Altitude Hold Mode
1. Manually fly the airplane to the desired altitude and level off.
2. Press HDG, NAV, GPSS, APR, or REV to engage a roll mode. The
associated annunciations will illuminate.
3. Press ALT on the Programmer/Computer. The ALT annunciation
will illuminate indicating that the mode is engaged and the
autopilot will hold the present altitude.
Manually flying the airplane off the selected altitude will not
disengage altitude hold and the autopilot will command a pitch
change to recapture the altitude when the control input is
released.
Altitude can be changed to another altitude by rotating the VS
knob on the Programmer/Computer.
Engagement of the altitude hold mode will reset the PFD Altitude
Bug to the captured altitude.

speed mode. The VS annunciation will illuminate indicating that
the mode is engaged and the autopilot will synchronize to and
hold the vertical speed at the time the mode was engaged.
The vertical speed is displayed in 100-foot increments at the far
right of the Programmer/Computer window next to the VS
annunciation. A plus (+) value indicates climb and a negative or
minus (-) value indicates descent.
4. Vertical speed can be adjusted by rotating the VS knob on the
Programmer/Computer.
