The plan for designing the airborne electronic hardware: the design process, methods, standards, tools, reviews, transition criteria and the data to be produced at each stage.
Plan Work product in the Avionics and airborne electronics lifecycle
DO-254 expects the design process to be planned before it starts, and the authority reviews the plan. It feeds the plan for hardware aspects of certification, verification planning and process assurance; without it, design proceeds without agreed criteria and later evidence does not match what the authority expects.
