Changing Cdi Sources - Garmin G500H Pilot's Manual

NOTE: The ILS Localizer and Glideslope deviation indicators will indicate
full-scale deflection for the GNS 480 navigator at the second dot. The GNS
400W/500W series navigators will indicate full-scale deflection at the edge
of the display.

Changing CDI Sources

The CDI can display two sources of navigation: GPS or NAV (VOR, and LOC).
Color indicates the current navigation source: magenta (for GPS) or green (for
VOR and LOC). The full-scale limits for the CDI are defined by a GPS-derived
distance when coupled to GPS. When coupled to a VOR or localizer (LOC), the
CDI has the same angular limits as a mechanical CDI. If the CDI exceeds the
maximum deviation on the scale (two dots) while coupled to GPS, the crosstrack
error (XTK) is displayed below the white aircraft symbol.
