Reviews of Australian airspace
Reviews are undertaken to ensure the integrity of the airspace architecture.
The OAR is responsible for ensuring that the airspace architecture is appropriate for airspace users and airspace managers within the requirements of the regulatory framework. This is achieved through the review programme.
The programme operates on a cyclic basis with the aim of achieving a review of all of the Australian airspace architecture every 5 years. Reviews can also be triggered by an airspace change proposal or by an aeronautical study.
