Building the System Hierarchy

The items that you add to an MPC project for aircraft systems and powerplant analysis are arranged in a tree-based system configuration called the system hierarchy. To access the configuration, click the System Hierarchy tab on the System panel.

The System Hierarchy tab in MPC works in a manner similar to other ReliaSoft applications (such as Xfmea, RCM++ or RBI) except that there can be no more than four levels in the hierarchy (system, subsystem, sub-subsystem and part), and the first two levels must be selected from a predefined list of ATA chapters (systems) and sections (subsystems) that are stored in the database.

Each item has properties associated with it, which are viewed and edited on the Properties tab of the Analysis panel when the item is selected.

Available Columns

The following columns are displayed in the system hierarchy:

Note: If you select the Flag parts with "yes" answer(s) for MSI questions option on the Settings page of the Application Setup window, then the column will display a square icon, , for each part that has answered "Yes" to at least one MSI question. This makes it easier to see which parts may need extra attention.

Adding Systems and Subsystems

For compliance with the ATA numbering guidelines, the available system and subsystems have been predefined for the database. (Authorized users can modify the names and ATA numbers in the Manage ATA Chapters window.)

Both commands open windows that display the list of systems/subsystems that have been predefined for this database. Use the check boxes to select one or more items to add to the system configuration and click OK.

Note that each system/subsystem can be used only once per project. So if the item already exists in the current system configuration, the text will be grayed out and you will not be able to select it.

Adding Sub-subsystems and Parts

Sub-subsystems and parts are not predefined for the database. Instead, you have the flexibility to create these records as needed for your particular analysis.

Note the following:

Deleting

To delete an item from any MPC hierarchy, select the hierarchy item and press DELETE. The hierarchy item will be deleted, along with all dependents and all associated attachments. There is no undo for deleting an item or the entire hierarchy.

Cutting/Copying

You can cut or copy items in any MPC hierarchy and paste them to the same project or to another project within the same database. (Please note that if you want to share hierarchy items between different databases, you must use the import/export functionality instead.) To select multiple hierarchy items for cut or copy:

or

After you select the hierarchy items, you can use the standard keyboard shortcuts for cut/copy (CTRL+X and CTRL+C) or you can choose Home > Clipboard > Cut and Home > Clipboard > Copy. When a hierarchy item is cut or copied, all dependents will also be cut or copied, along with any attachments.

Pasting

To paste items that you have cut or copied from any MPC hierarchy, press CTRL+V or choose Home > Clipboard > Paste. Note the following:

Importing

It is easy to import any entire hierarchy (or selected items) from any project in the same database or another selected database. (See Importing MPC Hierarchies Between Projects.)
