Introduction

Introduction
The KAP 140 Autopilot System is a
rate based digital autopilot system
offering smooth performance and
enhanced features found only in
more expensive autopilots. The first
of its type developed by Honeywell,
this system brings digital technology
and reliability into the light aircraft
cockpit.
It is also significant that the KAP 140
series autopilots have been
designed from their inception to
interface with the Silver Crown pack-
age of products. Consider the
advantage of having your avionics
working together as an integrated
system rather than as a group of
components built by several manu-
factures.
Your new KAP 140 roll axis features
include wing leveler, heading select,
and VOR/LOC intercept and track-
ing. The KAP 140 can also be cou-
pled to GPS and RNAV receivers as
well. Roll rate information is derived
from the turn coordinator. Pitch axis
features include vertical speed,
glideslope and altitude hold along
with the optional altitude preselect.
Pitch information is derived from a
pressure sensor and accelerometer.
The KAP 140 Autopilot System oper-
ates independent of the aircraft’s
artificial horizon. Therefore, the
autopilot retains roll stabilization and
all vertical modes in the event of vac-
uum system failure.
Internal monitors keep constant track of the KAP 140’s status and provide for automatic shutdown of the autopilot or trim system in the event of a malfunction. In addition to relia­bility, the KAP 140 is designed to be easily maintained in the field. Qualified Honeywell Service Centers are located around the world to pro­vide assistance whenever neces­sary.
To fully realize the capability of your new panel mount digital autopilot system, you must understand the performance capabilities and basic operational requirements of the sys­tem. This pilot’s guide provides information to aid in this and is divided up into six sections. The first section provides general familiariza­tion of each autopilot system includ­ing the associated panel mounted displays. The second section describes the KAP 140 Single Axis Autopilot System. The third section describes the KAP 140 Two Axis Autopilot System. The fourth section describes the KAP 140 Two Axis/Altitude Preselect Autopilot System. The fifth section describes the optional KCS 55A slaved com­pass system. The Sixth section describes abnormal procedures.

Introduction

System Integration

The individual system diagrams on pages 5, 6, and 7 show the compo­nents and their relationship in typical KAP 140 Single Axis, KAP 140 Two Axis, and KAP 140 Two Axis/Altitude Preselect systems. The actual com­ponents on individual systems may vary slightly in order to optimize cer­tification and installation require­ments.
Each system has a number of inputs: sensor outputs are shown in red; combination inputs are shown in blue; display outputs are shown in orange; and aircraft control shown in green. The systems diagrams reflect that the KAP 140 systems control both pitch and roll axes of the aircraft.

KAP 140 Preflight Test Complete
A preflight test is performed upon power application to the com­puter. This test is a sequence of internal checks that validate proper system operation prior to allowing autopilot engagement. The preflight test (PFT) sequence is indicated by “PFT” with an increasing number for the sequence steps. Successful completion of self test is identified by all display segments being illumi­nated (Display Test) and the discon­nect tone sounding.
For two-axis units only:
NOTE: Following the preflight test, the red P warning on the face of the autopilot may illuminate indicating that the pitch axis cannot be engaged. This condition should be temporary, lasting no more than 30 seconds. The P will extinguish and normal operation will be available.
NOTE: The red P warning may illu­minate when the autopilot is not engaged. This can occur when autopilot G limits have been exceeded during turbulence or air­craft maneuvering. Autopilot engagement is locked out during red P illumination.
If power to the autopilot is cycled in flight (i.e. through the autopilot circuit breaker for instance) it is possible that a 5 minute delay may be neces­sary prior to autopilot engagement to allow the pitch axis accelerometer circuit to stabilize. Engagement prior to stabilization may result in mildly erratic pitch axis behavior.

1. AUTOPILOT ENGAGE/DISEN-
GAGE (AP) BUTTON - When
pushed, engages autopilot if all logic
conditions are met. The autopilot
will engage in the basic roll (ROL)
mode which functions as a wing lev-
eler. When pressed again, will disen-
gage the autopilot. For software ver-
sion 03/01 and later, the AP button
must be pressed and held for 0.25
seconds to engage the autopilot.
2. ROLL AXIS (R) ANNUNCIATION
- When illuminated, indicates failure
of the roll axis and will disengage the
autopilot and not allow engagement.
3. HEADING (HDG) MODE SELEC-
TOR BUTTON - When pushed, will
select the Heading mode, which
commands the airplane to turn to
HDG NAV APR REV
HDG NAV APR REV
and maintain the heading selected by the heading bug on either the DG or HSI. A new heading may be selected at any time and will result in the airplane turning to the new head­ing. Button can also be used to tog­gle between HDG and ROL modes. This button will engage the autopilot in units with software prior to soft­ware version 03/01.
4. NAVIGATION (NAV) MODE SELECTOR BUTTON - When pushed, will arm the navigation mode. The mode provides auto­matic beam capture and tracking of VOR, LOC or GPS as selected for presentation on the HSI or CDI. NAV mode is recommended for enroute navigation tracking.

5. APPROACH (APR) MODE SELECTOR BUTTON - When pushed, will arm the Approach mode. This mode provides auto­matic beam capture and tracking of VOR, GPS and LOC, as selected for presentation on the HSI or CDI. APR mode is recommended for instrument approaches.
6. BACK COURSE APPROACH (REV) MODE SELECTOR BUTTON
- When pushed, will arm the Back Course approach mode. This mode functions similarly to the approach mode except that the autopilot response to LOC signals is reversed.
7. ROLL MODE DISPLAY ­Displays the active and armed roll modes (ROL, HDG, NAV ARM, NAV, APR ARM, APR, REV ARM, REV). Also displayed will be flash­ing AP annunciation (5 seconds) at each autopilot disconnect accompa­nied by an aural tone (for 2 sec­onds).
8. AUTOPILOT ENGAGED (AP) ANNUNCIATION - Illuminates whenever the autopilot is engaged. Flashes during pilot initiated or auto­matic disengagement. Only applica­ble for software versions 03/01 or later.
