Adelaide airspace review
CASA’s Office of Airspace Regulation has engaged Hyder Consulting Pty Ltd to conduct an independent review of the airspace within 50 nautical miles of Adelaide to ensure airspace arrangements remain safe and meet air traffic demand. The review will determine the appropriateness of the current airspace classifications and the air traffic services provided, review access for all types of airspace users and provide recommendations to address any issues of the current airspace architecture. The review will assess the type and frequency of operations in the area with particular emphasis on passenger transport operations. All recommendations will be supported by risk assessments and cost-benefit analysis. Industry briefings have been held in Adelaide. Once complete, the review will be available on this website.
