What is a Reusable Software Component?

_______________

A DO-178B/C Reusable Software Component (RSC) is a software collection that is recognized as meeting the requirements of RTCA/DO-178B/C and that may be used on more than one project without having to regenerate certification artifacts.

The FAA grants RSC acceptance as part of a normal certification process, provided that the applicant complies with the guidance policy defined in FAA Advisory Circular AC 20-148. The acceptance allows future users of the DO-178B/C RSC to deploy the software without the added cost and risk of re-certification. This applies to components such as operating systems and networking protocols, that can then be reused (in unadulterated form) across hardware platforms.
