CHAPTER 6 EXPANDED EMERGENCY AND ABNORMAL PROCEDURES
EFD1000 C3 Pro PFD Pilot’s Guide
If all aircraft panel-mounted GPS receivers experience a failure, the RSM Emergency
GPS receiver will provide position data that is shared among all EFDs. In addition, a text
alert is presented at the bottom center of the Navigation Display annunciating RSM
GPS REVERSION EMER USE ONLY (Figure 6-23). This “sharing” feature permits any EFD
(as congured by the installer), to receive and display the RSM GPS position data, thus
assuring continuous navigational awareness to the pilot. In this case, the basemap data
is approved for emergency use only.
Whenever the map has reverted to an alternate position source, all map features and
capabilities are retained, including the display of the ight plan from the selected panel-
mount GPS. However, when the selected GPS is no longer providing position data, the
ight plan is displayed without an active (magenta) leg. The ight plan and basemap
data from each of the aircraft’s GPS receivers is retained independently. If two external
GPSs were connected prior to failure of both, and if each had a dierent ight plan at
the time of failure, both retained ight plans remain available to the pilot and may be
selected using the PFD’s Navigation Source Select Button.
In the unlikely event that there is a complete loss of all GPS data to the EFD, including
failure of the RSM GPS receiver, all mapping information would be removed from the
EFD display.
