3.4.3 Alternative Waypoint Data Entry Method
There is another method of data entry for waypoints
which you will sometimes find convenient. This method
applies when there is a page on the left side of the screen
with the cursor over a field where a waypoint is enterable.
You may fill the waypoint field on the left side by first
selecting the desired waypoint page on the right side (fig-
ure 3-48). When E is pressed, the waypoint field on the
left will contain the flashing identifier of the waypoint that
is displayed on the right side (figure 3-49). To finalize the
section, E is pressed again (figure 3-50).
3.4.4 The Duplicate Waypoint Page
There are some waypoints in the database whose identi-
fiers are not unique. That is, more than one waypoint has
the same identifier. When a waypoint identifier has been
entered which is not unique to a single waypoint, a
Duplicate Waypoint page appears on the left side (figure
3-52). The Duplicate Waypoint page is used to select
which of the waypoints having the same identifier is actu-
ally desired. The waypoint identifier is displayed on the
top left of the page. To the right of the identifier is the
number of waypoints in the database having the identifier.
Below the identifier is a list of the waypoint types (APT,
VOR, NDB, INT, SUP) and the associated countries
which use the identifier. To see an example of a
Duplicate Waypoint page perform the following steps:
1. Press D
2. Turn the left inner knob to select the letter “D” as a
waypoint identifier (figure 3-51). “D” is the full identifier of
several waypoints in the KLN 90B database.
3. Press E. The Duplicate Waypoint page will be dis-
played on the left side (figure 3-52). At the time of this
writing, there were ten waypoints in the database having
the identifier “D”. As in this example, if there are more
than four waypoints having the same identifier, only the
first four are initially shown. The list includes an NDB in
Canada, an NDB in Cuba, an NDB in the United States,
and an NDB in Libya. The cursor will be over the first
waypoint listed. They are listed with the waypoint closest
to the aircraft’s present position displayed first and the
waypoint farthest from the aircraft displayed last. To view
the rest, rotate the left outer knob clockwise. Doing so
will move the flashing cursor over waypoints two, three,
and four and then will cause the waypoint list to “scroll” so
that the other waypoints in the list may be seen. To
select the desired waypoint, move the cursor over the
appropriate choice (figure 3-53).
4. Press E to view the waypoint page for the selected
waypoint (figure 3-54).
5. Press E to approve the waypoint page.
