Nearest" And "Complete" Waypoint Scan Lists - Honeywell KLN 900s Pilot's Manual

3.7.3 "Nearest" And "Complete" Waypoint Scan
Lists
There are actually two waypoint scan lists for airports,
VORs, and NDBs. These two lists are the "complete" list
and the "nearest" list. The complete list contains all of the
waypoints in the database for a waypoint type (all the air-
ports for example). The nearest list consists of the nine
nearest waypoints to your present position. Therefore, if
you are in the nearest airport list, it will contain the nine
nearest airports relative to your location. There is no
"nearest" list for intersections (INT) and supplemental
waypoints (SUP).
The nearest list is positioned in front of the complete list.
That is, you must scan backwards (turn the knob counter-
clockwise) through the complete list to reach the nearest
list. You will know when you have reached the nearest
list because the top right portion of the waypoint page will
flash the relative position of the waypoint to your position.
"NR1" indicates nearest (figure 3-71) while "NR 9" indi-
cates the ninth nearest (figure 3-72). As you scan clock-
wise "NR 1, NR 2, NR 3,...,NR 9", the next scan position
is the beginning of the complete list. The nearest list can
only be reached scanning backwards. It does not wrap
around after the last waypoint in the complete list.
Waypoint pages displayed in the nearest list do not con-
tain a latitude and longitude position as they do in the
complete list. Instead, the bearing and distance to the
waypoint are displayed. In addition, nearest airport pages
display the length, surface, and lighting of the longest run-
way. Once the nearest airport is being displayed, the
other airport pages (APT 2-APT 8) for that airport are
available for display by making sure the right inner knob
is pressed in and then turning it to select the desired air-
port page.
The nine airports in the nearest list are the nine airports
which meet the criteria selected on the Setup 3 page
(SET 3). The SET 3 page allows you to specify what cri-
teria you want an airport to meet before it is considered
for the nearest airport list. To specify the airport criteria:
1. Select the SET 3 page on the left side (figure 3-73).
2. Press the left C to turn on the left cursor function.
The cursor will appear over the minimum runway length
field.
3. Use the left inner knob to select the minimum length
runway desired for the airport to qualify for the nearest
airport list (figure 3-74). Values between 1000 feet and
5000 feet in 100 foot increments or between 300
meters and 1500 meters in 100 meter increments may
be selected.
4. Rotate the left outer knob one step clockwise to position
the cursor over the runway surface criteria (figure 3-75).
