6. This ‘System’ number is the System Software Version. It correlates to the G1000
SW Loader Card used to load the software to the system:
EXAMPLE:
System Software Version ‘
0670.03
’ = Loader Card P/N 010-0
0670-03
7. Verify that the System Software Version is correct.
8. Press the ENT key to acknowledge the agreement on the MFD (the rightmost
softkey may also be used to acknowledge the agreement).
NOTE
In the normal operating mode, data fields that are invalid have large red
X’s through them. A valid field does not display a red X.
9. Allow the displays to initialize for approximately one minute. The GDC 74A and
GRS 77/GMU 44 require a longer initialization period than do other LRUs.
During normal operation, this causes the attitude, heading, airspeed, altitude,
vertical speed, and OAT fields to be invalid during the first 40-60 seconds of PFD
power-up.
10. Verify that no ‘Manifest’ errors appear when the ALERTS softkey is pressed.
11. Check that all COM/NAV fields are valid in the top corners of the PFD and MFD.
12. Check that attitude, heading, altitude, airspeed, vertical speed, TAS, and OAT
fields are valid on the PFD.
13. Verify that there are no BACKUP PATH alerts on the PFD. If an LRU is not
communicating over its primary path, the BACKUP PATH alert will identify which
LRU is having the problem. Correct the problem before proceeding; refer to the
G1000 System Maintenance Manual (190-00907-00) as needed.
14. Verify that engine and airframe instruments are valid on the MFD.
15. Push the red DISPLAY BACKUP button on the GMA 1347. Verify both displays
enter reversion mode: both should have valid attitude, altitude, airspeed, vertical
speed, and engine instruments.
16. De-activate reversion mode by pushing the DISPLAY BACKUP button again.
