DO-254 Benefits Versus Costs

DO-254, the design assurance guideline for airborne electronic hardware, is considered by many to be a simple cut/paste of DO-178, its avionics software sibling. Surely, as with wine and beer, both are fermented liquids which become increasingly expensive with increased complexity. While similarities abound, so do...
