Altitude Hold (ALT) Mode

The Altitude Hold (ALT) mode
maintains the pressure altitude
acquired upon selection of altitude
hold. The ALT button toggles
between altitude hold and vertical
speed modes.
To operate in the ALT mode
(with autopilot currently in the
Vertical Speed mode):
1. ALT button - Press. Note ALT
is annunciated and autopilot
maneuvers to maintain pressure
altitude acquired at button selec-
tion.
2. UP or DN button - Select to
change altitude. Incremented but-
ton strokes will move the refer-
ence altitude by 20 feet per press,
or if held continuously will com-
mand a 500 ft/min altitude change,
acquiring a new reference altitude
upon button release.
Note: Incremented altitude changes
should be limited to 500 ft. of
change.
