EFD1000 C3 Pro PFD Pilot’s Guide
NOTE
Not all autopilots operate in the manner described
here for intercepting courses. See the AFMS for your
autopilot installation to understand how to adapt
these example procedures to your particular autopilot.
NOTE
In order for the autopilot to couple to vertical guidance
on GPS WAAS approaches, most autopilots must rst
be established on the nal approach course and in the
Altitude (ALT) Hold mode at least two miles outside the
Final Approach Fix (FAF). The Approach (APPR) mode
must be annunciated on both the PFD and the GPS.
NAV Mode Operation – GPS Navigation
1. With a valid ight plan programmed and active in the GPS, use the CDI
Source Select Button to couple the GPS to the PFD (see Section 4.4.5.).
2. If AUTOCRS is disabled, set the Course Pointer to the desired course (CRS) (see
Section 4.4.7.), or enable AUTOCRS (see Section 4.4.6.).
3. With GPSS disabled, set the PFD Heading Bug (see Section 4.4.9.) to a value
that will intercept the active leg of the ight plan, or enable GPSS via the
GPSS Hot Key.
4. Engage the autopilot in Heading (HDG) mode and verify that the aircraft turns
to a heading to intercept the active leg of the ight plan.
5. If your autopilot supports automatic heading to nav mode transitions, arm
the navigation capture on the autopilot by selecting its Navigation (NAV)
mode. Otherwise, select the autopilot’s Navigation (NAV) mode when the
autopilot navigation signal capture criteria are satised (see your autopilot
AFMS for more information).
6. Monitor the PFD CDI deection and verify that, upon intercepting the ight
plan leg, the autopilot modes transition appropriately and the autopilot tracks
the desired course.
