In relation to your statement regarding the integration of safety lessons with future airspace developments, Airservices is acutely aware of the primacy of safety in all aspects of our operations. In work being undertaken with industry to achieve reforms in the provision of services in low level airspace, detailed examination of hazards, potential mitigations, safety analysis and risk modelling are a fundamental part of our considerations. We would welcome the opportunity to provide you and your staff with a briefing on that reform program at your convenience.
