SAE ARP has been widely applied in the process of airworthiness certification in highly-integrated or complex electronic system of civil aircraft since Starts with the FHA failure condition severity classification. • ARP A provides a development assurance level assignment process. – Function Development. So SAE ARP and SAE ARP go hand in hand and use functional approach to safety. Both ARPS focused on complex aircraft systems development .

Hence the new version SAE ARP A arises in Decembersae arp 4754 mainly revises the part of development assurance level allocation, provids a methodology to assign the correct development assurance levels. Retrieved from ” https: A significant new section is devoted to the process of determining Development Assurance Level DAL which determines the rigor of complex hardware and software development and verification activities.
Guidelines for Development of Civil Aircraft and Systems. This revision expands the design assurance concept for application at the aircraft and aae level and standardizes on the use of the term development assurance. Revision A was released in December The focus was to be on sae arp 4754 assessment and fault-tolerant critical systems.
