5 TROUBLESHOOTING
This section provides instructions and guidance for G1000 system troubleshooting, as installed in the
King Air 300/B300.
IMPORTANT!
Sections 6, 7 and 8 provide detailed instructions on equipment removal,
replacement, configuration, and return-to-service testing. Anytime a G1000
component or LRU is removed, swapped, or replaced, the technician must follow
the procedures given in Sections 6, 7 and 8 to ensure proper operation of the system.
Troubleshoot the G1000 system by first identifying, then isolating the specific failure to the responsible
LRU. There are several indications that the G1000 presents to the pilot or technician, showing overall
system condition. A course of action should be determined based on the information presented on the
display. This section shows possible scenarios likely to be encountered during normal operation and
gives troubleshooting guidance to the technician to resolve problems.
Figure 5-1, AUX – System Status Page
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 can not communicate
with the LRU.
•
Serial Number: Each LRU serial number is displayed (functions such as GPS 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.
