If aGTN 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 CDIKey.3) G3X Touch: Ensure that VOR1 or VOR2 is the selected navigation source. Itshould 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 SyncCourse.5) G3X Touch: From the PFD, touch the autopilot and touch NAV.Or: Press the NAV Key on the GMC 305.If there is less than half-scale deviation when NAV is touched or the NAV Key ispressed, 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 GUIDANCENOTE: The selected navigation receiver must have a valid VOR or LOC signalor 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 GPSreception, a valid navigation database, and the external navigation receivermust have a valid signal (VOR or LOC).Touch NAV or press the NAV Key (GMC 305) to arm/activate VOR, LOC/BC,and GPS (LNAV only) lateral modes. Lateral modes acquire and track the selectednavigation source (GPS, VOR, or LOC), depending on the loaded approach. Thesemodes use the selected navigation receiver deviation and desired course inputs to flythe approach. Touch NAV when the CDI is greater than one dot to arm the selectedmodes (annunciated in white). Touch NAV when the CDI deviation is less than onedot to activate, capture and track the selected navigation source (GPS, VOR, or LOC).
