Approval of Flight Guidance Systems
This advisory circular (AC) describes an acceptable means for showing compliance with certain requirements of Title 14, Code of Federal Regulations (CFR) 25.1329, Flight guidance systems. While part 25 contains the airworthiness standards applicable to transport category airplanes, the guidance in this AC pertains to the functions of autopilots, flight directors, and automatic thrust control as well as any interactions with stability augmentation and trim functions. This revision incorporates minor changes associated with issuance of the final rule for Airplane and Engine Certification Requirements in Supercooled Large Drop, Mixed Phase, and Ice Crystal Icing Conditions.

Airworthiness Criteria for the Approval of Airborne Windshear Warning Systems in Transport Category
This advisory circular (AC) provides guidance for the airworthiness approval of airborne windshear warning systems in transport category airplanes. Like all advisory circular material, this advisory circular is not, in itself, mandatory and does not constitute a regulation. It is issued for guidance purposes and to outline a method of compliance with the rules. In lieu of following this method without deviation, the applicant may elect to follow an alternate method, provided the alternate method is also found by the Federal Aviation Administration (FAA) to be an acceptable means of complying with the requirements of Part 25 of the Federal Aviation Regulations (FAR). Because the method of compliance presented in this AC is not mandatory, the terms "shall" and "must" used in this AC apply only to an applicant who chooses to follow this particular method without deviation.
Airplane Flight Manual
Identifies the information that must be provided in Airplane Flight Manual (AFM) under the airworthiness regulations and provides guidance as to the form and content of the approved portion of an AFM.
Aeroelastic Stability Substantiation of Transport Category Airplanes
This advisory circular (AC) provides guidance material for acceptable means, but not the only means, of demonstrating compliance with the provisions of Title 14, Code of Federal Regulations part 25 associated with the design requirements for transport category airplanes to preclude the aeroelastic instabilities offlutter, divergence, and control reversal. The precise details for analytical procedures and testing techniques are beyond the scope of this AC. However, some general information is included, with supporting discussions, for consideration when demonstrating compliance with§ 25.629 and related regulations. Revision B incorporates changes only to the portions of this AC affected by the Airplane and Engine Certification Requirements in Supercooled Large Drop, Mixed Phase, and Ice Crystal Icing Conditions final ru
