Integrated Modular Avionics Development. Verification, Integration and Approval using RTCA/DO-297 and Technical Standard Order C153
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.

We don’t cover electronic components installed independent of the seat.
b. 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 gain approval to install electronic components integrated in seats on aircraft. However, if you use the means described in the AC, you must follow it in all important respects.

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. 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.
