3.7 Configuration Mode Overview
The Configuration Mode exists to provide the avionics technician with a means of configuring, checking,
and calibrating various G1000 sub-systems. Troubleshooting and diagnostics information can also be
viewed in this mode.
To start the system in Configuration Mode:
1. Apply external power, then set the BAT, EXT PWR and AVIONICS MASTER PWR switches to
ON.
2. Pull the MFD, PFD1 (PRI), PFD1 (SEC) and PFD2 circuit breakers.
3. Press and hold the ENT key on the co-pilot’s PFD while applying power using the PFD 2 circuit
breaker.
4. Release the ENT key after ‘INITIALIZING SYSTEM’ appears in the upper left corner of the
PFD.
5. Press the ENT key or the YES softkey to update system files if prompted.
6. Repeat steps 1 through 3 on the MFD using the MFD circuit breaker to apply power and using the
far right soft key on the MFD or the ENT key on the GCU 475 FMS controller where called out
in Steps 1 through 3. (Note that the ENT key for the MFD is located on the GCU 475 FMS
controller and will not function prior to software load.)
7. Repeat steps 1 through 3 on the pilot’s PFD using the PFD 1 (PRI) and PFD 1 (SEC) circuit
breakers to apply power.
CAUTION:
The Configuration Mode contains certain pages and settings that are critical to aircraft
operation and safety. These pages are protected and cannot be modified, unless the
technician is properly authorized and equipped. However, most protected pages are
viewable to allow system awareness for troubleshooting.
NOTE
If the specific procedure requires an SD card to be in the top slot of the PFD/MFD, this
card must be inserted prior to applying power to the PFD/MFD. Any time a card is
inserted, the power to the PFD/MFD must be cycled.
NOTE
For a complete description and breakdown of each Configuration Mode page, refer to the
G1000 System Maintenance Manual listed in Table 1-2.
