DO-248C, Supporting Information for DO-178C and DO-278A, published by RTCA, Incorporated, is a collection of Frequently Asked Questions and Discussion Papers addressing applications of DO-178C and DO-278A in the safety assurance of software for aircraft and software for CNS/ATM systems, respectively. Like DO-178C and DO-278A, it is a joint RTCA undertaking with EUROCAE and the document is also published as ED-94C, Supporting Information for ED-12C and ED-109A. The publication does not provide any guidance additional to DO-178C or DO-278A; rather, it only provides clarification for the guidance established in those standards.

While new FAQs and discussion papers have been added, most of the FAQs and discussion papers of DO-248C are carried over from DO-248B. Some of these items have been marked as deleted or updated as the subjects were addressed by the releases of DO-178C, DO-330, supplements, or other publications. An errata section is not included as the release of DO-178C addressed the errata of DO-178B and no DO-178C errata have been published. Initially, this publication was an annual clarification report, DO-248B (2001) was preceded by DO-248A (2000) and DO-248 (1999).
