Vertical Speed Mode (Vs) - Garmin G3X Pilot's Manual

VERTICAL SPEED MODE (VS)

In Vertical Speed Mode, the flight director acquires and maintains a Vertical Speed
Reference. Current aircraft vertical speed (to the nearest 100 fpm) becomes the Vertical
Speed Reference at the moment of Vertical Speed Mode activation. This mode may be
used for climb or descent to the Selected Altitude (shown above the Altimeter) since
Selected Altitude Capture Mode is automatically armed when Vertical Speed Mode is
selected.
When Vertical Speed Mode is activated by pressing the VS Key (GMC 305) or AP VS
Softkey, 'VS' is annunciated in green in the Autopilot Status Box along with the Vertical
Speed Reference. The Vertical Speed Reference is also displayed above the Vertical
Speed Indicator. A Vertical Speed Reference Bug corresponding to the Vertical Speed
Reference is shown on the indicator.
CHANGING THE VERTICAL SPEED REFERENCE
The Vertical Speed Reference may be adjusted in the following ways:
• Use the NOSE UP/DN Wheel (GMC 305) or
down to adjust the Vertical Speed Reference in increments of 100 fpm. The
current Vertical Speed Reference is displayed in the G3X Autopilot Status
Box for 10 seconds after a change is made and as a
Vertical Speed Indicator
press ENT.
• Press the CWS Button (if equipped) and hand-fly the aircraft to a new
Vertical Speed Reference. When the CWS Button is released, the aircraft's
vertical speed (to the nearest 100 fpm) is established as the new Vertical
Speed Reference.
