Figure 4 shows the QFO-C FCD Menu Tree. The MODE command toggles among the selections on the current menu level. For example, if the FCD is
displaying QFO-C ÒSTAT MAJ ALRMÓ (Figure 4, Level 1) and the MODE command is issued, the ÒVIEWÓ menu displays. If the MODE command is issued again, the ÒPROVÓ menu displays, etc.
The SELECT command selects a menu element and descends the menu to the next level. For example, if the FCD is displaying QFO-C ÒALRM PROVÓ (Figure 4, Level 1) and the SELECT command is issued, the ÒESÓ sub-menu displays. If the SELECT command is issued again, the Ò15 MIN ERR THLDÓ sub-menu displays, etc. If a read/write element is selected, the display prompts the user to save the setting. The message ÒSAVEÓ flashes on the display followed by the message ÒNO.Ó If the user wishes to go back to the original setting, press the MODE/ SELECT switch to SELECT. If the user wishes to choose the new setting, press the MODE/SELECT switch to MODE. The message ÒYESÓ displays. Press the MODE/SELECT switch to SELECT to have the new setting take effect. After selecting the new setting, the display returns to flashing between the option name and the current setting for that option. The MODE switch can then be used to scroll through the remaining options.
The ESCAPE command ascends the menu tree. Issuing an ESCAPE command on any menu item ascends the menu one level and displays the first element on that level. For example, if the FCD is displaying QFO-C Ò20 MINÓ on level 3 of Figure 4 and the ESCAPE command is issued, the ÒLB TOUTÓ menu displays. If the element is a read/write value, it maintains its original value.
The ROOT command ascends to the first element of the Level 1 card menu. If the ROOT command is issued from any non-level 1 location, the menu displayed is the first element of level 1. For the QFO-C Menu Tree (Figure 4), the FCD displays QFO-C ÒSTATÓ (first element of Level 1). If the ROOT command is issued from a level 1 location, the software interprets the ROOT command as an ESCAPE command and displays the SCU menus.
