OAR GAAP Utility Review

The OAR has commissioned the Ambidji Group, in conjunction with Lloyd’s Register, to conduct a review of the utility to Australian airspace management of General Aviation Airport Procedures (GAAP) as used at Bankstown, Camden, Moorabbin, Jandakot, Archerfield and Parafield.

The review will research best practice in other aviation regulatory jurisdictions, and the Classes of airspace and aerodrome procedures documented by ICAO in Annexes and related SARPs.

The review will determine the most appropriate airspace Class or procedure for Australia and provide recommendations to the OAR. Recommendations will be supported by risk assessments and cost-benefit analysis.

Consultation with stakeholders, face to face and through a questionnaire, has been completed. Stakeholder meetings and Hazard Identification Workshops were held during February and March 2009. CASA thanks all those that took part in the consultation process.
