1. KLN 35A SYSTEM COMPONENTS
A basic KLN 35A system consists of a panel mounted KLN 35A GPS
and a KA 92 GPS antenna. An altitude input is required to obtain full
navigation and operational capabilities. Additional system compo-
nents may be added or interfaced to the KLN 35A which increase its
features and capabilities. Some of these optional components
include an external course deviation indicator (CDI) or horizontal situ-
ation indicator (HSI), ARTEX ELS-10 emergency locator transmitter
(ELT), autopilot, and external annunciators.
The KLN 35A panel mounted unit contains the GPS sensor, the navi-
gation computer, a liquid crystal display (LCD), and all controls
required to operate the unit.
A KA 92 GPS “patch” antenna is available for use with the KLN 35A.
It is designed to always be mounted on the top of the aircraft.
The KLN 35A has analog outputs to drive the left-right deviation bar
of most mechanical CDIs and HSIs. In addition, the NAV mode of
the Bendix/King KFC 150, KAP 150, KAP 150H, KAP 100, KFC 200,
KAP 200, KFC 250, KFC 275, KFC 300, and KFC 325 flight control
systems may be coupled to the KLN 35A. Many other autopilots may
also be coupled to the KLN 35A. Actual autopilot performance and
capability when coupled to the KLN 35A may vary significantly from
one autopilot model to another.
Altitude may be provided to the KLN 35A from an encoding altimeter
or blind encoder. Altitude is used as an aid in position determination
when not enough satellites are in view.
Some installations may require remote annunciators to be mounted
in the aircraft panel in order to indicate the status of certain KLN 35A
functions, namely waypoint alert and message.
