(1) RTCA DO-178C, Software Considerations in Airborne Systems and Equipment Certification, dated December 13, 2011.
(2) RTCA DO-330, Software Tool Qualification Considerations, dated December 13, 2011.
(3) RTCA DO-331, Model-Based Development and Verification Supplement to DO178C and DO-278A, dated December 13, 2011.
(4) RTCA DO-332, Object-Oriented Technology and Related Techniques Supplement to DO-178C and DO-278A, dated December 13, 2011.
(5) RTCA DO-333, Formal Methods Supplement to DO-178C and DO-278A, dated December 13, 2011.
Note: RTCA DO is hereafter referred to as DO.
c. References to use of DO-178C in this AC include use of supplements and DO-330 as applicable.
d. This AC also establishes guidance for transitioning to DO-178C when making modifications to software previously approved using DO-178, DO-178A, or DO-178B.
07/19/2013 AC 20-115C
e. This AC also explains the use of DO-178C for Technical Standard Order (TSO) authorizations.
f. This AC does not obligate the FAA to approve any data or perform any activities as specified within the referenced RTCA documents.
g. If you use the means in this AC as a means of compliance, you must follow it entirely.

Describes the installation and use of a model GA-2A fire extinguisher agent concentration recorder in determining the distribution and concentration of fire-extinguishing agents when discharged in an aircraft powerplant compartment.
Antiskid and Associated Systems
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.
Aircraft Tire Maintenance and Operational Practices
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).
