There are many questions related to DO-178B support from T-VEC as well as the implications from the proposed DO-178C. This page provides some information related to these topics, including the important topic of tool qualification, which is required to support a certification effort.

The Global Aviation Traffic Management (GATM), all commercial airborne systems, in addition to all airborne military and space systems (U.S. Air Force 2001), have to comply with FAA regulations for avionics that require DO-178B certification. This now impacts space flight too.

SC-205 is the official designation in the US of the RTCA subcommittee dedicated to updating DO-178B - SOFTWARE CONSIDERATIONS IN AIRBORNE SYSTEMS AND EQUIPMENT CERTIFICATION. This is the primary document on which the FAA certification of all commercial software-based aerospace systems is based. DO-178B was released in 1992 and is mirrored in Europe by ED-12B, the same document but with a European designation. SC-205 is responsible for revising DO-178B/ED-12B to bring it up do date with respect to current software development and verification technologies. The new document will be called DO-178C/ED-12C and is due to be finalized during 2008.
