Vertical Command Control
Using the same cyclic switch as
mentioned in the previous para-
graph, vertical commands can be
modified by moving the vertical com-
mand switch fore and aft. Operation
of the Vertical Command Control
depends on the flight director or
autopilot mode engaged. Moving
the switch forward adjusts the heli-
copter’s pitch attitude downward,
while moving it rearward adjusts the
attitude upward.
Activating Vertical Command
cancels certain flight director vertical
tracking modes, but has no effect on
modes engaged in the Arm phase.
The flight director will revert to Pitch
Attitude Hold if it was coupled in
Glideslope, Altitude Capture or Go-
Around at the moment of command
activation. Attitude Hold, Altitude
Hold, Indicated Airspeed Hold and
Vertical Speed Hold will remain cou-
pled throughout Vertical Command
operation.
