FAQs

The main objective is to guide aviation safety professionals through a systematic process of identifying and classifying potential functional failures in aircraft systems, as required by the SAE ARP4761 standard.

The FHA checklist should be used early in the aircraft development process, typically during the conceptual and preliminary design phases, and updated throughout the development lifecycle.

By ensuring a comprehensive FHA is conducted, this checklist helps generate essential safety data required for aircraft certification, demonstrating compliance with safety regulations and standards.

Yes, the FHA checklist can be applied to both new aircraft designs and modifications to existing aircraft, helping assess the safety impact of functional changes or additions.

The FHA checklist is a crucial first step in the safety assessment process, providing inputs for subsequent analyses such as Preliminary System Safety Assessment (PSSA) and System Safety Assessment (SSA).
