When OBS is active, all FMS flight plan legs, waypoints, and identifiers
are removed from display. The remaining flight plan waypoints in the
waypoint list are grayed out, indicating the waypoints will not
automatically sequence.
The OBS flight plan leg TO the active waypoint is displayed as a
magenta line originating from the active waypoint and extending
500 NM in the direction that is opposite to the desired track. For
example, when the OBS course is 360, the magenta line extends from
the waypoint to 500 NM at a bearing of 180.
The OBS flight plan leg FROM the active waypoint is displayed as a
white line originating from the active waypoint and extending 500 NM
in the same direction as the desired track. For example, when the OBS
course is 360, the white line extends from the waypoint to 500 NM at
a bearing of 360.
OBS mode is canceled by selecting the OBS bezel softkey and
pushing the UNDO bezel softkey shown in Figure 15--80.
