It's a written document setting out what the FAA considers to be "best
practices" for aviation.

Is see the Aviation Information Manual as an attempt to summarize and
integrate the Federal Aviation Regulations and FAA Order 7110.65 and

Advisory Circulars are not regulatory instruments either, but they are
cited in FAA enforcement actions.
