Fait accompli - the standard CASA response to the majority of comments submitted in relation to the OAR Airspace Change Proposal for Broome and Karratha;
CASA Response
Airspace changes are required to be made in compliance with the principles contained within the Australian Airspace Policy Statement 2010. Whilst safety remains paramount the airspace access and efficiency need to be taken into account. The risk assessment at these locations indicate that the airspace model proposed provides adequate safety for the operations involved together with improved access to VFR aircraft whilst allowing ATC to operate efficiently. The Broadcast Area, a temporary measure pending improved surveillance capability, removes the unknown aircraft factor from the equation and the Class E transponder requirement provides an additional defence.
The airspace model conforms to all the requirements to contain the operation of Category D aircraft within the control zone. The surrounding airspace is also designed to capture RPT jet aircraft operations, including holding patterns
Airservices’ argument that their model of Tower services to 4,500 ft AMSL delivers the required efficiencies is supported in principle by CASA in this instance. The airspace classification should not change this situation.
Please refer Advisory CircularAC 2-5-1(0) and the AAPS 2010
And this is the template response with respect to the last few comments submitted;
CASA has accepted in principle Airservices’ airspace management model for the airspace, namely, that their model of Tower services to 4,500 ft AMSL delivers the required efficiencies.
Airservices’ will apply their SMS to the implementation process to identify and mitigate identified risks.
It`s all there in terms of ideological principle.
