4.4.11.
Ground Track Marker
When configured with a GPS that provides ground track data, a Ground Track Marker is
displayed on the compass scale to indicate the aircraft’s ground track. This marker may be
used to compensate for wind drift during flight (
Figures 4-54 and 4-55
). The Ground Track
Marker is removed from the display when ground track data is not available or invalid.
4.4.12. GPS OBS Operation with a EFI and a Mechanical
Standby Nav Indicator
When the EFI and a mechanical standby Nav indicator are both connected to an integrated
VOR/GPS Navigation system, the standby indicator and the EFI operate normally in all VOR,
GPS and localizer modes.
When the GPS OBS mode is selected, the EFI Selected Course (CRS) control commands the
GPS OBS course and the mechanical standby nav indicator’s OBS course selector is ignored by
the integrated navigation system. Deviation indications are shown on both displays. When
the EFI is turned off, the course selector on the mechanical standby Nav indicator commands
the GPS OBS value.
4.4.13. Course Pointer Operation with Integrated VOR/GPS
Navigation Systems
During manual or automatic operation of the integrated system, when transitioning from GPS
guidance to VOR or localizer guidance, the course pointer on the E5 Dual EFI should manually
be set to the appropriate course.
