Autopilot

All of the autopilots approved for installation per this STC have a dedicated selection/setting on the
GI 275. Make the applicable selections for autopilots listed in this section (organized in the order of
display presentation). During the GI 275 system configuration, leave the GPSS Scaler to HDG set to the
default value. If unsure whether the Scaler to HDG is set to the default setting, all the settings can be reset
to default by selecting any other autopilot and then re-selecting the installed autopilot.
NOTE
Changing the Autopilot Interface setting will reset all autopilot settings to default.
CAUTION
Only the discrete outputs from the P2752 connector can be connected to the autopilot. The
discrete outputs on the main connector cannot be used.
The followings settings should only be configured on the GI 275 ADAHRS+AP that is directly connected
to a third-party autopilot. All other GI 275s in the system should select Other GI 275 as the autopilot
interface. If a GFC 600 is installed, all GI 275s in the system must be configured to GFC 600.
