A “1” for “Remote Baro” will cause the system to use the baro set input from the altimeter and

disable the ability to change baro set from the FCC (although it will still display baro set when

the BARO button is pressed).

A “1” for “HSI/DG” will select the proper operation for a system with an HSI. A “0” is the proper

selection for a DG installation.

A “1” for “Trim Installed” will configure the system to provide Manual Electric Trim. Autotrim will

also be provided in a two--axis system.

A “1” for “NAV Force Valid” will cause the system to always treat the NAV deviation as valid,

ignoring the NAV Valid input. This option should be chosen only if NAV Valid is not available in

the installation.

3. After selecting the desired options, press <CR> to return to the main menu. Now cycle power

to force the system to perform a preflight test. The PFT should now pass. If not, check the error

log and determine problem.

2.3.3.2 System Offset Adjustments

After the system has been installed, sensor offsets need to be nulled for optimum system

performance. These adjustments are stored in the configuration module and may be repeated,

as desired, without performing installation setup again. Adjustments of the pitch and roll axis

nulls are made with the single--turn potentiometer on the front panel of the flight computer

(right--hand side of the display).

W ARNING

A MINIMUM OF 10 MINUTES SHOULD BE ALLOWED FOR THE

FCC TO FULLY COMPUTE AND STORE VERTICAL

ACCELERATION NULL DATA T O THE KCM 100

CONFIGURATION MODULE. WHEN INSTALLING A NEW FCC

AND/OR A NEW KCM 100 CONFIGURATION MODULE, THE FCC

AUTOPILOT SYSTEM MUST ESTABLISH VER TICAL

ACCELERATION NULLS BEFORE ANY MANUAL ADJUSTMENTS

CAN BE MADE.

Apply power to the aircraft and to the KAP 140 autopilot system, allow the FCC to store the

vertical acceleration offsets to the KCM 100 configuration module. The aircraft should be

stable during the alignment, with no movement or jarring. No FCC modes should be engaged

until the alignment process has been completed.

This procedure is required whenever the FCC and/or KCM 100 configuration module is/are

removed from the aircraft for servicing and reinstalled, or whenever either component is

replaced.
