Overview System Instruments Flight EIS CNS Interface GPS Navigation Flight Planning Integrated Autopilot 4) G3X: From the PFD or PFD Page, press the VOR CRS Softkey (or press XPDR/CRS > VOR CRS if a transponder is configured) and turn the FMS Joystick to select the inbound approach course (radial). 5) G3X: From the PFD or PFD Page, press the HDG/ROLL Softkey to access the autopilot lateral modes and then press the AP NAV Softkey. If there is less than half-scale deviation when the AP NAV Softkey is pressed, VOR Mode will activate (green text), intercept, and track the selected radial. If there is more than half-scale deviation when the AP NAV Softkey is pressed, VOR Mode will arm (white text) first, then activate when closer to the radial. 6) Adjust the aircraft's pitch axis as required. LOCALIZER APPROACH (NO GS) LOC Mode is used to fly a localizer only approach (no glideslope). Selecting LOC Mode for a localizer only approach: 1) EXTERNAL NAVIGATOR: Tune and activate the desired LOC frequency, 2) G3X: Ensure that LOC1 is the selected navigation source (use the CDI SRC Softkey on the PFD or PFD Page to cycle through external navigation sources if necessary). The HSI should automatically slew the needle to the correct course. 3) G3X: From the PFD, press the HDG/ROLL Softkey to access the autopilot lateral modes and then press the AP NAV Softkey to activate LOC Mode. If the localizer deviation is less than half-scale when the AP NAV Softkey is pressed, the autopilot will activate LOC Mode and track the localizer, otherwise LOC Mode is armed and the pilot is responsible for intercepting the localizer. In some cases it may be necessary to use HDG Mode with LOC Mode armed to follow a vector to the localizer. BACKCOURSE APPROACH NOTE: When making a backcourse approach, set the Selected Course to the localizer front course. NOTE: 'BC' will not be displayed on the G3X HSI.

4)
G3X:
From the PFD or PFD Page, press the
VOR CRS
Softkey (
or press
XPDR/CRS
>
VOR CRS
if a transponder is configured) and turn the
FMS
Joystick to select the inbound approach course (radial).
5)
G3X:
From the PFD or PFD Page, press the
HDG/ROLL
Softkey to access
the autopilot lateral modes and then press the
AP NAV
Softkey.
If there
is less than half-scale deviation when the
AP NAV
Softkey is pressed, VOR
Mode will activate (green text), intercept, and track the selected radial.
If there is more than half-scale deviation when the
AP NAV
Softkey is
pressed, VOR Mode will arm (white text) first, then activate when closer to
the radial.
6)
Adjust the aircraft’s pitch axis as required.
LOCALIZER APPROACH (NO GS)
LOC Mode is used to fly a localizer only approach (no glideslope).
Selecting LOC Mode for a localizer only approach:
1)
EXTERNAL NAVIGATOR:
Tune and activate the desired LOC frequency,
2)
G3X:
Ensure that LOC1 is the selected navigation source (use the
CDI
SRC
Softkey on the PFD or PFD Page to cycle through external navigation
sources if necessary).
The HSI should automatically slew the needle to the
correct course.
3)
G3X:
From the PFD, press the
HDG/ROLL
Softkey to access the autopilot
lateral modes and then press the
AP NAV
Softkey to activate LOC Mode.
If the localizer deviation is less than half-scale when the
AP NAV
Softkey
is pressed, the autopilot will activate LOC Mode and track the localizer,
otherwise LOC Mode is armed and the pilot is responsible for intercepting
the localizer.
In some cases it may be necessary to use HDG Mode with
LOC Mode armed to follow a vector to the localizer.
BACKCOURSE APPROACH
NOTE:
When making a backcourse approach, set the Selected Course to the
localizer front course.
NOTE:
BC’ will not be displayed on the G3X HSI.
