NATIONAL AIRSPACE SYSTEM (NAS) – STAGE ONE IMPLEMENTATION
This letter introduces you to the first stage of a phased implementation of airspace reform in Australia. The new US-based airspace architecture offers considerable improvement over the existing system, with its aims being simplicity, compliance with the International Civil Aviation Organization (ICAO) airspace classifications and allocation of ATC services according to assessed risk. This approach provides the oportunity to identify and achieve cost savings in the future. Stage One of NAS implementation introduces three of the characteristics that comprise the entire project. The first two of these are scheduled for Thursday 28 November 2002, while the third will be introduced on Thursday 26 December 2002. These are the first of a series of changes that will take place over the next 12-18 months. The safe, successful implementation of the NAS will depend on the professional commitment of you, the pilots of Australia. The enclosed educational material, which covers the first two characteristics, has been developed by CASA to support the AIP SUPs you would already have received. CASA will send you material to cover the third characteristic closer to its implementation date. The box below summarises the Stage One changes.
From Thursday 28 November 2002:
• Rather than call ATS and ask for an area QNH, use a QNH from a local station within 100NM if you can obtain it. The objective of this change is to reduce unnecessary communication on frequencies used to provide separation services to IFR aircraft. If there is a location in Class G airspace (other than a CTAF or MBZ) where you have been giving CTAF type calls on the area frequency, use 126.7. The objective of this change is to reduce unnecessary communication on frequencies used to provide separation services to IFR aircraft.
•
Over its life, the NAS project will introduce significant and positive reform of Australia’s airspace architecture. There are more changes in Stages Two and Three, currently scheduled for June and November, 2003. You will receive further educational material prior to the implementation of these stages, which will ensure you have the appropriate knowledge and skills to adapt safely and smoothly. In the meantime, more information on the project can be found on the NAS website at www.dotars.gov.au/airspacereform. Please check this site regularly as information is frequently being added and updated.
