Explanatory Statement – AERU 05-16/ 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 09 June 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 Aeronautical Information Circular 05-16, concerning Class D Control Zones, was enacted in 2005, providing a legal framework for the establishment and description of airspace around aerodromes to ensure safe instrument flight operations. This legislative instrument aims to update and codify the airspace descriptions necessary for the implementation of instrument flight rules (IFR) and visual flight rules (VFR) within the Australian flight information region. The instrument was issued by the relevant federal authority and is designed to support the safe and efficient management of air traffic, particularly around aerodromes where instrument meteorological conditions are a factor. The policy objective of this instrument is to ensure that the airspace around aerodromes is clearly defined and accessible to pilots, thereby enhancing aviation safety and operational efficiency.
Scope and Application
The F2005L01165 legislative instrument, which pertains to Class D Control Zones, is designed to provide a legal framework for airspace modifications, ensuring that all changes to airspace receive the necessary formal recognition through a duly signed Legislative Instrument. This Act applies to the management and description of airspace within Australia, including the lateral and vertical limits and other relevant details, which are published in the AIP MAP products and the Designated Airspace Handbook (DAH). The DAH is updated approximately every 24 to 28 weeks, providing a comprehensive tabular description of airspace volumes. These Class D Control Zones are specifically designated to accommodate the flight paths of IFR flights arriving and departing from aerodromes under instrument meteorological conditions, ensuring safety and efficiency in air traffic operations. The legislation operates within the Australian flight information region and has a limited impact, as it pertains to existing IFR and VFR operations without introducing new additions. Given the negligible impact on businesses, a Regulation Impact Statement was deemed unnecessary by the Office of Regulation Review.
Key Provisions
The main operative sections of this legislation (F2005L01165) pertain to the establishment and description of Class D Control Zones, as detailed in the Designated Airspace Handbook (DAH). Section 3 of the legislation mandates the permanent description of airspace, including Class D Control Zones, and its publication in the DAH. This permanent description is also to be published in the Aeronautical Information Publication (AIP) MAP products, as outlined in ICAO Annex 15. The legislative instrument specifically references the Class D Control Zones, which become effective from 09 June 2005, detailing their lateral and vertical limits and other pertinent information.
The Act imposes several obligations on the parties and entities it governs. Primarily, it mandates the publication and maintenance of the permanent description of airspace, including Class D Control Zones, in both the AIP MAP products and the DAH. This ensures that all stakeholders, including pilots, air traffic controllers, and aviation authorities, have access to up-to-date and accurate information regarding the airspace. The DAH, which is issued on an approximate 24/28 week cycle, serves as a critical reference for understanding the lateral and vertical limits of these zones. Additionally, the legislation ensures that these zones are designed to accommodate Instrument Flight Rules (IFR) flights arriving and departing from aerodromes under instrument meteorological conditions.
Breaches of this legislation may have civil and criminal consequences, although specific offences and penalties are not detailed in the explanatory statement. Given that the primary focus of the Act is on the legal definition and publication of airspace, non-compliance could potentially lead to safety risks in the air traffic management system. This might include legal action for inaccuracies in airspace descriptions, which could be deemed as breaches of aviation safety regulations. However, the maximum penalties for such breaches are not explicitly stated in the provided explanatory statement. Nonetheless, the seriousness of airspace management necessitates strict adherence to the legislative requirements to avoid any adverse impact on aviation safety and operations.
