Intercepting and tracking a VOR radial:
1)
EXTERNAL NAVIGATOR: Tune and activate the desired VOR frequency.
If a
GTN or GNS series unit is not configured skip to Step 3.
2)
EXTERNAL NAVIGATOR (GTN or GNS series units only): Ensure the ‘VLOC’
indication is showing in the lower-left corner of the
. If not, press the CDI
Key.
3)
G3X Touch: Ensure that VOR1 or VOR2 is the selected navigation source. It
should say ‘VOR1’ or ‘VOR2’ on the HSI and the needle should be green.
4)
G3X Touch: From the PFD, touch the course on the PFD and touch Sync
Course.
5)
G3X Touch: From the PFD, touch the autopilot and touch NAV.
Or
:
Press the NAV Key on the GMC control unit.
If there is less than half-scale deviation when NAV is touched or the NAV Key is
pressed, VOR Mode will activate (green text), intercept, and track the selected radial.
If there is more than half-scale deviation when NAV is touched, VOR Mode will arm
(white text) first, then activate when closer to the radial.
APPROACHES WITHOUT VERTICAL GUIDANCE
NOTE: The selected navigation receiver must have a valid VOR or LOC signal
or active GPS course for the flight director to enter Approach Mode.
NOTE: For the autopilot to enter a VLOC mode, the G3X Touch must have GPS
reception, a valid navigation database, and the external navigation receiver
must have a valid signal (VOR or LOC).
Touch
NAV
or press the NAV Key (GMC control unit) to arm/activate VOR, LOC/
BC, and GPS (LNAV only) lateral modes. Lateral modes acquire and track the selected
navigation source (GPS, VOR, or LOC), depending on the loaded approach. These
modes use the selected navigation receiver deviation and desired course inputs to fly
the approach. Touch
NAV
when the CDI is greater than one dot to arm the selected
modes (annunciated in white). Touch
NAV
when the CDI deviation is less than one
dot to activate, capture and track the selected navigation source (GPS, VOR, or LOC).
