9.0 NEAREST AIRPORTS, VORS, AND NDBS
9.1 Viewing The Nearest Airports, VORs, And NDBs
The KLN 90B computes the nine nearest airports, the nine nearest VORs,
and the nine nearest NDBs to the aircraft’s present position. There is no
“nearest” list for intersection and supplemental waypoints. To view the
nearest airports:
• Rotate the right outer knob to select the airport (APT) types.
• Pull the right inner knob to the “out” position.
• Rotate the right inner knob counterclockwise to initially scan through a
complete list of all airport identifiers backward in alphabetical order.
There are actually two waypoint scan lists. These two lists are the “com-
plete” list and the “nearest” list. The complete list contains all of the air-
port waypoints in the database. The nearest list consists of the nine
nearest airports to your present position.
The nearest list is positioned in front of the complete list. That is, you
must scan backwards through the complete list to reach the nearest list.
This is easy to do because the faster the knob is turned, the larger the
step is made through the 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 the present position (NR 1 indicates
the nearest). As you scan clockwise from NR 1, NR 2, NR 3, ..., NR 9 the
next scan position is the beginning of the complete list.
Waypoint pages displayed in the nearest list do not contain 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 runway. 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 airport page.
The procedure above is for viewing the nearest airports but it is equally
applicable to VORs and NDBs except that either VOR or NDB waypoint
types are selected in the first step.
9.2 Nearest Airports In An Emergency
In the event of an emergency, a special procedure exists to very quickly
get to the beginning of the nearest airport list:
