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 .

This task was published in the Federal Register at 61 FR Hence the new version SAE ARP A arises in December aep, which mainly revises the sae arp 4754 of development assurance sae arp 4754 allocation, provids a methodology to assign the correct development assurance levels.
Guidelines and methods for conducting the safety assessment process on civil airborne systems and equipment. Guidelines for Development of Civil Aircraft and Systems.
Retrieved from ” https: In order to better understand and apply ARP A in the field of qrp and safety, this paper will compare SAE ARP A and on aspects of applicable scope, development process and integral process, etc, expecting to make clear the differences and carry on analysis about the differences to show the significances of the changes for civil aircraft airworthiness and safety.
DAL allocation pertaining to functional failure conditions and hazard severity are assigned to help mitigate risks. Download full text in PDF Download.
A Comparison of SAE ARP A and ARP – ScienceDirect
A significant new section is devoted to sae arp 4754 process of determining Development Assurance Level DAL which determines the rigor of complex hardware and software development and verification activities. The Aerospace Recommended Practice 475 is a guideline for development of civil aircraft and systems with an emphasis on safety aspects.
But with the complexity of integration and function increasing in the system design process, the standard can not fully meets the sae arp 4754 technical requirements of designer and engineers.
