Certification Guidance for Installation of Non-Essential, Non-Required Aircraft Cabin Systems & Equipment (CS&E)
This AC provides the primary certification guidance on how to meet the airworthiness requirements for installation of non-essential, non-required aircraft cabin systems & equipment (CS&E). We incorporate in this AC the guidance in RTCA, Inc. document RTCA/DO-313, Certification Guidance for Installation of Non-Essential, Non-Required Aircraft Cabin Systems & Equipment, dated October 2, 2008. We also clarify certain guidance in RTCA/DO-313. (See paragraph 6.)
This AC is not mandatory and does not constitute a regulation. In it we describe a means, though it is not the only means, for manufacturers and installers to show their equipment design and installation performs its intended function. If you use the means described in this AC, however, you should follow it in all respects.

This advisory circular (AC) shows you how to obtain Federal Aviation Administration (FAA) airworthiness approval for the development, verification, and integration of an integrated modular avionics (IMA) system for installation into an aircraft or engine. We cite RTCA, Inc. document RTCA/DO-297, Integrated Modular Avionics (IMA) Development Guidance and Certification Considerations, dated November 8, 2005 and supplement it with this text. This AC also provides guidance on how to show compliance with Technical Standard Order (TSO)-C153, Integrated Modular Avionics Hardware Elements.
This AC is not mandatory and does not constitute a regulation. In it, we describe an acceptable means, though it is not the only means, to obtain FAA approval of IMA systems.
This AC uses the terminology “should” when discussing compliance to the AC itself, as the AC represents one, but not the only, method of complying with the regulations. This AC uses the term “must” when discussing compliance to the regulations, as compliance to a regulation is not optional. In these cases, the AC text supplies, in square brackets, a reference to the specific rule(s) being discussed.
Alternatives to RTCA/DO-178B for Software in Airborne Systems and Equipment
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.
