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.
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.
Although technically a guideline, it was a de facto standard for developing avionics software systems until it was replaced in 2012 by DO-178C. The Federal Aviation Administration (FAA) applies DO-178B as the document it uses for guidance to determine if the software will perform reliably in an airborne environment, [ 1 ] when specified by the ...
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.
Given ASIL is a relatively recent development, discussions of ASIL often compare its levels to levels defined in other well-established safety or quality management systems. In particular, the ASIL are compared to the SIL risk reduction levels defined in IEC 61508 and the Design Assurance Levels used in the context of DO-178C and DO-254. While ...
President Donald Trump on Thursday took executive action to address FAA hires and aviation safety after an Army Black Hawk helicopter collided with a passenger jet in D.C.
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.
