2.5 Navigation Source Select Buttons
The three buttons on the bottom of the PFD (Figure 2-7) allow the pilot to select the
navigation source for the CDI and Bearing Pointers
2.5.1 CDI Navigation Source Select Button
The CDI Nav Source Select Button is the center button (Figure 2-16). 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 a round-robin sequence.
The currently coupled CDI nav source is displayed directly above the CDI Nav Source
Select Button.
The available navigation sources are configured when the PFD was installed (depending
on what is installed in the aircraft and connected to the PFD). The available navigation
source choices are: GPS1, GPS2, VLOC1, and VLOC2.
If a navigation source is configured to be available, but is not providing valid navigation
data, its navigation source annunciation will be shown with a red slash through it, and
the CDI will not be shown with the Course Pointer. The pilot is able to select the invalid
source, but no navigation data is provided.
When one or more of the connected navigation sources is a combined GPS/Nav device,
the list of navigation sources available for selection will be determined by the current
CDI mode of the GPS navigator.

that source will be shown as invalid until an active flight
plan or direct-to waypoint is programmed into the GPS.
