Encyclopedia
ARP4761, Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment is a standard (actually a Recommended Practice) from the Society of Automotive Engineers (SAE). In conjunction with SAE ARP4754
, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration
(FAA) airworthiness
regulations for transport category
aircraft
, and also harmonized international airworthiness regulations such as European Aviation Safety Agency
(EASA) CS–25.1309.
This Recommended Practice defines a process for using common modeling techniques to
assess the safety of a system being put together. The first 30 pages of the
document covers that process. The next 140 pages give an overview of the
modeling techniques and how they should be applied. The last 160 pages give
an example of the process in action.
Some of the methods covered:
In 2004, SAE began working on Revision A to ARP4761. When released, EUROCAE plans to jointly issue the document as ED–135.

Airworthiness
Airworthiness is a term used to describe whether an aircraft has been certified as suitable for safe flight. Certification is initially conferred by a Certificate of Airworthiness from a National Airworthiness Authority, and is maintained by performing required maintenance actions by a licensed...

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

European Aviation Safety Agency
The European Aviation Safety Agency is an agency of the European Union with offices in Cologne, Germany, which has been given regulatory and executive tasks in the field of civilian aviation safety. It was created on 15 July 2002, and it reached full functionality in 2008, taking over functions...

- Functional Hazard AssessmentHazard analysisA hazard analysis is used as the first step in a process used to assess risk. The result of a hazard analysis is the identification of risks. Preliminary risk levels can be provided in the hazard analysis. The validation, more precise prediction and acceptance of risk is determined in the Risk...
