Appendix B - Message Page Messages - Honeywell KLN 900s Pilot's Manual

The following is a list of the messages that can appear
on the Message page. When the message prompt
appears, press MSG to view the message page. See
section 3.5 for an explanation of the Message page.
ACTV ANNUNCIATOR FAIL - This message appears
when there is a failure of the KLN 900 ACTV annuncia-
tor drive circuitry. To determine if the approach mode is
active you will need to look at the status line of the
KLN 900 because the annunciator will not be working if
this message has been given. Service the KLN 900 as
soon as possible.
ADJ NAV IND CRS TO 123° - (Adjust Navigation
Indicator Course to 123°) When this message appears,
the pilot should select the suggested course on the HSI
or CDI. When the KLN 900 is in the LEG mode, this
message occurs at the beginning of turn anticipation
(prior to reaching the active waypoint) if the upcoming
course change is greater than 5°. See section 4.2.2.
This message will also appear in installations where the
KLN 900 is interfaced with an HSI or CDI such that the
KLN 900 has the capability of reading the selected
course from the HSI or CDI. In the Leg mode it will
appear whenever the difference between the HSI's
selected course and the KLN 900's desired track (DTK)
is greater than five degrees.
ADJ NAV IND CRS - (Adjust Navigation Indicator
Course) This message will appear in installations where
the KLN 900 is interfaced with EFIS or with a mechani-
cal HSI through the optional KA 90 adapter. This mes-
sage appears when the difference between the HSI's
selected course and the KLN 900's selected course
(OBS) is greater than 0.5°. This usually happens only
when the external indicator is not slewed to a new value
defined by the KLN 900. Check the interface between
the KLN 900 and the external indicator to determine the
problem.
AIRDATA RECEIVER FAIL - This message appears if
the KLN 900 is interfaced with an air data system and
that system's outputs are not being received correctly by
the KLN 900. This is most often an installation or config-
uration related failure. Refer to Service Center for instal-
lation troubleshooting.
AIRSPACE ALERT - This message appears when the
estimated time to enter a special use airspace is
approximately 10 minutes or when the distance from an
area of special use airspace is less than two nautical
miles. See section 3.10.
ALTITUDE ALERT ANNUNCIATOR FAIL - This mes-
sage appears when there is a failure of the KLN 900

APPENDIX B - MESSAGE PAGE MESSAGES

If you need service or repairs made to your KLN 900,
please contact your local authorized Bendix/King ser-
vice center. If necessary, you may also send your
KLN 900 to the following address:

If you are shipping your KLN 900, be sure to include
a description of the problem, your name, your street
address, your phone #, fax #, and your e-mail
address. Remember to package the KLN 900 care-
fully and purchase insurance to protect the KLN 900
from damage during shipping.
Altitude Alert annunciator drive circuitry. Any Altitude
Alerting annunciators or audible alerts (if a Sonalert is
connected to this output) will not be working if this mes-
sage has been given. Service the KLN 900 as soon as
possible.
ALTITUDE FAIL - This message appears if the altitude
input to the KLN 900 fails. The altitude related features
of the KLN 900 will be disabled. There also may be
more RAIM related messages since altitude is not
available to help in the integrity calculations. This is
most often an installation or configuration related failure.
Have the installation checked as soon as practical to
determine the cause of the problem. Refer to Service
Center for installation troubleshooting.
ANALOG BARO SET FAIL - This message will only
appear on ORS 04 and later units. This message
appears when a problem is detected with the analog
barometric pressure setting from an air data (or similar)
system.
APT ELEVATION UNKNOWN - (Airport Elevation
Unknown) This message appears if the elevation of the
airport which would otherwise be used for the height
above airport alert is unknown.
