Explanatory Statement – AERU 05-30/ Class C 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 C Airspace legislative instrument (AERU 05-13) however the instrument preface has additional comments which allows Class C 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 C 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 C 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 C Airspace instrument, F2005L02323, was enacted to provide legal effect to permanent airspace changes, ensuring they are documented and accessible through the Aeronautical Information Publication (AIP) and the Designated Airspace Handbook (DAH). This instrument replicates the lateral boundaries and altitudes of its predecessor, AERU 05-13, but includes additional commentary that facilitates the temporary deactivation of Class C airspace to a lower level of service, such as G class service, through means like Notices to Airmen (NOTAM) or AIP supplements rather than requiring a new legislative instrument each time. Enacted by the appropriate delegate, this legislation aims to streamline the process of altering airspace services, particularly in response to requests from entities like the Bond Springs Gliding Club near Alice Springs, thereby improving operational efficiency and reducing administrative burden. The minimal impact on existing airspace operations and the Office of Regulation Review's assessment that it is unlikely to have a significant effect on businesses underscore its practical approach to airspace management.
Scope and Application
The AERU 05-30/ Class C Airspace instrument pertains to the legal establishment of permanent airspace modifications within Australia, providing a statutory foundation for these changes, as mandated by the legislative framework. This Act applies to the defined airspace, ensuring that any alterations to the lateral boundaries and altitudes of Class C airspace are formalised through the issuance of a valid Legislative Instrument, which is signed by the appropriate delegate. This legal framework is crucial for maintaining the integrity and safety of the Australian flight information region, where the airspace is already operational for both Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) operations. The Act’s jurisdiction covers the entire Commonwealth of Australia, ensuring a uniform approach to airspace management across the nation. Additionally, the instrument introduces procedural efficiency by allowing temporary deactivation of Class C airspace to a lower level of service, such as G class, via NOTAMs or AIP supplements, instead of necessitating another legislative instrument. This change is particularly beneficial near Alice Springs, where the Bond Springs Gliding Club requires access to a specific airspace segment without the higher level of service provided by air traffic controllers. The impact of this legislation is considered negligible, as it primarily facilitates a more streamlined process for temporarily adjusting airspace services when required.
Key Provisions
The primary sections of the legislation (AERU 05-30) provide for the description of Class C airspace, which is essentially a repeat of the previous legislative instrument (AERU 05-13). The key requirement under section 1 is the formal establishment of this airspace within the Australian flight information region, detailing its lateral boundaries and altitudes. Section 2 introduces additional comments that allow for the temporary deactivation of Class C airspace to a lower service level, specifically to G class service, without the need for an additional legislative instrument. This is a significant change as it enables more efficient management of airspace by using NOTAMs (Notices to Airmen) or AIP (Aeronautical Information Publication) supplements.
The legislation imposes several obligations on the entities it governs. Firstly, the Civil Aviation Safety Authority (CASA) is required to publish the permanent description of the airspace in the Aeronautical Information Publication (AIP) products and the Designated Airspace Handbook (DAH) as stated in section 3. Section 4 mandates that when a temporary deactivation of the airspace is necessary, this must be managed through the issuance of NOTAMs or AIP supplements, streamlining the process and avoiding the need for further legislative amendments. The changes in section 5 are designed to facilitate a quicker response to requests from entities such as the Bond Springs Gliding Club, which may not need the higher service level provided by air traffic controllers.
In terms of offences and penalties, the legislation does not explicitly outline specific criminal or civil penalties for breaches. However, any failure to comply with the requirements to deactivate airspace or manage airspace services in accordance with the legislation could potentially lead to safety issues, which could result in regulatory actions or sanctions by CASA. The absence of explicit penalties in the text suggests that the primary enforcement mechanism would be through administrative actions, ensuring adherence to the outlined procedures for managing airspace services. The legislative intent appears to focus on streamlining processes and improving operational efficiency rather than imposing punitive measures for non-compliance.
