Office of Airspace Regulation (OAR)

The Airspace branch of the division is referred to as the Office of Airspace Regulation (OAR).

The OAR exercises powers under the Airspace Regulations (2007) to regulate and administer Australian airspace, including prohibited, restricted and danger areas, where certain types of activities take place that may present a risk to aviation activities. Australian airspace administration is generally aligned with ICAO airspace classes and associated air traffic services Airservices Australia and the Department of Defence provide those air traffic services. More information about the classes of airspace and airspace management is available from Airservices Australia. The OAR also provides a regulatory function for the published air routes.

The OAR is divided into two teams: airspace reform and airspace operations. The airspace reform team reviews the airspace architecture and recommends changes as appropriate whereas the airspace operations team focus is on the day to day airspace change needs as well as the implementation of permanent changes to the airspace architecture.

Communications, navigation, surveillance/air traffic management

Airspace capacity is determined by the combined capabilities of the communications, navigation, surveillance and air traffic management systems (CNS/ATM) in place. These include ground and aircraft-based systems. Advanced technologies enabled by immediate and accurate satellite signals are improving safety and efficiency in air traffic management and harmonising Australian operations with global standards.

The section below contains important information on current procedures, aircraft equipment and safety information for satellite-base technology systems used for communications, navigation and surveillance.

Make sure your aircraft is certified, equipped and approved for standard performance-based navigation (PBN) specifications.

Lean about the equipment, capabilities and flight planning requirements for automatic dependent surveillance–broadcast (ADS-B).
