FLIGHT INSTRUMENTS
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 (see Figure 2-28).
While OBS Mode 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 path on the moving map retains the modified course line.
Enabling/disabling OBS Mode while navigating a GPS flight plan:
1) Select the OBS Softkey to select OBS Mode.
2) Turn the CRS Knob to select the desired course to/from the waypoint. Press the CRS Knob to synchronize the
Selected Course with the bearing to the next waypoint.
3) Select the OBS Softkey again to return to automatic waypoint sequencing.
