PURPOSE.
This order guides Aircraft Certification Service (AIR) field
offices and Designated Engineering Representatives (DER) on how to
apply RTCA/DO-178B, "Software Considerations in Airborne Systems
and Equipment Certification," for approving software used in
airborne computers. Advisory Circular (AC) 20-115B, "RTCA, Inc.
Document RTCA/DO-178B," recognizes RTCA/DO-178B as an acceptable
means of compliance for securing the Federal Aviation
Administration's (FAA) approval of software in airborne systems and
equipment. This order establishes guidelines for approving software
in compliance with RTCA/DO-178B. The guidelines are applicable to
the approval of airborne systems and equipment and the software
aspects of those systems related to type certificates (TC),
supplemental type certificates (STC), amended type certificates
(ATC), amended supplemental type certificates (ASTC), and technical
standard order (TSO) authorizations.
