ARP4761 and the Safety Assessment Process for Civil Airborne Systems
Duration: 2 Days

ARP4761 describes guidelines and methods for performing safety assessments. This recommended practice is associated with showing compliance with certification requirements (14CFR/CS Parts 23 and 25, section 1309) and assisting a company in meeting their own internal safety standards. The safety processes described are primarily associated with civil airborne equipment but the processes and tools may be applied to many applications.
This 2 day seminar provides attendees with the guideline information for conducting industry accepted safety assessments consisting of Functional Hazard Assessment (FHA), Preliminary System Safety Assessment (PSSA), and System Safety Assessment (SSA). Discussion on various safety analysis methods needed to conduct the safety assessments is included. Safety analysis methods including Fault Tree Analysis (FTA), Dependence Diagram (DD), Markov Analysis (MA), Failure Modes and Effect Analysis (FMEA) and Common Cause Analysis (CCA). CCA is composed of Zonal Safety Analysis (ZSA), Particular Risks Analysis (PRA), and Common Mode Analysis (CMA) and will be covered in this seminar.
In addition to the seminar handout, a copy of the ARP4761: Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment standard will be provided to each attendee.

Learning Objectives
By attending this seminar, you will be able to:

Identify multiple safety assessment methods and tools
Relate the key attributes of ARP4761 FHA, PSSA, SSA, FTA, DD, MA, CCA
Identify the applications for safety tools
Identify the interaction between the safety processes and the development processes
Apply multiple safety methods in completing a PSSA or SSA
Evaluate future tools and methods for inclusion in ARP4761A

Who Should Attend

This course is designed for engineers and professionals, working at all levels, who are involved in or interact with the aircraft and/or aircraft system safety assessment processes.

Prerequisites: None
