System Overview Flight Instruments EIS CNS Interface GPS Navigation Flight Planning 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 nonprecision 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.

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.
