What are Advisory Circulars used for?

Advisory Circulars (ACs) are documents produced by the Federal Aviation Administration (FAA) that serve to communicate non-regulatory information and guidance to the public. These publications can cover a wide array of topics, including best practices, operational standards, safety recommendations, and information on new technologies or procedures.

The purpose of an Advisory Circular is to offer guidance that may not carry the force of law but is intended to help individuals and organizations comply with regulations in an efficient manner. This means that while they provide valuable insight and recommendations, they do not establish enforceable requirements like regulations do. Therefore, the choice stating that they inform the public of non-regulatory material accurately captures their role in aviation by emphasizing their advisory nature, which is crucial for enhancing safety and operational efficiency in the industry.
