Operation when connected to P4001/5001:
GPS OBS Operation with an EFD1000 E5 and a Mechanical Standby Nav Indicator
When the EFD1000 E5 and a mechanical standby Nav indicator are both connected to an integrated VOR/Localizer/
GPS Navigation system, the standby indicator and the EFD1000 E5 operate normally in all VOR, GPS and localizer
modes.
When the GPS OBS mode is selected, the EFD1000 E5 course selector commands the GPS OBS course and the
mechanical standby nav indicator OBS course selector is ignored. The left/right indications are shown on both
displays. When the EFD1000 E5 is turned off, the course selector on the mechanical standby Nav indicator
commands the GPS OBS value.
Course Pointer Operation with Integrated VOR/Localizer/GPS Navigation Systems
During manual or automatic operation of the integrated system, when transitioning from GPS guidance to VOR or
localizer guidance, ensure that the course pointer on the EFD1000 E5 is set to the appropriate course.
