Part 25 contains the airworthiness standards applicable to transport category airplanes a. Installing a primary ice detection system; b. Developing visual cues and installing an advisory ice detection system to alert the flightcrew that the airframe ice protection system (IPS) must be activated; c. Identifying conditions conducive to airframe icing through the use of temperature and visible moisture cues; and d. Including in the airplane flight manual (AFM) procedures for activating and deactivating the airframe IPS.

This advisory circular (AC) provides information for production approval holders (PAH) under Title 14, Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products, Articles, and Parts. This AC guides PAHs in developing and maintaining quality systems for the products and articles they produce. This guidance aids the applicant for a production approval or current PAH in developing a quality system that both meets the needs of the PAH and is compliant with the regulations. You can find this AC at http://www.faa.gov/regulations_policies/advisory_circulars/.

a. This advisory circular (AC) provides information about Title 14, Code of Federal Regulations (14 CFR), part 45, Identification and Registration Marking. This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to comply with the requirements for identifying aircraft, aircraft engines, or propellers with identification plates, and marking aircraft with nationality and registration marks. However, if you use the means described in the AC, you must follow it in all important respects.

b. A list of other related sections of 14 CFR and related publications, and definitions pertinent to this AC are located in the appendixes to this AC.

 

This advisory circular (AC) sets forth an acceptable means of showing compliance with Title 14 Code of Federal Regulations (14 CFR), part 23, for the certification of airplanes originally certificated to either European Aviation Safety Agency (EASA) CS-VLA or Joint Aviation Requirements (JAR) JAR-VLA.

Provides information that airports can use to procure foreign object debris (FOD) detection equipment. Contains minimum performance specifications for systems and equipment that detect foreign objects on airports, including stationary radar, stationary electro-optical, stationary hybrid radar and electro-optical, and mobile radar.

Provides guidance to the public on the design and evaluation of pavements at civil airports.

Because of the size of the document, it is available as one large file (see Complete) or as four smaller files (see Parts 1-4).

Contains the FAA standards for power and control units for land and hold short lighting systems.

Version E updates Item P-620, Runway and Taxiway Painting, to include new information on Preformed Thermoplastic Airport Pavement Markings and Application—Preformed Airport Pavement Markings; clarifies that Prohibited Materials cannot exceed permissible limits as specified in relevant Federal Regulations; adds Item P-621, Saw-Cut Grooves; and updates references to Saw-Cut Grooves in Items P-401, Plant Mix Bituminous Pavements, and P-501, Portland Cement Concrete.

Because of the size of this document, it is available as a single file (see Complete) and as three smaller files. See Construction Standards for Airports to access individual files for each item or part.

Provides guidelines and procedures for measuring and evaluating runway roughness as identified by surface profile data of rigid and flexible airport pavements. Provides technical procedures to quantify surface irregularities and to determine how surface irregularities may affect specific categories of airplanes.

This Advisory Circular (AC) provides information about Title 14, Code of Federal Regulations (14 CFR) part 21, Certification Procedures for Products and Parts, § 21.191(g) for the purpose of operating amateur-built aircraft.

Furnishes general guidance for airport employees, airport management, and other personnel responsible for aircraft rescue and firefighting (ARFF) operations at the scene of an aircraft accident on the proper preservation of evidence.  It explains the need for preservation of evidence and details operational actions which may be permitted if performed in the interest of preserving life.

This advisory circular (AC) provides applicants guidance for obtaining an airworthiness approval for traffic alert collision avoidance systems (TCAS II). It also provides guidance for certification of a stand-alone Mode S transponder system. This AC includes the TCAS II version 7.0 plus the new version 7.1 and performance standards for the optional functionality of TCAS II hybrid surveillance.

Provides information on courses and reference materials for training of Aircraft Rescue and Firefighting (ARFF) personnel.

Provides guidance on airport related signs and graphics. Recommends use of 'Guidelines for Airport Signing and Graphics' (American Association of Airport Executives, the Airports Council International - North America, the Air Transport Association of America, and the Airport Consultants Council, 2001) in designing airport terminal signing systems until an updated manual, currently being developed under the Airport Cooperative Research Program, is available. At international airports, also recommends International Civil Aviation Organization (ICAO) Document 9636, 'International Signs to Provide Guidance to Persons at Airports and Marine Terminals (1995)'.

This AC sets forth an acceptable means, but not the only means of showing compliance with the provisions of Title 14 of the Code of Federal Regulations (14 CFR) parts 23, 25, 27, and 29 regarding airworthiness type certification requirements for composite aircraft structures involving fiber reinforced materials, e.g., carbon and glass fiber reinforced plastics. Guidance information is also presented on the closely related design, manufacturing, and maintenance aspects. The information contained herein is for guidance purposes and is not mandatory or regulatory in nature. 

This advisory circular (AC) describes a comparative test and analysis method that may be used for turbine engine or auxiliary power unit (APU) blades or vanes when produced under parts manufacturer approval (PMA). PMA applicants may use this comparative modal and high-cycle fatigue (HCF) method to show the vibratory stresses and HCF capability of their proposed blades or vanes are equivalent to those of the type design parts. This method supports showing that the engine or APU still complies with part 33 of Title 14 of the Code of Federal Regulations (14 CFR part 33) or Technical Standard Order (TSO) C77.
