DO-178C, Software Considerations in Airborne Systems and Equipment Certification is the primary document by ... Examples might include causing passenger inconvenience ...
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.
The Advisory Circular revisions C and D are considerably longer, giving guidance in modifying and re-using software previously approved using DO-178, DO-178A, or DO-178B (preceding revisions of the DO-178 standard). Additionally, the expanded AC now provides guidance for Field Loadable Software and User Modifiable Software within aircraft software.
The Software Level, also termed the Design Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [2]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The failure ...
Some representative standards include MIL-STD-2167 for military systems, or RTCA DO-178B and its successor DO-178C for civil aircraft. The regulatory requirements for this software can be expensive compared to other software, but they are usually the minimum that is required to produce the necessary safety.

RTCA DO-178C and RTCA DO-254 form the basis for flight certification today, while DO-297 gives specific guidance for Integrated modular avionics. ARINC 653 contributes by providing a framework that enables each software building block (called a partition) of the overall Integrated modular avionics to be tested, validated, and qualified ...
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 [1] in the safety assurance of software for aircraft and software for CNS/ATM systems, respectively.
