• Flight Controls – used to configure the system for Garmin and Non-Garmin autopilots if installed.
• Backlight – used to configure backlight configuration parameters.
• Display – used to configure the display format of the G5.
• Battery – used to set backup battery status and power off modes.
• GPS – used to configure the internal GPS receiver.
• Navigation – used to configure the display of navigation information
• Units – This page is used to configure the units type to display altitude, airspeed, ground speed,
vertical speed and pressure displays.
• RS-232 – used to configure the RS-232 input and output ports used of the G5.
• ARINC 429 - used to configure the ARINC 429 input and output ports used of the G5.
• Exit Configuration Mode – used to exit configuration mode.
7.4.2 G5 Configuration
Before replacing a G5 unit, the technician should obtain the most current G5 configuration settings
which are typically kept with the aircraft records (reference APPENDIX A ). If the existing
configuration setting record is not available, set the configuration to match the values and units indicated
in the aircraft’s AFM or other operational information. If any changes are made to the configuration
settings, record the new settings in APPENDIX A and keep in the aircraft records for future reference.

7.5.1 Calibration Procedure A: Pitch/Roll Offset Compensation
NOTE
If two G5’s are installed, this procedure must be done on both and can be done concurrently.
See Section 7.5.1.1 for example of this calibration procedure.
Using the following procedure, complete these equations.
