DO-254
DO-254, formally known as RTCA/DO-254 or EUROCAE/ED-80, is an international standard for the design assurance of airborne electronic hardware (AEH) in civil aircraft. It provides guidelines and processes to ensure that complex electronic hardware, such as FPGAs, ASICs, and custom microprocessors, meets safety and reliability requirements throughout its lifecycle. The standard is mandated by aviation authorities like the FAA and EASA for certification of commercial aircraft systems.
Developers should learn and use DO-254 when working on safety-critical avionics hardware projects, such as flight control systems, navigation equipment, or engine controllers, where failure could lead to catastrophic outcomes. It is essential for ensuring compliance with aviation regulations, reducing risks through rigorous verification and validation processes, and facilitating certification by demonstrating that hardware meets stringent airworthiness standards.
