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 must have GPS
reception, a valid navigation database, and the external navigation receiver
must have a valid signal (VOR or LOC).
Press the
AP NAV
Softkey or
NAV
Key (GMC 305) 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. Press the
AP NAV
Softkey when the CDI is greater than one dot to
arm the selected modes (annunciated in white). Press the
AP NAV
Softkey when the
CDI deviation is less than one dot to activate, capture and track the selected navigation
source (GPS, VOR, or LOC).
