Explanatory Statement –Class D Control Zones
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.
The attachment to this instrument is a duplicate of the section of the DAH, which becomes effective 23 November 2006, describing the Class D Control Zones.
Operation: The Class D Control Zones legislative instrument describes the area which has been determined as necessary to contain the paths of IFR flights arriving and departing from aerodromes to be used under instrument metrological conditions.
Impact: The impact on the determination of Class D Control Zones is expected to be negligible. These zones are established for current IFR and VFR operations within the Australian flight information region and there are no new additions in this DAH issue.
The Office of Regulation Review determined this instrument appeared unlikely to have direct or significant indirect impact on businesses and therefore confirmed a Regulation Impact Statement would not be required.
