Specifically what objectives are required to meet certification for Level D...which is only 'minor' criticality.

I can't seem to find anything, in the public, that points to what the objectives are for Level D. I'm hopeful that a general purpose OS would meet whatever the criteria are.

Disclaimer: you must consult with a certification professional or with your certification authorities for getting a formal decision.

Since your question regarding the objectives for Level D is too general, I’ll focus only on operating system: DO-178B does not specify any requirement on an operating system. Actually an OS is considered just as any other software. Nevertheless, DO-178B does specify an objective, relevant also for Level D development, which OS can come handy: partitioning of resources (space and time) and confirming its integrity.

  • I believe my question was pretty darn specific. Is a RTOS required to get certified at DO-178B Level D? The fact that this question can't get answered is part of the problem with all of the DO-178B/C junk. If it is up to someone's interpretation of Level D - well, what's the point? In the end, I don't believe it it to be required. But I've yet to decipher what 'partitioning' means within the scope of a 'general purpose' OS (e.g. Linux). – Kit Plummer May 13 '19 at 20:03
