2.2.2.1. CDI Nav Source Control
The center button of the three buttons between the control knobs at the bottom of
the EFD1000 Pro PFD (see Figure 2-7) is the CDI Nav Source Select Button. It selects
which of the available navigation sources will couple to the CDI, which in turn couples
to the autopilot (if available). Each press of the CDI Nav Source button selects the next
available nav source, cycling through all available sources in round-robin sequence. The
currently coupled CDI nav source is displayed directly above the CDI Nav Source Select
Button.
The available nav sources are congured when the EFD1000 is installed (depending on
what is installed in the aircraft and connected to the EFD1000). The available nav source
choices are: GPS1, GPS2, VLOC1 and VLOC2.
If a nav source is congured to be available, but is not currently putting out valid
navigation data, its identier will be shown with a red slash through it, and the CDI bar
will not be shown with the Course Pointer. The pilot will be able to select that invalid
source, but no navigation data will be provided.
When one or more of the connected nav sources is a combined GPS/Nav device (e.g.,
some of the Garmin 400/500-series), the list of nav sources available for selection will be
determined by the current CDI mode of that navigator.
NOTE
When GPS is selected as the nav
source, but no active waypoint is
programmed in the GPS navigator,
that source will be shown as invalid,
until an active ight plan or direct-to
waypoint is programmed into the
GPS.
NOTE
For example, with a Garmin GNS-430
installed as the #1 navigation source,
if “GPS” is shown immediately above
the CDI key on the GNS-430, then
the EFD1000 will show GPS1 as an
available nav source. If the pilot
presses the CDI key on the GNS-430
so that VLOC is now displayed on
the GNS-430, then the EFD1000 will
show VLOC1 as the available nav
source and GPS1 cannot be selected.
