Air Force Instruction

An Air Force Instruction (AFI) is a documented instruction for members of the United States Air Force intended for use by active duty, guard, and reserve members and associated civilians. It is one of many forms of directives published by the Air Force Departmental Publishing Office (AFDPO). In almost all cases, an Air Force Instruction is a form of a general order; and violation of the AFI by an Airman subject to it can be punished under the Uniform Code of Military Justice.

Examples
Some examples of an Air Force Instruction is AFI 11-202 General Flight Rules which specifies operational flying procedures; AFI 36-2903 Dress and Appearance of Air Force Personnel which outlines Air Force uniform wear and grooming standards; AFI 36-2618 Enlisted Force Structure which explains each enlisted rank in the U.S. Air Force, and the expectations and responsibilities for each; and AFI 36-2905 Fitness Program which explains the Air Force Fitness program and describes how it is to be implemented.

Air Force members are required to know, understand, and implement AFIs which apply to their duties and responsibilities.
