Guidance for how to submit an Airspace Change Proposal, including a new webform, have been updated to provide greater clarity.

The issue

CASA’s Office of Airspace Regulation  (OAR) is responsible for the administration of the Australian airspace architecture under the Airspace Act 2007 and Airspace Regulations 2007.

Changes to Australian airspace, including both permanent and temporary changes, are made through a structured airspace change process. Anyone can propose an airspace change by submitting an Airspace Change Proposal (ACP). It could be for emergencies, temporary activities such as military training exercises and air shows or permanent airspace changes.


The CASA website includes detailed guidance on the airspace change process and how to prepare and submit an ACP. Information that must be prepared by a proponent include an airspace risk assessment that is appropriate for the size and complexity of the proposed change as well as evidence of consultation with airspace users.

Guidance on preparing an ACP has recently been updated to provide greater clarity to proponents about the information they need to prepare when submitting an ACP and how it will be assessed. The ACP form has also recently been updated to provide greater clarity on the information required. 

For further information, see the CASA website.

This post will be 'open' on AvSEF for two weeks.
