ALT HOLD
Activates / Deactivates altitude hold mode. 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.
VNAV
Arms / disarms vertical navigation mode. If not already active, also activates altitude hold
mode.
VNAV will be unavailable and grayed-out if the autopilot is outside of its allowable engagement
speed ranges. VNAV can be armed before a valid glide slope indication has been established to
allow GPS to ILS transitions to be armed in advance.
NOSE DN
Allows easy adjustment of the Autopilot’
s active pitch target. Each press of the NOSE DN button
will perform the following action for each of the AP pitch modes:
•
VS mode: Lowers the VS target, thereby causing the autopilot to pitch the nose of
the aircraft down.
•
IAS mode: Raises the IAS target, thereby causing the autopilot to pitch the nose of
the aircraft down.
•
ALT HOLD mode: Immediately changes the active mode to VS, and sets the initial VS
to the Default Descent Vertical Speed configured during setup. This allows you to
start a descent at a commonly-used vertical speed of your choosing with a single
button press.
NOSE DN will be unavailable and grayed-out if the active mode is not VS, IAS or Altitude Hold.
NOSE UP
Allows easy adjustment of the Autopilot’s active pitch target. Each press of the
NOSE UP button
will perform the following action for each of the AP pitch modes:
•
IAS mode: Lowers the IAS target, thereby causing the autopilot to pitch the nose of
the aircraft up.
•
VS mode: Raises VS target, thereby causing the autopilot to pitch the nose of the
aircraft up.
•
ALT HOLD mode: Immediately changes the active mode to VS, and sets the initial VS
to the Default Descent Vertical Speed configured during setup. This allows you to
start a climb at a commonly-used vertical speed of your choosing with a single
button press.
