SAE AIR7209

The purpose of this SAE Aerospace Information Report (AIR) is to provide a high-level set of principles to support aerospace projects required to use a formal development assurance process, such as ARP4754/ED-79 (at latest revision), to show regulatory compliance. Examples of projects where a formal development assurance process is needed are those that have significant functional interactions or whose products cannot be fully analyzed or tested. Development assurance techniques reduce the likelihood of undetected errors that could have safety impacts in the operation of the product. Design and analysis techniques traditionally applied to deterministic risks or to conventional, non-complex systems may not provide adequate safety coverage for more complex systems. This document does not mandate specific processes to meet each development assurance principle. These principles are written at a high level to allow flexibility so that users can develop and evaluate their own compliant development assurance processes. Users are responsible for presenting their development assurance approach to certification authorities and obtaining agreement. The framework in this document can assist with this coordination. This SAE Aerospace Information Report (AIR) provides a high-level set of principles for the development assurance of aerospace vehicles and systems, including emerging technologies. The principles are meant to address experience of applying ARP4754/ED-79 (at latest revision) across a variety of applications. This document is technically identical to ER-023. If further elaboration of specific technologies is determined to be required, additional AIRs/ERs may be created.
