DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the primary document by which the certification authorities such as FAA, EASA and Transport Canada approve all commercial software-based aerospace systems.
Test coverage is one consideration in the safety certification of avionics equipment. The guidelines by which avionics gear is certified by the Federal Aviation Administration (FAA) is documented in DO-178B [16] and DO-178C. [18] Test coverage is also a requirement in part 6 of the automotive safety standard ISO 26262 Road Vehicles - Functional ...
MC/DC is used in avionics software development guidance DO-178B and DO-178C to ensure adequate testing of the most critical (Level A) software, which is defined as that software which could provide (or prevent failure of) continued safe flight and landing of an aircraft.
These position papers were among the inputs to the joint RTCA/EUROCAE committee that developed DO-178C, DO-278A, DO-248C, and DO-330, and the technology supplements to these publications (DO-331, DO-332, and DO-333). [1] The model for international certification authority harmonization has changed since CAST's inception. [5]
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 ...
The replacement content published in FAQ #81 in DO-248C Supporting Information for DO-178C and DO-278A provides a shorter list of certification concerns for combining (or merging) these two "what" and "how" levels into a single set of requirements without distinguishing the relevant certification objectives of the two levels. FAQ #81 also ...
The Advisory Circular AC 20-115( ), Airborne Software Development Assurance Using EUROCAE ED-12( ) and RTCA DO-178( ) (previously Airborne Software Assurance), recognizes [1] the RTCA published standard DO-178 as defining a suitable means for demonstrating compliance for the use of software within aircraft systems.
Various standards suggest different levels, e.g. Software Levels A-E in DO-178C, [4] SIL (Safety Integrity Level) 1-4 in IEC 61508, [1] ASIL (Automotive Safety Integrity Level) A-D in ISO 26262. [2] The assignment is typically done in the context of an overarching system, where the worst case consequences of software failures are investigated.
