Flying with the EXP5000
Entegra EXP5000 PFD -30- 600-00142-000 Rev 01
3.6 Controlling the Autopilot
Your Entegra EXP5000 is integrated with the S-TEC Fifty Five X
(55X) or S-TEC 55SR Autopilot. When you select an active autopilot
mode, full guidance is provided from the EXP5000 to the autopilot,
including heading captures and, for the S-TEC 55X only, smooth
transitions to altitude.
The status of the reference Bugs, autopilot annunciations, and Flight
Director steering command bars indicate when the EXP5000 is
coupled with the autopilot. A solid magenta Heading, Altitude, or VSI
(S-TEC 55X only) Bug indicates that the function is currently coupled
to an active mode of the autopilot. A hollow magenta Bug indicates
that the function is not currently coupled to the autopilot in an active
mode. In other words, a hollow Bug indicates manual or “hand-flying”
status. For more information about the EXP5000 bugs, see Right
Buttons and Knob, on page 19.
In Flight Director-equipped aircraft (S-TEC 55X only), when using a
vertical mode of the autopilot, a set of Flight Director command bars
will indicate the required steering of the aircraft to achieve the
commanded tracking from the autopilot. In full autopilot mode, “AP”
will be in the autopilot annunciation field, the command bars will be
visible and magenta and the aircraft should track those bars very
precisely.
In Flight Director only mode, “FD” will be displayed in the autopilot
annunciation field, the command bars will be visible and green, and
you are expected to use the flight controls as required to track those
bars.
The following is a description of the six autopilot modes supported by
the EXP5000. The autopilot can only be coupled to the GPS/VHF
selected as the PFD Nav source. The autopilot cannot be coupled to
the GPS/VHF unit selected as the PFD Bearing source.
Horizontal Modes
Heading Capture/Hold Mode (HDG Mode)
Press the Hdg Bug button on the EXP5000 and rotate the right knob
to set a desired heading. Press the HDG button on the autopilot
control head to engage heading mode. At this point, the Heading Bug
Note: A small amount of jitter of the command bars when in FD mode is
considered normal.
