This advisory circular (AC) provides recommended tire care and maintenance practices needed to assure the safety of support personnel and the continued airworthiness of aircraft. Specifically, this AC provides guidance on the installation, inflation, maintenance, and removal of aircraft tires. In addition, this AC provides guidance on those operational practices necessary to maintain safe aircraft operations. This AC is not mandatory and does not constitute a regulation. It is issued for guidance purposes and to outline acceptable tire maintenance and operational practices. In lieu of following this method without deviation, operators may elect to follow an alternative method that has also been found acceptable by the Federal Aviation Administration (FAA).

 This Advisory Circular (AC) provides guidance for the installation and airworthiness approval of Automatic Dependent Surveillance – Broadcast (ADS-B) Out systems in aircraft.

 

This advisory circular (AC) provides guidance material for the airworthiness approval of installed positioning and navigation equipment. This revision corrects minor errors, clarifies guidance, adds a frequently asked question section, and updates technical standard order (TSO) information. Major changes in this AC reflect TSO-C129a cancellation; updated guidance related to TSO-C115c; clarifying information in paragraphs 14-6.8 and 14-8.13 for the ground proximity warning system/terrain awareness and warning system (GPWS/TAWS) glideslope alerting function, and adding additional testing procedures in Appendix 4 for global navigation satellite systems (GNSS) that support automatic dependent surveillance - broadcast (ADS-B).

This advisory circular (AC) provides guidance on airworthiness approval for designers, manufacturers, and installers of satellite voice equipment supportingair traffic service (ATS).  In this AC, the Federal Aviation Administration (FAA) recommends one way to gain airworthiness approval for satellite voice equipment.  This AC is not mandatory and does not constitute a regulation.  This AC describes an acceptable means, but not the only means, to gain airworthiness approval for your satellite voice equipment.  However, if you use the means described in this AC, you must follow it in its entirety.

Provides guidance material for the airworthiness and operational approval of Traffic Alert and Collision Avoidance Systems (TCAS II) and Mode S transponders. Like all AC material, this AC is not mandatory and does not constitute a regulation. Issued for guidance purpose and to outline a method of compliance with the rules.

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 and guidance regarding airworthiness and operational approval of airborne equipment/systems in accordance with FAR 135.153(b) and (c).

This advisory circular (AC) provides guidance on compliance with the applicable Regulations for the airworthiness and operational approval for digital flight data recorder systems (DFDRS).

This advisory circular (AC) provides information on certification (design and installation) and continued airworthiness of digital flight data recorder systems (DFDRS). DFDRS provide information for an investigative authority—the National Transportation Safety Board (NTSB) in the United States—to conduct more thorough investigations of accidents and incidents. The data recorded is also used by operators to enable the prediction of trends that may be useful in determining modifications needed to avoid accidents and incidents.

This AC provides information to applicants for a supplemental type certificate (STC), and to individuals who are responsible for establishing and maintaining compliance under the operating rules for digital flight data recorders (DFDR). Aircraft manufacturers who intend to install DFDRs in newly manufactured aircraft could also use this information.

This AC is not mandatory and is not a regulation. This AC describes an acceptable means, but not the only means, to comply with Title 14 of the Code of Federal Regulations (14 CFR).

 

On January 11,1993, we, the Federal Aviation Administration (FAA), published Advisory Circular (AC) 20-115B recognizing RTCA/DO-178B, Software Considerations in Airborne Systems and Equipment Certification, dated December 1, 1992, as a means, but not the only means, to seek FAA approval of airborne software. RTCA/DO-178B is recognized by industry and certification authorities as an accepted approach for assuring that software in airborne systems and equipment has been developed to meet the safety objectives of the regulations.

 

This AC identifies what you, as an applicant, will have to address and document when you propose an alternative approach to that defined in RTCA/DO-178B. This AC is intended to provide you, the applicant, with guidance on how to establish that your proposed alternative provides the same level of assurance as that provided in RTCA/DO-178B for airborne software.  Your proposed alternative should be evaluated in conjunction with the certification process and applied to airborne systems and equipment (containing software) for which you are seeking FAA approval in order to obtain a Type Certificate, Supplemental Type Certificate, Amended Type Certificate, or Amended Supplemental Type Certificate.

Includes information relating to the Society of Automotive Engineers (SAE) standard dimensions for fueling ports now being incorporated during new aircraft production by all General Aviation Manufacturer’s Association member companies. It also makes recommendations to the fuel suppliers and Fixed Base Operators to change their fuel dispensing nozzles to meet the dimensions referenced in the SAE standard.

Provides an acceptable means, but not the only means, of complying with the requirement that anti-skid and associated systems must be designed so that no probable malfunction will result in a hazardous loss of braking or directional control of an airplane.

This advisory circular (AC) provides guidance applicable to adding fuels and oils as engine, aircraft, or auxiliary power unit (APU) operating limitations.  It also provides acceptable methods, but not the only methods, that may be used to approve aircraft, engines, or APUs to operate with specified propulsion fuels and lubricating oils.
