Controlling the Autopilot
600-00142-000 Rev 01 -33- Entegra EXP5000 PFD
Altitude Capture Mode (S-TEC 55X only)
Push the Alt Bug button on the EXP5000 and rotate the right knob on
the EXP5000 to set a desired target altitude. Engage Altitude Capture
mode by simultaneously pressing the ALT and VS buttons on the
autopilot control head. The Alt Bug and VSI Bug will become solid
magenta, while the Flight Director steering command bars, if
configured on the aircraft, are shifted to correspond with the autopilot
commands.
● In autopilot mode, the autopilot control head and the EXP5000
autopilot annunciation bar will indicate “AP”, and the autopilot will
follow the VSI Bug to the selected target altitude.
● In Flight Director mode, the autopilot control head and the
EXP5000 autopilot annunciation bar will indicate “FD”, and the
Flight Director command bars will move to the appropriate
location, but it is your responsibility to match the command bars.
As the target altitude is approached, the VSI Bug will automatically
move toward zero and will become hollow when the target altitude is
captured. At the target altitude, the delta-shaped aircraft reference
symbol is tucked into the Flight Director command bars.
Autopilot Operation During PFD Failures (S-TEC 55X only)
In the unlikely event of a total PFD failure, the autopilot can still be
controlled via its control head. GPS roll steering (GPSS Mode) is the
only autopilot horizontal mode available. Alt Hold Mode and VS mode
are still available and may be controlled using the ALT and VS
buttons and the rotary knob on the autopilot control head. See the
autopilot POH for usage instructions.
About Flight Director (S-TEC 55X only)
The Flight Director is a display of the flight profile commanded from
the autopilot. Typically, a remote switch on the instrument panel
allows you to toggle control of the autopilot modes between autopilot
(AP), and Flight Director (FD).
!
When engaging the Altitude Capture Mode, confirm that both
ALT and VS are engaged on the autopilot. If VS is not
engaged the autopilot will level the aircraft at the current
altitude when ALT is engaged on the autopilot.
Note: Only Navigator1 is capable of being the navigation source to the
autopilot in the event of a PFD failure.
