Note 2   For an early deactivation that is earlier than 60 minutes before the specified finish time, an amending NOTAM IS required.

Note 3   For an extension to the specified finish time, an amending NOTAM IS required.

Note 4   A pro forma for an activating NOTAM follows:

Reference/year NOTAMN

A) [Insert details]

B) [Insert start time specified in UTC]

C) [Insert finish time specified in UTC]

D) [Insert periods of activity details]

E) [Insert details of Control Zone, including  the following statement:

“active; however may be subject to early deactivation. Check status with [insert details of ATC authority].”]

Overview

The Civil Aviation Safety Authority (CASA) Operational Amendment Regulation 2011 (CASA OAR 152/11), commenced on 17 November 2011, was introduced under regulation 5 of the Airspace Regulations 2007. This regulation was enacted by the Civil Aviation Safety Authority, which is the body responsible for regulating civil aviation safety in Australia. The regulation addresses the classification and control of Australian airspace, ensuring that it is managed in a manner that prioritises aviation safety. CASA OAR 152/11 provides for the determination of various airspace classifications and controlled aerodromes, as well as the temporary reclassification of airspace in certain circumstances. The regulation allows for the establishment of flight information regions, flight information areas, and various classes of controlled airspace, including Class A, B, C, D, and E airspace. It also identifies specific aerodromes as controlled aerodromes and outlines the conditions under which airspace classifications may change temporarily, such as during periods when air traffic control services are suspended or due to emergency conditions. This regulation aims to ensure that Australia's airspace is managed effectively and safely, providing clear guidelines for the control and classification of airspace and aerodromes. The CASA OAR 152/11 is a legislative instrument that was registered before it commenced and was published in the AIP Designated Airspace Handbook on 17 November 2011. This regulation revoked the previous instrument CASA OAR 078/11 and has been amended twice, with CASA OAR 033/12 and CASA OAR 038/12 coming into effect on 9 March 2012 and 16 March 2012, respectively. The amendments made to the regulation include changes to the definitions and airspace classifications, as well as the addition of new provisions for early deactivation of Class C Control Zones. The regulation continues to be in force, with its primary objective being the safe and efficient management of Australian airspace.

Scope and Application

The CASA OAR 152/11 – Determination of airspace and controlled aerodromes etc, made under regulation 5 of the Airspace Regulations 2007, applies to the classification and management of Australian airspace and controlled aerodromes. This legislative instrument delineates specific volumes of airspace and classifies them into various categories such as Flight Information Regions, Flight Information Areas, and different classes of controlled airspace (A to G). Additionally, it designates certain aerodromes as controlled aerodromes, thus subjecting them to specific regulatory oversight. The determinations made by this instrument are applicable to all entities and persons operating within the designated airspaces, including commercial and private aviation operators, air traffic control authorities, and military aviation units. The geographic scope of this Act is nationwide, encompassing the entire airspace over Australian territory, its territorial sea, and the airspace over Australian-controlled territories. The Act's application is further extended through subordinate instruments, such as the amendments CASA OAR 033/12 and CASA OAR 038/12, which modify the initial determinations to align with operational needs and safety standards. These amendments adjust classifications and operational hours, ensuring that the airspace management framework remains effective and responsive to changing circumstances.

Key Provisions

The legislation sets out the classifications and determinations for airspace and controlled aerodromes within Australia. The primary operative sections (sections 4 and 5) detail the classification of various airspaces and the conditions under which these classifications may change. The determinations specify the classification of airspace such as Flight Information Regions (Schedule 1), Flight Information Areas (Schedule 2), and various classes of controlled airspace (Schedules 3 through 9). Additionally, Schedule 10 lists aerodromes that are considered controlled aerodromes. These determinations ensure that the airspace classifications are clearly defined and that the operational parameters for each classification are established. The obligations imposed by the legislation include the requirement for the Controlling Authority, which may be either the Department of Defence – RAAF or Airservices Australia, to manage and control the airspace according to its initial classification. The legislation also mandates that any changes in airspace classification must be communicated through the Aeronautical Information Publication (AIP) or a Notice to Airmen (NOTAM). Furthermore, the legislation outlines the specific conditions under which airspace classifications can change, including changes outside of normal operational hours or due to the suspension of air traffic control services, with provisions for extensions of control where necessary for operational reasons. Breaches of the provisions in this legislation can result in various consequences. Civil Aviation Safety Regulations (CASR) may be enacted to address non-compliance, and in more serious cases, criminal penalties may apply. For example, operating in a controlled airspace without the required permissions or failing to comply with airspace classifications could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The exact penalties depend on the severity of the breach, but they can include fines and other administrative sanctions. In cases where breaches result in safety incidents, more severe penalties, including criminal charges, may be pursued.
