Civil Aviation Authority (CAA) Advisory Circulars (ACs) contain information about standards, practices, and procedures that the Director has found to be an acceptable means of compliance with the associated rule.

Consideration will be given to other methods of compliance that may be presented to the Director. When new standards, practices, or procedures are found to be acceptable they will be added to the appropriate AC.

To order printed copies call 0800 GET RULES (0800 438 785), or order online at link).

From 1 September 2021, we are running a short survey about ACs and how useful they are to participants. You can answer the questions via a pop-up box on each AC page. This survey should only take 3-5 minutes to complete. We would appreciate your feedback and thank everyone who takes the time to respond.
