expires or the date it expired. Press

to acknowledge the information
displayed on this page.
4. A page displaying the letters
PRESENT POS
at the top will now be on
the left side of the screen. In a couple of minutes or less, this page will
display the aircraft’s present position. It shows the position both in lati-
tude/longitude and in terms of the radial and distance from a nearby
VOR. Verify that the position is correct before proceeding.
5. Press the
D
button. A page with the words
DIRECT TO
is now
displayed on the left. In step 6 you will enter the identifier of the destina-
tion airport. The identifier will have a “K” prefix for a Continental U.S. air-
port, a “C” prefix for a Canadian airport, or a “P” prefix for an Alaskan air-
port if the identifier is all letters. For example, LAX becomes KLAX. If
the airport identifier contains any numbers, there is no prefix. For
example, TX04 is entered as TX04. For other areas of the world the
airport identifier entered should be identical to how it is charted.
6. Rotate the left inner knob until the first character of the airport identifier is
displayed. Turn the left outer knob one step clockwise to move the
flashing segment to the second character position. Rotate the left inner
knob to select the second character of the identifier. Use this procedure
to enter the complete airport identifier.

E
. The right side will display a page showing the identifier,
name, and position of the airport just entered. Confirm that the correct
airport is displayed. Press
E
a second time to approve the airport
data.
8. A Navigation page is now on the right side of the screen. It displays the
distance, ETE, and bearing to the destination airport. In addition, it dis-
plays groundspeed, and a course deviation indicator. If the left inner
knob is rotated one step counterclockwise, you will get an enlarged
Navigation page occupying the entire screen.
This abbreviated operation manual describes many of the frequently used
features of the KLN 90B in a condensed format for your convenience. It
does not replace the KLN 90B Pilot’s Guide. The KLN 90B has many very
useful features which are not described in this manual. Be sure to keep
your KLN 90B Pilot’s Guide with you in the aircraft to use as a reference.
