accuracy. This altitude input is used for altitude related features of the
KLN 900. Therefore, it is important to keep the altimeter baro setting
updated on the Self Test page when power is first applied to the KLN 900
and on the Altitude page each time a new baro correction is made to the
aircraft’s altimeter. The altimeter baro setting may be changed at a later
time from inches to millibars (or vice versa) on the SET 7 page. The
altimeter baro set field will not be a cursor field if the KLN 900 is interfaced
to certain air data/altimeter systems which update the baro set field when
the aircraft’s altimeter baro setting is updated.
To enter the correct baro setting, rotate the right inner knob to select the
first two digits of the correct altimeter setting. Rotate the right outer knob
one step clockwise to move the flashing cursor over the third position.
Use the right inner knob to select the correct number. Use the right outer
and inner knobs to complete the baro setting. Now press
E. With the
correct altimeter setting entered, the altitude displayed on line 4 should be
correct within 100 feet.
• Use the right outer knob to position the cursor over APPROVE (if the
cursor is not there already) and press E to approve the Self Test
page. (Note: If the KLN 900 is installed for VFR only operation, a VFR
only warning page is displayed after the self test page has been
approved. This warning page must be acknowledged by pressing
E.)
• The screen will now display the Database page, which shows the date
the database expires or the date on which it expired. Press E to
acknowledge.
WARNING: The accuracy of the database information is assured
only if it is used before the expiration date. Use of out-of-date data-
base information is done entirely at the user’s own risk.
• The NAV 2 page (present position) will now be displayed on the left side
of the screen and the waypoint page for the last active waypoint (before
the KLN 900 was last turned off) will be displayed on the right side. If
the last active waypoint was an airport, the APT 4 page (airport commu-
nications) will be displayed on the right side.
• When the KLN 900 is ready to navigate, the NAV 2 page will display the
present position both in terms of latitude/longitude and in terms of the
radial and distance from a nearby VOR.
