FTA Severities

On the left side of the screen, the user can create new Severities that can be associated to the failure conditions. The severities are linked to a project (all systems in it). There are two fields in the form:

  • Criticality: In the context of aerospace and following the ARP4761 standard, this field categorizes the failure condition’s impact level. Options include “Catastrophic,” “Hazardous,” “Major,” and so on, as per the standard guidelines.

  • Target Probability: This specifies the maximum allowable likelihood of the associated failure condition occurring. It is generally set to align with the defined Criticality level.

FTA Report settings

On the right side of the screen, the user can define the different settings related to each system.

By selecting the desired system in the top-left dropdown, the user can customize various properties that will be reflected in the PDF report. These properties include the logo, the copyright text, colors for different types of nodes, and the display precision for decimal numbers.

The specified decimal precision applies exclusively to reports for FTA Diagrams, Minimal Cutsets, and Basic Events, leaving the interface unaffected.
