ARP 4761 stands for Aerospace Recommended Practice 4761. It is a guideline for the safety assessment of aircraft and aircraft systems that is widely used in the aerospace industry.
The guideline was developed by the Society of Automotive Engineers (SAE) and provides a systematic approach for the identification, classification, and evaluation of hazards associated with aircraft and aircraft systems. ARP 4761 includes best practices for hazard analysis, risk assessment, risk mitigation, and verification and validation.
ARP 4761 is closely related to another guideline, ARP 4754, which provides guidance for the development of aircraft and aircraft systems. Together, these two guidelines provide a comprehensive approach to the development and certification of safe and reliable aircraft and aircraft systems.
ARP 4761 is widely used in the aerospace industry, particularly by manufacturers and suppliers of aircraft and aircraft systems. The guideline is also recognized by regulatory agencies such as the Federal Aviation Administration (FAA) and the European Aviation Safety Agency (EASA) as a standard for the safety assessment of aircraft and aircraft systems.
