Vertical Speed Mode (Vs) - Garmin G900X Pilot's Manual

AUTOMATIC FLIGHT CONTROL SYSTEM

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, 'VS' is annunciated in green in the AFCS 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 (shown both in the AFCS Status Box and above the Vertical Speed Indicator)
may be changed by:
• Using the NOSE UP/NOSE DN Keys
• Pressing the CWS Button, hand-flying the aircraft to attain a new Vertical Speed Reference, then releasing
the CWS Button
