Course To (Cr sTo)
Course To operation allows you to select an inbound to the intercept
course for the selected waypoint. The default course for the operation
is the course from the present position to the selected waypoint. The
length of the magenta course to line will be the distance from the
present position to the selected waypoint or 20 NM; whichever is
larger to a maximum of 300 NM. Upon reaching the selected waypoint,
if the waypoint is in the active flight plan, the flightplan will sequence
to the next waypoint in the flightplan normally. Maps are always drawn
with True North at the top of the display (Up).

Course From (CrsFr)
The Course From operation allows you to navigate from a waypoint on
a pre-defined course. The default course for the Course From opera­tion will depend on whether the ownship symbol is heading toward the
selected waypoint or away from it. If the ownship symbol is heading
toward the selected waypoint, the default course will be the bearing
from the present position to the selected waypoint. If the ownship sym­bol is heading away from the waypoint, the default course will be the
bearing from your present position to the selected waypoint plus
180°. The length of the magenta course line will always be 100 NM.

OBS
This function activates the OBS mode where the CDI/HSI resolver con­trols 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 sus­pended initially.

Note

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.

Direct-To

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

Discontinuity
A Discontinuity is a message placed in the affected position in a flight
plan indicating the pilot needs to fill in more detail about the flight
plan. The CNX80 either needs to know how you want to go from way­point A to B or an inserted procedure doesn’t match the end of the en
route structure. You may delete the Discontinuity message after

resolving any conflicts by turning the Large knob to highlight it and
then pressing the CLR key. Deleting a discontinuity results in a fix-to-fix
direct nav path between those waypoints.

Pilot Nav Legs
When the “Pilot Nav” message appears on a leg in your flight plan it
means the CNX80 will not provide guidance on that leg. You will have
to use other flight instruments or autopilot modes to fly the given pro­cedure leg until intercepting the course to the next waypoint. Once
the intercept is complete the flight plan will sequence and begin pro­viding guidance to the waypoint.

The CNX80 will go into Suspend mode when the current leg is a Pilot
Nav leg. Pressing SUSP again sequences you to the next leg in the pro­cedure. As you arrive at the course the course deviation indicator will
begin to center and once again you may engage the appropriate NAV
mode on your autopilot or flight director.

Parallel Track (PTK)

The Parallel Track function allows you to create a parallel course offset
of 1 to 99 nm to the left or right of your current flight plan. You must
have FROM and TO waypoints defined. Parallel Track cannot be acti­vated if you set a course using Direct-To. Choose Left or Right of the
current course, and the offset distance. When Parallel Track is acti­vated, the course line drawn on the Map pages will show the parallel
course, a PTK annunciation will be shown in the lower left corner of
