Plain-English Explainer

Where it applies

The FAA circular describes an acceptable route for applying RTCA DO-178 and EUROCAE ED-12 to airborne software. It connects software lifecycle evidence to the approval project. A motor-control application needs evidence appropriate to its allocated safety role; citing a software standard alone does not establish compliance or approval.
