The RTCA DO-278 / EUROCAE ED-109 "Guidelines for Communication, Navigation, Surveillance and Air Traffic Management (CNS/ATM) Systems Software Integrity Assurance" is a complementary standard to the airborne DO-178B standard. RTCA DO-278 / EUROCAE ED-109 provides guidelines for the assurance of software contained in non-airborne CNS/ATM systems.
The RTCA DO-278 / EUROCAE ED-109 guidelines are intended as a guide for the application of DO-178B guidance to non-airborne CNS/ATM systems. The two standards are therefore complementary and interrelated.
DO-278 provides guidelines for the production of software for ground based avionics systems and equipment that performs its intended function with a level of confidence in safety. The guidelines are in the form of:
The document discusses those aspects of certification that apply to the production of software for ground based avionics systems and are used in CNS or ATM equipment.
DO-278 Software Level Definitions are:
