OTHER WAYPOINTS DELETED - This message
appears when the message “WAYPOINT _____
DELETED” would be effective for more than ten way-
points.
POSITION DIFFERS FROM
LAST POSITION BY > 2NM or (POSITION DIFFERS
FROM LAST POSITION BY > 4KM) This message
appears when the GPS sensor first reaches the NAV
mode if the new position differs from the position when
power was turned off by more than two nautical miles.
POSITION OF
WPT HAS
CHANGED - (Position of Waypoint Has Changed) This
message appears when either the latitude or the longi-
tude of a waypoint used in a flight plan or the active
waypoint has changed by more than .33 minutes as a
result of updating the database. This message is dis-
played on the left side of the screen while the waypoint
page corresponding to the waypoint which changed is
displayed on the right side of the screen.
POSITIONS OF OTHER
WAYPOINTS HAVE CHANGED - This message
appears when the above message “POSITION OF WPT
HAS CHANGED” would be effective for more than ten
waypoints.
PRESS ALT TO SET BARO - This message appears
when the approach mode is armed. Press the ALT but-
ton to update the baro information for proper integrity
monitoring.
PRESS GPS APR FOR NAV - This message appears
after the NAV flag has been set due to a RAIM problem
while the unit is in the approach mode. By pressing the
GPS APR button, the unit will be able to restore
navigation information so that you can conduct a missed
approach based on navigation information provided by
the KLN 900.
RAIM NOT AVAILABLE
APR MODE INHIBITED
PREDICT RAIM ON STA 5 - This message appears
when integrity monitoring (RAIM) is predicted to not be
available at either the FAF or the MAP. The KLN 900
will not allow the unit to go into the approach active
mode until conditions improve. Turn to the STA 5
(Status 5) page to perform a RAIM prediction. The STA
5 page will give an indication of how long it will be until
RAIM is available so that the approach can be flown
using the KLN 900 (see section 6.1.9 for how to perform
a RAIM prediction). The STA 5 prediction can also be
performed prior to departure to insure RAIM at your
arrival.
B-5
NAV IND CRS FAIL
ENTER OBS CRS ON GPS - The message appears if
the unit is in OBS mode and a failure warning condition
is detected in the incoming ARINC 429 serial data. The
KLN 900 is still usable, but it is not able to ìreadî the
selected course from a CDI or HSI due, for example, to
the loss of a reference signal. When this message is
present, OBS information must be entered on the KLN
900 (Super NAV 5 page for example), rather than
selecting the course on a CDI or HSI.
NAV IND CRS FAIL
ADJ NAV IND CRS TO ___° - The message appears if
the unit is in LEG mode a failure warning condition is
detected in the incoming ARINC serial data. The KLN
900 is still usable, but it is not able to ìreadî the selected
course from a CDI or HSI due, for example, to the loss
of a reference signal. The CDI or HSI selected course
should be adjusted manually when this message is pre-
sent, particularly if the KLN 900 is coupled to a flight
control system.
NO GENERAL RS-232 IN DATA - This message
appears when no input is received on the RS-232 input
(such as from a fuel management or air data system).
If no source of RS-232 is interfaced, the receiver input
must not be configured properly. Refer to Service Center
for installation troubleshooting.
NO GPS RCVR DATA - (No Receiver Data) This mes-
sage appears when the KLN 900 fails a specific internal
test for the GPS receiver. This failure will prevent the
unit from providing any navigation capability.
OBS WPT > 200NM or (OBS Waypoint > 370 km)
This message appears when the KLN 900 is in the OBS
mode and the distance to the active waypoint is more
than 200 nautical milesor 370 kilometers. The system
will perform normally; however, at this distance the D-
Bar will be extremely sensitive to changes in selected
course.
OBS ANNUNCIATOR FAIL - This message appears
when there is a failure of the KLN 900 LEG annunciator
drive circuitry. To determine if the unit is in LEG or OBS
mode, 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.
OTHER KLN 900
NOT RESPONDING - This message appears when two
KLN 900 units are set up to operate in tandem mode
and no serial data is being received from the slave unit.
This KLN 900 is still usable.
