ARP4761A Training: Aircraft & System Safety Training
SAE ARP4761 “Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment” describes guidelines and methods for performing safety assessments associated with showing compliance with aeronautics and space certification requirements of 14CFR/CS 2X.1309 and 33.75. Safety assessments are an essential part of aircraft/system development process. This ARP represents industry best practice and is formally recognized by numerous National Airworthiness Authorities (NAAs), Military Airworthiness Authorities (MAAs), FAA and EASA. The safety assessment process is of fundamental importance in establishing appropriate safety objectives and requirements for the aircraft and its systems, and in determining that the designs satisfy these objectives and requirements.
SAE ARP4761 safety assessments are described as an integral process in ARP4754A “Guidelines for Development of Civil Aircraft and Systems”. There are fundamental relationships between safety assessments and the system development processes.
This training provides attendees with the knowledge to understand and apply the safety assessments techniques, as well as understanding the interaction between safety processes and the overall aircraft or system development processes.
Although ARP 4761’s context is commercial aircraft, its techniques are also applicable to safety assessment of ground or space vehicles.
AFuzion’s training has been provided to over 23,000 aviation engineers from 1,000 companies in 30 countries; more than all other trainers in the world combined.
