Auto-Slewing - Garmin G500 Pilot's Manual

The vertical deviation is similar to the glideslope for GPS approaches
supporting WAAS vertical guidance (LNAV+V, L/VNAV, LPV, LP+V). When
an approach of this type is loaded into the flight plan and GPS is the selected
navigation source, the Vertical Deviation Indicator appears as a magenta
diamond. If the approach type downgrades to LNAV past the final approach fix
(FAF), or the approach only supports LNAV service, "NO GP" is annunciated.

Auto-Slewing

The G500/G600 system is designed to interface with GPS navigator units
and also manage up to four different CDI course pointers (GPS1, NAV1, GPS2,
NAV2) independently. The G500/G600 will automatically slew the NAV course
pointer to the correct final approach course when a ILS, LOC, LOC BC, LDA or
SDF approach is active in the GPS navigator and the appropriate frequency is
in the active window in the navigator. The G500/G600 will Auto-Slew the HSI
course pointer for an ILS, LOC, LOC BC, LDA, or SDF approach when the steps
below are completed in the following order:
1. The desired approach is selected and activated in the navigator (this can be
verified by the approach waypoints appearing on the GDU 620 MFD Nav Map
Page or FPL Page).
2. The appropriate frequency is the active frequency in the navigator.
3. The CDI selection on the GDU 620 is changed to NAV course pointer for the
active navigator.
