The Office of Airspace Regulation (OAR) is responsible for:

  • providing advice to CASA on airspace regulation and review of airspace classifications
  • designation and reviews of protective airspace (prohibited, restricted and danger areas)
  • designation of air routes and airways and their conditions of use
  • assessment of proposals for permanent and temporary airspace changes.

Proposed changes to the Australian airspace architecture are managed through the airspace change process.

OAR Strategic Work Plan

The OAR Strategic Work Plan (currently under review) details the OAR priorities, processes and strategies over the next five years to ensure that Australian airspace complies with the Airspace Act 2007 and Airspace Regulations 2007.

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.

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