Entegra EXP5000 PFD -40- 600-00157-000 Rev. 06
S-TEC 1500 Horizontal Modes
This section describes horizontal and flight director modes supported
by the EXP5000.
● Heading Capture/Hold Mode—Press the Hdg Bug button on the
PFD and rotate the right knob to set a desired heading. Press the
HDG button on the autopilot control head to engage heading
mode. The autopilot will track the input heading. The autopilot
control head will annunciate HDG. Select a new heading at any
time while the autopilot is in heading mode and the autopilot will
track the new heading bug value.
● Nav/Apr Mode—Press the NAV button on the autopilot control
head to engage Nav mode.
■ If the nav source on the PFD is NAV = GPS1 or GPS2, the
autopilot will fly the active flight plan using GPS roll steering
and will annunciate NAV GPSS.
■ If the nav source on the PFD is Nav = VLOC1 or VLOC2, the
autopilot will fly the active VOR or localizer signal.
■ When a localizer is the active Nav source, the autopilot will
automatically transition to APR mode when the localizer is
captured and will annunciate NAV APR.
■ Glideslope capture is supported when the autopilot is in NAV
APR mode and ALT (altitude hold) mode.
Note: The autopilot can be coupled only to a Nav source selected on the
PFD; it cannot be coupled to a Bearing source.
Note: See the S-TEC 1500 faceplate for engaged mode annunciation.
