FHAs
FHAs, short for Functional Hazard Analyses, are a class of hazard analysis techniques used in safety engineering to identify and assess hazards associated with the functions of a system. They are commonly applied to safety-critical domains such as aerospace, automotive safety systems, and rail transportation, and are described in standards such as SAE ARP 4761. In these contexts, an FHA aims to determine which system functions could fail in a way that jeopardizes safety, and to classify the associated hazards by severity and risk.
The FHA process typically starts with a structured description of the system and its functions. For each
Limitations and scope: FHAs are most effective when conducted early in the design life cycle and updated
