What is DO-254 and when is it applied?

• A. DO-254 is a hardware assurance standard for airborne electronic hardware; applied to certify complex hardware components and boards.
• B. DO-254 is a software development framework for flight control software.
• C. DO-254 is a mechanical design standard for aircraft structures.
• D. DO-254 is a safety regulation for airline operations.

Answer: (A)

DO-254 is the hardware assurance standard used for airborne electronic hardware. It applies when certifying complex hardware components and boards that contain programmable elements, such as FPGAs, ASICs, and processors, which are part of safety-critical avionics. The standard guides the hardware development lifecycle and the evidence needed to show the hardware performs correctly and reliably in the intended environment. It uses design assurance levels to tailor activities for different levels of risk and requires thorough planning, requirements accuracy, design and implementation rigor, verification and validation, and robust configuration management and tool qualification. It’s the hardware counterpart to DO-178C for software, providing a structured approach to development and certification evidence for electronic hardware. It is not a mechanical design standard, nor a safety regulation for airline operations, and it isn’t for software development itself.
