Instruction Manual

Handbook to troubleshoot the problem. You may desire to turn off
some of the aircraft's electrical devices which are non-essential for
your particular phase(s) of flight, so that the battery will not discharge
as quickly.
Appropriate alert voltage and alert delays will vary from aircraft to air-
craft. If your KLN 89(B) is frequently giving you this alert message, it
may become a nuisance, and you may desire to have your
Honeywell Service Center adjust the voltage alert parameters.
3.17. SPECIAL USE AIRSPACE ALERTING
The KLN 89(B) data base contains the location of areas of special
use airspace (SUA). The types of SUA areas stored in the data base
and the abbreviations used to denote these areas are the following:
Class B CL B
Class C CL C
Control Area (used outside USA) CTA
Terminal Area (used outside USA) TMA
Alert Area ALRT
Caution Area CAUT
Danger Area DNGR
Military Operations Area MOA
Prohibited Area PROH
Restricted Area REST
Training Area TRNG
Warning Area WARN
Terminal Radar Service Area TRSA
The KLN 89(B) will normally alert you
prior to entering one of these areas
with a message prompt. When the
Message page is viewed it will display
Airspace Alert and will also display
the name and type of the special use
airspace (figure 3-200). If the special
use airspace is a Class B, Class C,
CTA, or TMA, the message page will
also instruct you to press the E but-
ton if you wish to see the Airport 5
page (airport communications) for the
primary airport so that the correct
communications frequency may be
determined (figure 3-201).
