This SAE Aerospace Information Report will be a compilation of system safety engineering and management terms and definitions covering concepts used across multiple products and disciplines

Provides standard guidance on major tasks and activities and how to implement and manage Functional Safety and software system safety aspects of Model Based System Engineering (MBSE). Process focus is on safety-critical functions (SCF) of complex software intensive systems being modeled and depicted graphically as part of MBSE and software engineering to ensure safety engineering aspects are tracked and captured as part of models to enhance safety documentation and produce objective safety evidence.

This document outlines a standard practice for conducting system safety. In some cases, these principles may be captured in other standards that apply to specific commodities such as commercial aircraft and automobiles. For example, those manufacturers that produce commercial aircraft should use SAE ARP4754 or SAE ARP4761 (see Section 2 below) to meet FAA or other regulatory agency system safety-related requirements. The system safety practice as defined herein provides a consistent means of evaluating identified risks. Mishap risk should be identified, evaluated, and mitigated to a level as low as reasonably practicable. The mishap risk should be accepted by the appropriate authority and comply with federal (and state, where applicable) laws and regulations, executive orders, treaties, and agreements. Program trade studies associated with mitigating mishap risk should consider total life cycle cost in any decision.
