Webto SAE ARP4761 Standard [3] its definition is “Fault Tree Analysis (FTA) is a deductive failure analysis which focuses on one particular undesired event and provides a method for determining causes of this event. In other words, a Fault Tree Analysis is a “top-down” system evaluation WebAn event tree is a graphical representation of fault progression, showing a time sequence of how an event develops. Event trees can be combined with fault trees and can reflect multiple possible outcomes (consequences), and they can be used predictively before incidents occur, or as part of incident investigation and analysis.
