OBS MODE
VNV is inhibited while automatic waypoint sequencing has been suspended.
NOTE:
Enabling Omni-bearing Selector (OBS) Mode suspends the automatic sequencing of waypoints in a GPS
flight plan (GPS must be the selected navigation source), but retains the current Active-to waypoint as the
navigation reference even after passing the waypoint. OBS is annunciated to the lower right of the aircraft
symbol when OBS Mode is selected.
While OBS is enabled, a course line is drawn through the Active-to waypoint on the moving map. If
desired, the course to/from the waypoint can now be adjusted. When OBS Mode is disabled, the GPS flight
plan returns to normal operation, with automatic sequencing of waypoints, following the course set in OBS
Mode. The flight plan on the moving map retains the modified course line.
