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/DN Wheel
• Pressing the
CWS Button, hand-flying the aircraft to attain a new Vertical Speed Reference, then releasing
the CWS Button
