Vertical Speed Indicator (Vsi); Vertical Deviation Indicator And Vnav Indicator - Garmin G3X Pilot's Manual

VERTICAL SPEED INDICATOR (VSI)

The Vertical Speed Indicator displays the aircraft vertical speed using a non-moving
tape labeled at 500, 1000 and 2000 fpm with minor tick marks every 100 feet up to
1000 fpm. The current vertical speed is displayed using a white arrow along the tape.

VERTICAL DEVIATION INDICATOR AND VNAV INDICATOR

NOTE: An external navigator (i.e., SL30 Nav/Comm Transceiver and/or the GTN
or GNS Series Units) must be configured to receive glideslope and/or glidepath
vertical deviation indications.
GLIDESLOPE - ILS SOURCE
The Vertical Deviation (Glideslope) Indicator (VDI) appears to the left of the altimeter
whenever an ILS frequency is tuned in the active NAV field of an external navigator.
A green diamond acts as the VDI Indicator, like a glideslope needle on a conventional
indicator. If a localizer frequency is tuned and there is no glideslope signal, "NO GS"
is annunciated.
