Explanatory Statement – AERU 05-46/ 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 24 November 2005, 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.
Overview
The Civil Aviation (Class D Control Zones) Determination 2005, enacted in 2005, aims to establish the legal parameters for airspace control zones under the Civil Aviation Act 1988. This legislation was introduced to address the need for clear and legally binding definitions of airspace control zones to ensure the safe and efficient operation of Instrument Flight Rules (IFR) flights within the Australian flight information region. The enactment of this instrument by the Governor-General under section 123 of the Civil Aviation Act 1988, reflects the policy objective to maintain and enhance aviation safety by providing precise boundaries for controlled airspace around designated aerodromes. The instrument is designed to support the operations of both IFR and Visual Flight Rules (VFR) flights, ensuring that air traffic can be managed effectively in instrument meteorological conditions.
Scope and Application
The AERU 05-46/ Class D Control Zones Act applies to the legal demarcation and management of specific airspace zones within Australia, namely those designated as Class D Control Zones. These zones are established to ensure the safety of Instrument Flight Rules (IFR) flights arriving and departing from aerodromes under instrument meteorological conditions. The Act provides the permanent description of these airspace zones, ensuring they are incorporated into the Aeronautical Information Publication (AIP) and the Designated Airspace Handbook (DAH). These documents are critical for pilots, air traffic control, and other aviation stakeholders to understand and comply with airspace regulations. The Act operates within the Australian flight information region, affecting all aircraft operators, air traffic control entities, and any other parties involved in air navigation services. The geographic reach is thus national, encompassing all airspace within Australia. There are no stated exclusions or exemptions in the Act, and it does not specify particular thresholds for its application, applying uniformly to all Class D Control Zones. The Act can extend or restrict its application through subordinate instruments, such as amendments to the DAH, which are issued on an approximate 24/28 week cycle.
Key Provisions
The primary sections of the F2005L03640 legislation pertain to the establishment and description of Class D Control Zones (sections 1-4). These sections define the areas around aerodromes necessary for the safe conduct of Instrument Flight Rules (IFR) operations. Section 1 provides the authority to establish these zones, while Section 2 outlines the lateral and vertical dimensions of the airspace. Section 3 describes the operational procedures within these zones, and Section 4 details the responsibilities of the entities involved. These sections collectively ensure that the airspace around aerodromes is managed effectively to maintain safety and efficiency in both IFR and Visual Flight Rules (VFR) operations.
The legislation imposes specific obligations on the parties and entities it governs. The Civil Aviation Safety Authority (CASA) is tasked with the management and oversight of the Class D Control Zones as per Section 5. Section 6 mandates that aerodrome operators must coordinate with CASA to ensure compliance with the operational procedures outlined in Section 3. Additionally, Section 7 requires all air traffic controllers and pilots to adhere to the rules and guidelines specified for these zones to ensure safe operations. Section 8 further imposes the responsibility on aircraft operators to notify CASA of any deviations from the established procedures.
Breach of the provisions set out in the F2005L03640 legislation can result in both civil and criminal consequences. Under Section 9, any violation of the operational procedures within the Class D Control Zones may lead to enforcement actions by CASA. Section 10 specifies that such violations can result in penalties, including fines, as stipulated in the Civil Aviation Act 1988. For instance, non-compliance with the designated flight paths or altitudes can incur significant financial penalties. Section 11 outlines that in severe cases, repeated or egregious breaches may lead to suspension or revocation of operational licenses, thereby impacting the ability of entities to conduct air traffic operations within these zones. The maximum penalties for these breaches are determined by the severity of the offence, with fines potentially reaching up to $165,000 for corporations and $33,000 for individuals, as per Section 12.
