Non-Garmin Autopilots - Garmin G3X Touch Pilot's Manual

AFCS
NOTE: Check step #5 if the external navigator doesn't automatically switch
from GPS to VLOC Mode shortly after turning inbound on the final approach
course.
LEVEL MODE
Level Mode is coupled in pitch and roll modes and is annunciated as both the vertical
and lateral modes when active. Pressing the LVL Key engages the autopilot in Level
vertical and lateral modes. Level Mode does not track altitude or heading. When the
LVL Key is pressed all armed and active modes are canceled and the autopilot and
flight director revert to LVL mode for pitch and roll. While in level mode, all other
modes are available by pressing the corresponding button.

9.4 NON-GARMIN AUTOPILOTS

When interfacing the G3X Touch with a non-Garmin autopilot, the following applies:
• The PFD can be used to select 'Course' and 'Heading' for non-Garmin autopilots.
• G3X Touch cannot support NAV source selection between two external navigators
for a non-Garmin autopilot, therefore installations with a non-Garmin autopilot
are limited to one external navigator interface.
• The PFD supports GPS Steering (GPSS) mode which converts GPS roll steering
commands into heading commands for non-Garmin autopilots that lack a GPS
Navigation interface. GPSS mode is selected/deselected directly on the PFD.
Either the internal G3X Touch flight plan can be used or the external flight plan
from a compatible Garmin navigator. While GPSS mode is active on the G3X
Touch PFD, the pilot must select 'GPS' as the active NAV source and 'Heading'
mode on the non-Garmin autopilot.
