DO-248

Article summary

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. The present revision is also expanded to include the "Rationale for DO-178C/DO-278A" section to document items that were considered when developing DO-178B and then DO-178C, DO-278A, and DO-330, as well as the supplements that accompany those publications (DO-331, DO-332, DO-333). Corresponding with the releases of DO-178C and DO-278A, the present revision, DO-248C, is an update to the previous revision DO-248B, Report for Clarification of DO-178B "Software Considerations in Airborne Systems and Equipment Certification". 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.…
