Autopilot Operation
SkyView HDX Pilot’s User Guide – Revision B 8-17
All of the buttons in the above figure are explained briefly in the order they appear on the
AUTOPILOT control page in the Expert mode. The modes and functions controlled by each
button will be explained in greater detail in following sections.
AP
Engages and disengages the Autopilot servos.
FD
Activates and deactivates the flight director. When the autopilot servos are engaged, the flight
director is always activated.
YD
Pressing YD engages and disengages the yaw damper. Yaw damper normally engages when the
autopilot is engaged but can be controlled separately from roll and pitch servos with this
button. Button is not shown if the yaw servo is not installed.
HDG
Activates and deactivates the Heading mode for roll axis control.
HDG will be unavailable and grayed-out if the autopilot is outside of its allowable engagement
speed ranges.
TRK
Activates and deactivates the Track mode for roll axis control.
TRK will be unavailable and grayed-out if there is not a valid GPS signal or if the autopilot is
outside of its allowable engagement speed ranges.
ALT HOLD
Activates and deactivates the Altitude Hold mode for pitch axis control. Activation of this mode
commands the Autopilot to hold the current altitude immediately. Altitude hold is always
armed when activating VS or IAS modes so manual arming is not necessary.
ALT HOLD will be unavailable and grayed-out if the autopilot is outside of its allowable
engagement speed ranges.
VS
Activates and deactivates the Vertical Speed mode for pitch axis control during altitude
changes.
VS will be unavailable and grayed-out if the autopilot is outside of its allowable engagement
speed ranges.
