5.13 OPERATION WITHOUT A DATABASE
CARD
The KLN 900 is designed so that a database card is
required for normal operation. However, in the event
that the card is inadvertently not inserted or that the
card fails, there is a reversionary mode providing partial
operation that may be used.
NOTE: Reversionary operation without a database card
should only be used for VFR flight, not for IFR.
Without a database card inserted, the Database page
appears as in figure 5-136. All published waypoints
(those that originated from the database card) have
been deleted from the active flight plan, FPL 0.
Therefore, the only waypoints remaining in FPL 0 are
any user-defined waypoints that were originally included
in the flight plan.
The KLN 900 is unable to calculate magnetic variation
without the database card. Therefore, a magnetic varia-
tion must be manually inserted on the Database page
when there is no card. Use the right inner and outer
knobs to enter the desired magnetic variation and press
E to enter (figure 5-137). With the cursor positioned
over ACKNOWLEDGE?, press E to approve the
Database page. The magnetic variation can be entered
on the Database page and on line 6 of the SET 2 page
(figure 5-135).
The active flight plan is the only flight plan available
when there is no database card. There is no way to
gain access to flight plans one through 25. Functions
not requiring the published database are operative.
Some functions, such as nearest airport, nearest VOR,
nearest NDB, reference waypoint, and trip planning, are
operational but only to the extent that user-defined way-
points are utilized. Functions that depend on the data-
base card are not operative. Some of these include
Special Use Airspace, Minimum Safe Altitudes, ARTCC
waypoints, FSS frequencies on the OTH 1 page, and
ARTCC frequencies on the OTH 2 page. Non-precision
approaches, SIDs and STARs are also disabled.
If the database card is removed after the unit has been
powered up, the message in figure 5-138 appears. This
message will be displayed until power has been cycled.
Should the database card be reinserted the unit will
reinitialize.
