Which publication is nonbinding and aims to inform the public about aviation practices?

The correct answer is the Advisory Circular. Advisory Circulars are publications issued by the FAA to provide guidance and information on best practices, policies, and safety measures related to aviation. They are designed to inform stakeholders, including the public, about various aviation topics without constituting mandatory regulations.

These documents serve an important role in disseminating knowledge about aviation practices, operational procedures, and safety guidance, all while allowing for flexibility and discretion in implementation. Since they are nonbinding, they don’t impose legal obligations but rather offer recommendations to help promote safety and efficiency within the aviation community.

Other publications, such as the Aeronautical Information Manual and the Automated Terminal Information Service, serve specific purposes like providing essential flight information or terminal advisories, but they do not have the same nonbinding and educational nature as Advisory Circulars.
