IMPORTANT!
If the technician is unsure of an aircraft’s STC Configuration, perform the
following steps:
1. Inspect the aircraft maintenance logs for records of which STC configuration is installed. Inspect
aircraft records for signs of other alterations, including field updates and Service Bulletins.
2. Power on the G1000 system by setting the BAT switch to ON, then the EXT PWR switch to ON and
finally the AVIONICS MASTER switch to ON.
3. Following MFD power-up, observe upper right section of MFD splash screen for airframe
configuration.
OR
After acknowledgement of the splash screen, use the FMS knob on the GCU 475 controller to go to
the AUX – SYSTEM STATUS page on the MFD. In the AIRFRAME section (upper right corner,)
the display shows the current G1000 airframe configuration and system software version number.
The airframe configuration is shown in the AIRFRAME field and the system software version
number is shown in the following format: ‘System Software Version XXXX.XX’. It correlates to the
G1000 software used to load the software to the system:
EXAMPLE:
System Software Version ‘0636.02’ = G1000 Software P/N 006-B0636-02
The G1000/GFC 700 C90 General Arrangement Drawing, Garmin Document 005-00375-22, defines
