In contrast, the Advisory Circular (AC) issued by the FAA is a type of publication issued by the Federal Aviation Administration (FAA) that provides guidance for compliance with airworthiness regulations, pilot certification, operational standards, training standards, and other regulations within 14 CFR Aeronautics and Space Title. In general, advisory circulars have no binding or regulatory force, but some have the effect of de facto, such as standards and regulations.
