Explanatory Statement – Temporary Reclassification of Class G Airspace
Purpose: All changes to airspace are given legal effect by the raising of a valid Legislative Instrument, signed by the appropriate delegate. The permanent description of airspace is published in the AIP MAP products (as defined in ICAO Annex 15) and in the Designated Airspace Handbook (DAH). The DAH is issued on an alternating approximate 24/28 week cycle. The DAH lists and describes, in tabular form, the lateral and vertical limits and any other pertinent details of airspace volume.
When there is a temporary change to the airspace described in the DAH, this is promulgated by a Notice to Airmen (NOTAM). This instrument gives legal effect to that NOTAM.
Operation: In this case a very small portion of airspace is being reclassified to allow gliders to utilise airspace for a national event near Gawler, South Australia. Air traffic services in the reclassified airspace will be appropriate for Class G.
Impact: The impact of this reclassification is minor and of a temporary nature and therefore does not require a RIS.
