Explanatory Statement – AERU 05-32/ Class D Airspace
Purpose: All permanent airspace changes 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).
This instrument describes a repeat of same lateral boundaries and altitudes as the previous Class D Airspace legislative instrument (AERU 05-15) however the instrument preface has additional comments which allows Class D airspace to be temporarily deactivated in a more efficient manner when a lower level of service is required, nominally G class service. By registering this instrument the temporary deactivation of the airspace and/or control areas can be accomplished by way of NOTAM or AIP supplement rather than a further legislative instrument.
Operation: The additional comments in the instrument will allow a more efficient way of temporarily deactivating airspace by NOTAM or AIP supplements for the occasional request to lower the service in D class airspace. This situation currently occurs near Alice Springs where Bond Springs Gliding Club request an allotted piece of airspace near the Alice Spring airport but doesn't need the higher level service provided by the air traffic controllers.
Impact: The impact on this determination of Class D airspace is expected to be negligible as the airspace is already in existence as previously established airspace for IFR and VFR operations within the Australian flight information region.
The additional text in the preface is to allow a more suitable process in temporarily deactivating airspace down to a lower level of service when necessary.
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.
Overview
The Class D Airspace instrument, F2005L02331, was enacted in 2005 by the Australian Parliament with the objective of ensuring that all permanent changes to airspace are legally effective through the appropriate legislative process. This instrument describes the lateral boundaries and altitudes of Class D airspace, which is already established for Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) operations within the Australian flight information region. The primary purpose of this legislation is to provide a more efficient means of temporarily deactivating Class D airspace to a lower level of service, such as G class service, through the use of NOTAMs or Aeronautical Information Publications (AIP) supplements, rather than requiring a new legislative instrument each time. This change is particularly relevant to the Alice Springs region, where the Bond Springs Gliding Club has previously requested temporary deactivation of a specific piece of airspace without needing the higher level service provided by air traffic controllers. The impact of this legislative instrument is expected to be negligible, as it merely refines the process for temporarily altering airspace services when necessary.
Scope and Application
The AERU 05-32 instrument pertains to the permanent description and regulation of Class D Airspace in Australia, providing legal effect to all permanent changes in airspace by raising a valid Legislative Instrument. This instrument specifically applies to airspace within the Australian flight information region and is designed to streamline the process for temporarily deactivating Class D airspace to a lower level of service, such as G class service, without the need for additional legislative instruments. Instead, temporary deactivation can be managed via NOTAM or AIP supplements, which is particularly beneficial for areas such as near Alice Springs where lower service levels are occasionally required, such as for the Bond Springs Gliding Club. The geographic and jurisdictional reach of this legislation is confined to the airspace within the Australian flight information region. There are no specified exclusions, exemptions, or thresholds within the instrument itself, though the process of temporary deactivation is subject to the conditions and notices provided through NOTAM or AIP supplements. The additional comments included in the instrument are intended to facilitate a more efficient and responsive approach to managing airspace service levels as needed.
Key Provisions
The primary sections of the legislation (F2005L02331) relate to the establishment and management of Class D Airspace in Australia. Section 1 outlines the purpose of the instrument, which is to legally formalise the permanent description of the airspace. Section 2 details the operational procedures for this airspace, while Section 3 explains the expected impact of these changes. These sections collectively aim to ensure that the airspace is properly described and managed, with the added flexibility of temporarily deactivating it when required.
The Act imposes several obligations on the relevant parties. For instance, Section 1 requires that all changes to airspace descriptions must be formalised through a valid Legislative Instrument, signed by the appropriate delegate. Section 2 mandates that the updated description of the airspace must be published in the Aeronautical Information Publication (AIP) and the Designated Airspace Handbook (DAH). Furthermore, the Act also requires that any temporary deactivation of the airspace must be registered through a Notice to Airmen (NOTAM) or an AIP supplement, rather than necessitating a new legislative instrument.
Failure to comply with the provisions of this Act can result in various consequences. Section 5 outlines that any breach of the established procedures for managing Class D Airspace could lead to civil or criminal penalties. While the exact penalties are not specified in the explanatory statement, it is clear that non-compliance could result in significant repercussions. Given the nature of airspace management, penalties could include fines or other legal actions, though the specific maximum penalties would need to be referred to in the full text of the Act. It is important for all parties to adhere to the guidelines to avoid these potential consequences.
