Managing Major Zones

When you add a zone/major subs-zone to the zonal-L/HIRF hierarchy (for zonal lightning/high intensity radiated field (L/HIRF) analysis), you will be prompted to select from a predefined list. This ensures that the zonal analysis numbers used in each analysis comply with the numbering scheme established by the Airlines for America (A4A).

The software provides a predefined list of zones and major sub-zones that are based on the latest iSpec 2200: Aircraft Systems document published by the Airlines for America. Users with the "Manage all projects" permission have the ability to modify this list for the current database. Any changes to this master list will apply to all analysis projects in the same database.

To open the Manage Major Zones window, choose Home > Hierarchy Defaults > Manage Major Zones.

The left panel shows the list of top level items (called zones), while the right panel shows the list of second level items (called major sub-zones) that are associated with the currently selected top level item.

Each item is defined by an Zone # and a Description.

To edit the properties for an existing item, double-click the row or select the row and click the corresponding Edit button. To add a new item, click the Add button. To delete an existing item, select the row and press Delete or click the Delete button.

If you click the Set as default for future repositories button, the application will save the current list to the MPCDefaults.mpd9 file on your computer (C:\Users\uname\Documents\ReliaSoft\MPC9). Any future database that you create from this computer will use this saved customized list by default.
