DO-178B Certifiability is the designation of an avionics component to meet a DEFINED subset of the DO-178B CERTIFICATION requirements, with the remaining certification requirements to be achieved subsequently. DO-178B certification pertains to individual systems, hence requires all software components of a system to be COMPLETED, with each component, and the system, fully meeting all DO-178B requirements. However, in the absence of a completed system, an individual software component (RTOS, graphics library, communications protocol, ETC) can be designated certifiable by subjecting that component to all DO-178B requirements.
