The
Aux
– System Status
page displays the following information for each LRU and sub-
function:
•
Status: A green check is displayed for properly operating LRUs. A red ‘x’ appears when
an internal LRU fault is detected and it has taken itself offline, or if the MFD cannot
communicate with the LRU.
•
Serial Number: Each LRU serial number is displayed (functions such as COM and GS
are contained within an LRU; therefore, serial numbers are not shown for these).
•
Current SW Version Loaded.
When troubleshooting, first check to ensure that each LRU status is ‘green’ and that the correct
software is loaded in each unit. Additional airframe and database information is also displayed
on this page.
5.1 System Annunciations
If data fields become invalid due to an LRU failure, the PFD/MFD typically annunciates the
failure with a large red X, as shown in Figure 5-2.
