ARP-4761 Training Program Overview
This comprehensive 2-day training provides an in-depth exploration of the ARP-4761 standard, the cornerstone of safety assessment processes in the aerospace industry. Designed for engineers, safety analysts, compliance officers, and project managers working on airborne systems, the course offers a structured journey through the complete aviation safety lifecycle — from initial hazard identification to advanced analysis and documentation practices.
Participants will gain a robust understanding of key safety assessment techniques, including Functional Hazard Assessment (FHA), Preliminary System Safety Assessment (PSSA), and System Safety Assessment (SSA). Through a balanced mix of theory, practical exercises, and real-world case studies, attendees will learn how to apply tools such as Fault Tree Analysis (FTA), Failure Modes and Effects Analysis (FMEA), and Common Cause Analysis (CCA) in line with ARP-4761 compliance expectations.
By the end of the training, attendees will be equipped with the knowledge and templates required to support the creation of safety documentation that aligns with certification requirements from regulatory bodies such as EASA and FAA. The course also emphasizes how to integrate safety workflows into ARP-4754A system development practices, enabling participants to contribute more effectively to cross-functional engineering teams.
Purpose of ARP 4761
- Identify safety risks during the design phase of aircraft systems,
- Define safety requirements for systems,
- Analyze system failures and their effects,
- Support safety processes compliant with other aviation standards (like DO-178, DO-254, SAE ARP 4754).
