Navigation 6-11
In OBS FROM (defined as when the difference between the
selected OBS course and the aircraft course to the fix is greater
than or equal to 90°), the system will activate the reciprocal
course away from the station with guidance away FROM the fix.
The previously active TO leg will change to white and remain in
pivot. The assumption here is that you will want to fly the leg on
the 180° plane between the aircraft and the fix. If the TO leg is
within this plane, you will fly to the station. If you swing the TO
leg to the opposite plane, the FROM leg would now be in the 180°
plane between you and the fix, and that is the leg to fly
– away
from the station.

TIPS AND TECHNIQUES
OBS “Final”
OBS mode can be used to create a user-defined
course into a waypoint/fix or an airfield. Once in
OBS mode, use the external course knob to set the
desired inbound course to the fix or airfield. All
guidance, including that sent to an autopilot, will now
be with respect to that user-defined course.
