ABSTRACT
DO-254 development takes place within the context of ARP4754 processes. The certification aspects of airborne electronic hardware are encapsulated by the development of the system in which the electronic hardware is used. Similarly, the system development is performed within the context of a certification program for an aircraft, a modification or update to an aircraft, or in the case of a technical standard order (TSO), the TSO approval process. The system and safety processes start before, or along with, the DO-254 planning processes. The system process outputs that factor into planning include: system description and hardware description. Project planning begins with a combination of several aspects—the idea for the design, gathering the processes and tools to accomplish the design, establishing the resources and organization to accomplish the tasks, evaluating customer-specific requirements, and evaluating project-specific aspects including the certification basis. Verification standards describe the criteria for the verification activities including review, analysis, and test.
