Code of Federal Regulations and Advisory Circulars 

Code of Federal Regulations - The FAA publishes the Code of Federal Regulations (CFR) to make readily 

available to the aviation community the regulatory requirements placed upon them. These regulations are sold 

as individual parts by the Superintendent of Documents. 
The more frequently amended parts are sold on subscription service with subscribers receiving changes 

automatically as issued. Less active parts are sold on a single

−

sale basis. Changes to single-sale parts will be sold 

separately as issued. Information concerning these changes will be furnished by the FAA through its Status of 

Federal Aviation Regulations, AC 00

−

44. 

Advisory Circulars - The FAA issues Advisory Circulars (AC) to inform the aviation public in a systematic way 

of nonregulatory material. Unless incorporated into a regulation by reference, the contents of an advisory circular 

are not binding on the public. Advisory Circulars are issued in a numbered subject system corresponding to the 

subject areas of the Code of Federal Regulations (CFR) (Title 14, Chapter 1, FAA). 

NOTE

Current AC information can be found at: https://www.faa.gov/regulations_policies/advisory_circulars/. 

External References - All references to Advisory Circulars and other FAA publications in the Aeronautical 

Information Manual include the FAA Advisory Circular or Order identification numbers (when available). 

However, due to varied publication dates, the basic publication letter is not included.
