KLN 94 Pilot's Guide Chapter 2 Data Base
A KLN 94 data card plugs into the left side of the KLN 94 front panel. The
land data resides full time in the data card. The KLN 94 accesses the
land data directly from the data card. The land data can only be updated
by inserting a new data card. New land data is generally available from
Honeywell about once a year.
The aeronautical data is initially contained in the data card. However, this
data is then downloaded automatically into an another memory area inter-
nal to the KLN 94. The aeronautical data may be updated by inserting a
new data card or by using a personal computer (PC) to update the internal
memory directly through the data port on the front of the KLN 94. New
aeronautical data is available from Honeywell every 28 days.
The user data is kept in a separate area of internal memory and is not
affected by updating of the aeronautical or land database.
The aeronautical database is designed so that there are three ways for
the user to keep the database current. The first method of database
update is to remove the old data card and insert a current card. This
method involves returning the old card to Honeywell.
The second and third methods involve electronically updating the data-
base by using an IBM-compatible personal computer to update the
internal memory directly via an interface cable that plugs into the data port
on the front of the KLN 94. Method two utilizes Honeywell supplied 3.5-
inch diskettes with the PC. The diskettes are not returned to Honeywell.
Method three allows for acquiring the update data from the Internet.
Every 28 days, Honeywell receives new NavData™ information from
Jeppesen Sanderson. This information is processed and downloaded
onto both diskettes and database cards. It is also made available to
Internet subscribers. Honeywell makes these three types of update ser-
vices available to you in a choice of several subscription or random
update programs. See section 2.6 for details on these programs.
NOTE: Honeywell sends the update so that it arrives prior to the next
effective date. The new update may be installed any time prior to the
effective date and the KLN 94 will use the previous data up to the effective
date and automatically begin using the new data on the effective date.
WARNING: The accuracy of the database information is only
assured if it is used before the end of the effectivity period. Use of
out of date database information is done entirely at the user's own
risk.
