5.1.5.1. Invalid GPS
If the aircraft GPS position data is no longer available or becomes invalid:
• The associated flight plan and basemap data are retained and displayed as long as
aircraft position information is provided from the selected GPS.
• The flight plan and waypoints become inactive and are displayed in white.
• The aircraft position is provided by:
1. Another configured GPS source is providing valid position data. In this case, a
GPS# REVERSION annunciation is shown in the Data Bar
(
Figure 5-10
) (“#” indicates the configured GPS source that is now providing
the aircraft’s position, either 1 or 2).
2. The RSM GPS, if enabled, and position data are available. In this case, a RSM
GPS REVERSION EMER USE ONLY annunciation is shown in the Data Bar
(
Figure 5-11
).
If a secondary GPS is not available then the EFD1000 MFD will use the RSM GPS (the
EFD500 MFD does not have an RSM). The annunciation RSM GPS REVERSION EMER
USE ONLY will display in the Data Bar (
Figure 5-11 ). The flight plan data is retained
and displayed, however no flight plan legs or waypoints are rendered as active
(magenta color).
When a GPS source’s position data are invalid or no longer available, an amber
annunciation, GPS1, GPS2, or RSM GPS, is shown to the left of the lower display to
indicate which has failed (
Figure 5-12 ). If Basemap features are invalid or unavailable
they are not rendered and the automatic moving map feature is lost. Position awareness
can be maintained by manually panning the map and visually associating the outside
view with the displayed map position.

to be available when the GPS position source is not
available.
