But with the complexity of integration and function increasing in the system design process, the standard can not fully meets the state-of-art arp44754a requirements of designer and engineers.
DAL allocation pertaining to functional failure conditions and hazard severity are assigned to help mitigate risks. Revision A was released in December saf A significant new section is devoted to the process of determining Development Assurance Level DAL which determines the ar4p754a of complex hardware and software development and verification activities.
SAE ARP has been widely applied in the process of airworthiness certification in highly-integrated or complex electronic system of civil aircraft since Procedia Engineering Volume 17, Pages These are found in the U.
This page was last edited on 1 Juneat In order to better understand and apply ARP A in the field of airworthiness and safety, this paper will compare Sas 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.

This guideline addresses Functional Safety and design assurance processes. The focus was to be on safety assessment and fault-tolerant critical systems. This revision expands the design assurance concept for application at the aircraft and system level and standardizes on the use of the term development assurance.
Hence the new version SAE ARP A arises in Decemberwhich mainly revises the part of development assurance level 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.
