ARP 4761 is a key guideline for safety assessments of civil airborne systems to meet certification requirements for new designs and modifications. In conjunction with its companion standard ARP4754, ARP4761 provides a comprehensive framework for achieving acceptable level of risk.
Implementation of ARP4754 and ARP4761 mandates adoption of systematic management of requirements and traceability management at different levels of design with a clear concise Safety Program Plan.
