FAA advisory circulars containing subject matter specifically related to airmen are issued under 70 subject number.
Advisory Circulars are educational materials created by the Federal Aviation Administration to educate and direct organisations and people in the aviation sector as well as the general public. Advisory Circulars are meant to be educational rather than regulatory, although frequently they contain recommendations or actions that the FAA expects to be carried out or heeded.
The FAA can provide ACs to a range of users, including pilots, mechanics, operators, airport managers, manufacturers, and the general public. Aviators, airports, flying schools, pilots, operations, or maintainers are frequently the focus of advice circulars. Directional, informative, or descriptive advisory circulars are all possible. They frequently explain how the FAA thinks things should be done, recommended operating procedures, or provide explanation of a new regulation.
