Obs - Garmin 80 Pilot's Manual

When the Course From operation is executed, the CDI will indicate
FROM and the flightplan will go into suspend mode (SUSP); it will not
automatically sequence the flightplan waypoints.
1. Press Direct-To. Select a new waypoint, if desired, with the Large
and Small knobs.
2. Press CrsFr. A map is displayed showing the selected course.
3. Change the course bearing, if desired. Turn the Large knob to
change the 10's value. Turn the Small knob to change the 1's value.

OBS

This function activates the OBS mode where the CDI/HSI resolver con-
trols the selected course to a selected waypoint when an external
resolver is installed. This allows you to treat any waypoint as though it
were a VOR station. Automatic flight plan sequencing will be sus-
pended initially.
When using OBS mode for a VOR, station declination
provided by the database is used. This corresponds to
the magnetic variation actually used by the VOR rather
than the value calculated from your present position.
OBS to a Waypoint in Your Flight Plan
If the OBS waypoint is on the map display, a magenta line will be
drawn for the Course-To. After you intercept that line, the CNX80
will track the course inbound to the selected OBS fix. The white
line on the Map is the Course-From the OBS fix. Once the aircraft
intercepts the OBS course, the CNX80 will fly the course inbound
and then continue outbound until you terminate the OBS mode.
However, if you unsuspend, the CNX80 will terminate OBS mode
and continue to sequence en route on the flight plan. You will also
