2. System safety - Wikipedia

   en.wikipedia.org/wiki/System_safety

   The system safety concept calls for a risk management strategy based on identification, analysis of hazards and application of remedial controls using a systems-based approach. [1] This is different from traditional safety strategies which rely on control of conditions and causes of an accident based either on the epidemiological analysis or as ...

3. ARP4761 - Wikipedia

   en.wikipedia.org/wiki/ARP4761

   The Functional Safety process is focused on identifying functional failure conditions leading to hazards. Functional Hazard Analyses / Assessments are central to determining hazards. FHA is performed early in aircraft design, first as an Aircraft Functional Hazard Analysis (AFHA) and then as a System Functional Hazard Analysis (SFHA).

4. DO-178B - Wikipedia

   en.wikipedia.org/wiki/DO-178B

   The system safety assessments combined with methods such as SAE ARP 4754A determine the after mitigation DAL and may allow reduction of the DO-178B software level objectives to be satisfied if redundancy, design safety features and other architectural forms of hazard mitigation are in requirements driven by the safety analyses. Therefore, DO ...

5. Hazard analysis - Wikipedia

   en.wikipedia.org/wiki/Hazard_analysis

   ANSI/GEIA-STD-0010-2009 (Standard Best Practices for System Safety Program Development and Execution) is a demilitarized commercial best practice that uses proven holistic, comprehensive and tailored approaches for hazard prevention, elimination and control. It is centered around the hazard analysis and functional based safety process.

6. Layers of protection analysis - Wikipedia

   en.wikipedia.org/wiki/Layers_of_protection_analysis

   Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. . In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and event trees.

7. DO-178C - Wikipedia

   en.wikipedia.org/wiki/DO-178C

   The Software Level, also known as the Development Assurance Level (DAL) or Item Development Assurance Level (IDAL) as defined in ARP4754 (DO-178C only mentions IDAL as synonymous with Software Level [10]), is determined from the safety assessment process and hazard analysis by examining the effects of a failure condition in the system. The ...

8. ARP4754 - Wikipedia

   en.wikipedia.org/wiki/ARP4754

   ARP4754(), Aerospace Recommended Practice (ARP) Guidelines for Development of Civil Aircraft and Systems, is a published standard from SAE International, dealing with the development processes which support certification of Aircraft systems, addressing "the complete aircraft development cycle, from systems requirements through systems verification."

9. Fault tree analysis - Wikipedia

   en.wikipedia.org/wiki/Fault_tree_analysis

   A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
