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 Altitude Hold Mode is automatically armed when Vertical Speed Mode is selected.
Vertical Speed Mode does not consider the relative position of the Selected Altitude in relation to the current
aircraft altitude at the time of mode activation, so it is possible to use Vertical Speed Mode while not climbing/
descending to the Selected Altitude.
Vertical Speed Mode is activated by pressing the VS Key; the ‘VS’ annunciation appears in the AFCS Status
Box to indicate the active pitch mode, along with the Vertical Speed Reference to the right. The Vertical Speed
Reference is also displayed above or below the Vertical Speed Indicator, depending on whether the aircraft
is climbing or descending. A Vertical Speed Reference Bug corresponding to the Vertical Speed Reference is
shown on the indicator.
