SAE International, dealing arp 4754 pdf download the development processes which support certification of Aircraft systems. Revision A is a substantial rewrite of the document which describes the safety process as a part of an Integrated Development Process.
This guideline addresses Functional Safety and design assurance processes. DAL allocation pertaining to functional failure conditions and hazard severity are assigned to help mitigate risks. Assessments are central to determining hazards and assigning DAL, in addition to requirements based testing and other verification methods. ARP4754 was defined in the context of aircraft certification, in particular Part 25 Sections 1301 and 1309 of harmonized civil aviation regulations for transport category airplanes.
These are found in the U. 1309, AC 1309-1A, and related documents, and to consider revision to AC 1309-1A incorporating recent practice, increasing complex integration between aircraft functions and the systems that implement them, and the implications of new technology. In a parallel effort, SAE published ARP4754 in November 1996. This draft remains unreleased, but ARP4754 became broadly recognized as an appropriate standard for aircraft system development and certification. 79 as valid for certification of other aircraft categories, and for specific systems such as avionic databuses. ARP4754A and ED79A were released by SAE and EUROCAE in December 2010. The document title has changed to Guidelines For Development Of Civil Aircraft and Systems.
