3D-16. SUPPLEMENTAL WAYPOINT PAGE.
a. Supplemental Waypoint Page Display.
Supplemental waypoints are user-defined waypoints
that have not been defined specifically as an airport,
VOR, NDB, or Intersection. Supplemental waypoints
also include ARTCC center waypoints and reference
waypoints discussed later. The following information
is displayed on the supplemental waypoint page.
1. The name of identifier of the supplemental
2. The position of the supplemental waypoint
expressed in terms of a radial and
distance from a nearby VOR.
The identifier of another nearby waypoint may be
entered in the REF field and the page will compute
and display the radial and distance from the nearby
waypoint to the supplemental waypoint. This radial
and distance is not stored with the supplemental
waypoint page and is lost when leaving the page.
3D-17. USER-DEFINED WAYPOINTS.
Up to 250 user-defined waypoints may be
created. These waypoints may be defined as a user-
defined airport, VOR, NDB, or intersection. If the
waypoint doesnt fit into one of these categories, it may
be defined as a supplemental waypoint.
a. Creating a User-Defined Airport Waypoint.
A user-defined airport waypoint must contain an
identifier, latitude, and longitude. In addition, any
combination of airport elevation, one runway length,
and associated runway surface, and remarks can also
be stored. Communication frequencies cannot be
stored on the APT 4 page, airport services cannot be
stored on the APT 6 page, SID's and STAR's cannot
be stored on the APT 7 page, and approach
procedures cannot be stored on the APT 8 page.
1. Use the right outer knob to select the
airport waypoint pages.
2. Rotate the right inner knob to select the
APT 1 page.
3. Press the right CRSR button to turn on the
right cursor function. The cursor will
appear over the first character of the
4. Use the right inner and outer knobs to
select the identifier of the user waypoint.
The identifier can be up to four characters
in length. Refer to Figure 3D-28.
5. To create a waypoint at the present
clockwise to position the cursor over
PRES POS? and press the ENT button.
The APT 1 page will now be displayed
with the latitude and longitude of the
waypoint at the bottom of the page.

6. To create a waypoint at a specified
position, place the cursor over USER
POS? and press the ENT button. A page
with the identifier at the top and dashes at
the bottom will now be displayed. Refer to
