Gps, Vor & Loc Modes - Garmin G3X Pilot's Manual

Integrated Autopilot
CHANGING THE SELECTED COURSE
The Selected Course is controlled by pressing the OBS CRS Softkey,
VOR CRS Softkey, or LOC CRS Softkey, (while in OBS, VOR, LOC, or BC
Mode) and turning the FMS Joystick on the G3X PFD (or PFD Page) to
select the desired course (or press XPDR/CRS > OBS CRS / VOR CRS
/ LOC CRS from the PFD (or PFD Page) if a transponder is configured).
Pressing the CWS Button (if equipped) and hand-flying the aircraft does
not change the Selected Course while in Navigation Mode. The Integrated
Autopilot guides the aircraft back to the Selected Course (or GPS flight
plan) when the CWS Button is released.
GPS, VOR & LOC MODES
NOTE: VOR, LOC, and GS modes are all GPS-aided. You must have a GPS
position and a valid navigation database to use VOR, LOC, or GS modes.
NOTE: When intercepting a flight plan leg, the Integrated Autopilot gives
commands to capture the active leg at approximately a 45º angle to track
between the waypoints defining the active leg. The Integrated Autopilot does
not give commands to fly to the starting waypoint of the active leg unless a
direct-to course to the first flight plan waypoint is entered.
Pressing the AP NAV Softkey acquires and tracks the selected navigation
source (GPS, VOR, LOC). The integrated autopilot follows GPS roll steering
commands when GPS is the selected navigation source. When the navigation
source is VOR or LOC, the autopilot creates roll steering commands from the
Selected Course and deviation. Navigation Mode can also be used to fly non-
precision GPS and LOC approaches where glideslope capture is not required.
If the Course Deviation Indicator (CDI) shows greater than one dot when
the AP NAV Softkey is pressed, the selected mode is armed. If the CDI is less
than one dot, Navigation Mode is automatically captured when the AP NAV
Softkey is pressed. The armed annunciation appears in white to the left of the
active lateral mode.
