RTCA published the document as RTCA/DO-178B, while EUROCAE published the document as ED-12B. Although technically a guideline , it was a de facto standard for developing avionics software systems until it was replaced in 2012 by DO-178C .
With application of DO-178B, it was discovered that many projects were not complying with DO-178B, but there was also wide variations in how various certification authorities conducted project assessments. In response, the CAST developed a standard software compliance assessment approach.
Diagram illustrating the required bidirectional tracing between certification artifacts, as required by the RTCA DO-178C standard. Thin blue-colored traces and blue-filled boxes are required only for Level A. Purple-colored traces and purple-filled boxes are required for Levels A, B, and C. Thick green-colored traces and green-filled boxes are ...
Many of RTCA documents begin with the letters DO which stands for DOcument. RTCA develops Minimum Operating Performance Standards for aviation-based technology (typically avionics) but has developed standards for such far-ranging topics as Airport Security, Counter UAS Detection standards, and Aircraft Cockpit and Cabin Cleaning standards.
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.
Some representative standards include MIL-STD-2167 for military systems, or RTCA DO-178B and its successor DO-178C for civil aircraft. The regulatory requirements for this software can be expensive compared to other software, but they are usually the minimum that is required to produce the necessary safety.
The DO-254/ED-80 standard is the counterpart to the well-established software standard RTCA DO-178C/EUROCAE ED-12C. With DO-254/ED-80, the certification authorities have indicated that avionics equipment contains both hardware and software, and each is critical to safe operation of aircraft.
ARP4754 is intended to be used in conjunction with the safety assessment process defined in SAE ARP4761 (updated to Revision A in December 2023) and is supported by other aviation standards such as RTCA DO-178C/DO-178B and DO-254. This guideline addresses Functional Safety and design assurance processes.
