FLIGHT INSTRUMENTS

OBS MODE

  NOTE: 

VNV is inhibited while automatic waypoint sequencing has been suspended.

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.
