Consequently, tool qualification guidance was removed in DO-178C, replaced therein with guidance for deciding when to apply DO-330 tool qualification guidance to tools used in a DO-178C context. [16] Technology supplements were added to extend the guidance of the DO-178C document to specific techniques. Rather than expanding the prior text to ...
Many of RTCA documents begin with the letters DO which stands for DOcument. RTCA develops Minimum Operating Performance Standards for aviation-based technology (typically avionics) but has developed standards for such far-ranging topics as Airport Security, Counter UAS Detection standards, and Aircraft Cockpit and Cabin Cleaning standards.
It is a misunderstanding that by purely syntactic rearrangements of decisions (breaking them into several independently evaluated conditions using temporary variables, the values of which are then used in the decision) which do not change the semantics of a program can lower the difficulty of obtaining complete MC/DC coverage.
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.
The Certification Authorities Software Team (CAST) is an international group of aviation certification and regulatory authority representatives. The organization of has been a means of coordination among representatives from certification authorities in North and South America, Europe, and Asia, in particular, the FAA and EASA.
RTCA published the document as RTCA/DO-178B, while EUROCAE published the document as ED-12B. Although technically a guideline , it was a de facto standard for developing avionics software systems until it was replaced in 2012 by DO-178C .
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.
