• You can use Fault Tree CCF Groups files to store CCFs (common cause failures) to copy them into any fault tree. A CCF is an event or mechanism that can cause two or more failures (basic events) to occur simultaneously.

• You can use repeated events, which are basic events that you insert in more than one place in the fault tree. When a repeated event occurs, it occurs simultaneously everywhere you have inserted it.

• You can use Fault Tree Event Library files to store commonly used events so that these events, and their failure and repair parameters, can easily be copied into any fault tree.

• You can run exact calculations. Or, you can run cut set approximations to expedite the analysis of large trees.

• You can customize the appearance of gates and events, including colors, fonts, images, and sizing.

• You can define very long descriptions for your gates and events and have the size of the figures automatically increased to fit the text.

• You can link fault tree events to other modules. If the linked data changes, these changes are automatically reflected within the fault tree. You can link FTA events to data in the following modules: FMEA, Markov, and Prediction.

• You can use Windchill FTA automatic paging to better manage large fault trees.

• In addition to standard time dependent fault trees, you can build and evaluate lambda tau and SAE ARP4754A and ARP4761 fault trees. You can also import CAFTA files into Windchill FTA.

• You can use Windchill Event Tree when you have a Windchill FTA license. The Event Tree module provides full event tree analysis capabilities. This means that you can analyze the consequences that result from a sequence of events occurring in your system.
