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 package 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 manufactures.
Your new KAP 140 roll axis features
include wing leveler, heading select,
and VOR/LOC intercept and tracking. The KAP 140 can also be coupled 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 operates independent of the aircraft’s
artificial horizon. Therefore, the
autopilot retains roll stabilization and
all vertical modes in the event of vacuum system failure.
Rev. 1
Apr/02
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.

Full Two-Axis KAP 140 Display
1. PITCH AXIS, (P) ANNUNCIATOR
- When illuminated, indicates failure
of the pitch axis and will disengage
the autopilot when the failure occurs
and not allow engagement of the
pitch axis.
2. AUTOPILOT ENGAGE/DISENGAGE (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 leveler and in the vertical speed (VS)
hold mode. The commanded vertical speed will be displayed in the
upper right corner of autopilot display area. The captured VS will be
the vertical speed present at the
moment of AP button press. When
pressed again, will disengage the
autopilot. For software version 03/01
Rev. 2
May/02
and later, the AP button must be
pressed and held for 0.25 seconds
to engage the autopilot.
3. ROLL AXIS (R) ANNUNCIATOR
- When illuminated, indicates failure
of the roll axis and will disengage the
autopilot and not allow engagement.
4. HEADING (HDG) MODE SELECTOR BUTTON - When pushed, will
arm the Heading mode, which commands the airplane to turn to 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.
KAP 140 AUTOPILOT SYSTEM
55
Two Axis Operation
5. 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. NAV
mode may also be used for front
course LOC tracking when GS tracking is not desired.
6. APPROACH (APR) MODE
SELECTOR BUTTON - When
pushed, will arm the Approach
mode. This mode provides automatic beam capture and tracking of
VOR, GPS, LOC, and Glideslope
(GS) on an ILS, as selected for presentation on the HSI or CDI. APR
mode is recommended for instrument approaches.
7. 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, and GS is disabled.
8. ALTITUDE HOLD (ALT) MODE
SELECT BUTTON - When pushed,
will select the Altitude Hold mode.
This mode provides tracking of the
reference altitude. The reference
altitude is the altitude at the moment
the ALT button is pressed. If the
ALT button is pressed with an established VS rate present, there will be
altitude overshoot (approximately
56
10% of the VS rate), with the airplane returned positively to the reference altitude. This button will
engage the autopilot in units with
software prior to software version
03/01.
9. VERTICAL TRIM (UP/DN) BUTTONS - The action of these buttons
is dependent upon the vertical mode
present when pressed. If VS mode
is active, button strokes will increment the vertical speed commanded
either up or down at the rate of 100
ft/min per button press, or at the rate
of approximately 300 ft/min per second if held continuously. If ALT
mode is active, incremental button
strokes will move the altitude hold
reference altitude either up or down
at 20 feet per press, or if held continuously will command the airplane up
or down at the rate of 500 ft/min,
synchronizing the altitude hold reference to the actual airplane altitude
upon button release.
10. VERTICAL SPEED DISPLAY Displays the commanded vertical
speed in VS mode.
11. PITCH TRIM (PT) ANNUNCIATION - A flashing PT with arrows
indicates the direction of required
pitch trim. A solid PT without an
arrow head is an indication of a pitch
trim fault. During manual electric trim
operation (autopilot disengaged),
detection of a stuck MET switch will
be indicated by a solid PT. When the
fault is corrected, the annunciation
will extinguish.

Vertical Speed (VS) Mode
The Vertical Speed (VS) mode
allows variable vertical speed climbs
and descents. The ALT button toggles between altitude hold and vertical speed modes.
Note: The KAP 140 engages into VS
mode as a default.
To operate in the VS mode
(with autopilot currently disengaged):
1. AP button - Press. Note ROL,
VS and current vertical speed is
displayed. If no other modes are
selected the autopilot will operate
in the ROL and vertical speed
hold modes. For software version
03/01 and later, the AP button
must be pressed and held for 0.25
seconds to engage the autopilot.
2. UP or DN button - Select
desired climb or descent rate.
Each button stroke will increment
the vertical speed commanded up
or down by 100 ft/min per button
press, or at the rate of approximately 300 ft/min per second if
held continuously.
58
To initiate a climb or descent from
Altitude Hold (ALT) mode:
1. ALT button - Press. Note ALT
changes to VS and current vertical
speed is displayed.
2. UP or DN button - Select
desired climb or descent rate.
Each button stroke will increment
the vertical speed commanded up
or down by 100 ft/min per button
press, or at the rate of approximately 300 ft/min per second if
held continuously.
Note: When operating at or near the
best rate of climb airspeed, at climb
power settings, and using vertical
speed hold, it is easy to decelerate
to an airspeed where continued
decreases in airspeed will result in a
reduced rate of climb. Continued
operation in vertical speed mode can
result in a stall.

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. NAV mode may also
be used for front course LOC tracking when GS tracking is not desired.
6. APPROACH (APR) MODE
SELECTOR BUTTON - When
pushed, will arm the Approach
mode. This mode provides automatic beam capture and tracking of

- 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, and GS is disabled.
9. VERTICAL TRIM (UP/DN) BUTTONS - The action of these buttons
is dependent upon the vertical mode
present when pressed. If VS mode is
active, the initial button stroke will
bring up the commanded vertical
speed in the display. Subsequent
immediate button strokes will increment the vertical speed commanded
either up or down at the rate of 100
ft/min per button press, or at the rate
of approximately 300 ft/min per second if held continuously. If ALT
mode is active, incremental button
strokes will move the altitude hold
reference altitude either up or down
at 20 feet per press, or if held continuously will command the airplane up
or down at the rate of 500 ft/min,
synchronizing the altitude hold reference to the actual airplane altitude
upon button release.
(Note that the altitude hold reference
is not displayed. The display will
continue to show the altitude alerter
reference.)
10. ROTARY KNOBS - Used to set
the altitude alerter reference altitude;
or may be used immediately after
pressing the BARO button, to adjust
the autopilot baro setting to match
that of the airplane’s altimeter when
manual adjustment is required. (In
some installations the baro setting is
automatically synced to that of the
altimeter.)
8. ALTITUDE HOLD (ALT) MODE
SELECT BUTTON - When pushed,
will select the Altitude Hold mode.

vice versa. Once the baro setting
display is visible the rotary knobs
may be used to manually adjust the
baro setting if automatic baro correction is not available.
12. ALTITUDE ARM (ARM) BUTTON - When pushed will toggle altitude arming on or off. When ALT
ARM is annunciated, the autopilot
will capture the altitude alerter displayed altitude (provided the aircraft
is climbing or descending in VS to
the displayed altitude). When the
autopilot is engaged, ALT arming is
automatic upon altitude alerter altitude selection via the rotary knobs.
Note that the alerter functions are
independent of the arming process
thus providing full time alerting, even
when the autopilot is disengaged.
13. ALTITUDE ALERTER/VERTICAL SPEED/BARO SETTING DISPLAY - Normally displays the altitude alerter selected altitude. If the
UP or DN button is pushed while in
VS hold, the display changes to the
command reference for the VS
mode in FPM for 3 seconds. If the
BARO button is pushed, the display
changes to the autopilot baro setting
in either IN HG or HPA for 3 seconds.
NOTE: This display may be dashed

reached. Once the selected altitude
is reached a flashing ALERT illumination signifies that the 200 ft. “safe
band” has been exceeded and will
remain illuminated until 1000 ft. from
the selected altitude. Associated with
the visual alerting is an aural alert (5
short tones) which occurs 1000 feet
from the selected altitude upon
approaching the altitude and 200
feet from the selected altitude on
leaving the altitude.
15. PITCH TRIM (PT) ANNUNCIATION - A flashing PT with arrows
indicates the direction of required
pitch trim. A solid PT without an
arrow head is an indication of a pitch
trim fault. During manual electric trim
operation (autopilot disengaged),
detection of a stuck MET switch will
be indicated by a solid PT. When the
fault is corrected, the annunciation
will extinguish.
16. PITCH MODE DISPLAY Displays the active and armed pitch
modes (VS, ALT, ARM, ALT and
GS).
17. ROLL MODE DISPLAY Displays the active and armed roll
modes (ROL, HDG, NAV ARM,

auto intercept mode is cancelled and reverse
localizer mode is automatically activated and a
left turn outbound on the localizer is initiated by
the autopilot.
Note: The left-right deviations of the CDI course
deviation needle are reversed (you must turn right
to center a deviation of the index to the left). This
needle reversing takes place because you are flying outbound on a front course.

Lubber Line - A fixed white marker
at the top of the display that indicates aircraft magnetic heading on

KCS 55A Compass System
Selected Course Pointer - On this
two-part arrow, the “head” indicates
the desired VOR or Localizer course
and the “tail” indicates the reciprocal.
This pointer is set by rotating the
course select knob.
Course Select Knob - Used to
rotate the course pointer to the
desired course on the compass
card. This knob corresponds to the
Omni Bearing Selector (OBS) on
standard NAV indicators.
VOR/RNAV and LOC Deviation This bar corresponds to the
“left/right” needle on standard course
deviation indicators. When the aircraft is precisely on the VOR radial
or Localizer course, it forms the center section of the selected course
pointer and will be positioned under
the symbolic aircraft. When off
course or approaching a new
course, it will move to one side or
the other. Since the entire VOR and
Localizer display rotates with the
compass card, the angular relationship between the deviation bar and
the symbolic aircraft provides a pictorial symbolic display of the aircraft’s position with respect to the
selected course.
Deviation Scale - When tuned to a
VOR frequency, each white dot represents two degrees of deviation left
or right of course. When tuned to a
Localizer, the deviation is 1/2 degree
per dot. (When GPS data is selected
for presentation, refer to the Pilot’s
Guide for the GPS receiver.)
Rev. 0
Jun/98
Heading Select Bug - A movable
orange marker on the outer perimeter of the display, used primarily to
select the desired heading you wish
to fly. This desired heading is coupled to the KAP 140 Autopilot to provide the “Heading Select” function.
Heading Select Knob - Used to
rotate the heading select bug to a
desired point on the compass card.
To-From Indicator - A white triangle
near the center of the display that
indicates, with reference to the OBS
setting, whether the course selected
is “to” or “from” the selected VOR
station and/or RNAV waypoint.
Dual Glideslope Pointers Chartreuse triangular pointers on
either side of the display drop into
view when a usable glideslope signal is received and retract out of
view when the glideslope signal
becomes marginal. During an ILS
approach, these pointers represent
the vertical orientation of the aircraft
with respect to the center of the
glideslope beam. When on glideslope, the pointers will align with the
center markers on the glideslope
scale.
Glideslope Deviation Scale - White
dots on each side of the display
which, in conjunction with the glideslope pointers, indicate either
“above”, “below”, or “on glideslope”
during an ILS approach.

Compass Warning Flag - A red flag
labeled “HDG” becomes visible in
the upper right quadrant of the display whenever the electrical power is
inadequate or the directional gyro is
not up to speed. Compass failures
can occur which will not be annunciated by the “HDG” flag. Therefore,
periodic comparison with the
standby compass is advised.
NAV Warning Flag - A red flag
labeled “NAV” becomes visible in the
upper left quadrant of the display
whenever a usable signal is not
being received.
Slaving Meter ( KA 51B)
This meter indicates any difference between the displayed heading
and the magnetic heading. Right or
up deflection indicates a clockwise
error of the compass card. Left or
down deflection indicates a counterclockwise error of the compass card.
Whenever the aircraft is in a turn and
the card rotates, it is normal for this
meter to show a full deflection to one
side or another.
NOTE: During level flight it is normal
for the meter needle to continuously
move from side to side and to be
fully deflected during a turn. If the
needle stays fully deflected, left or
right, during level flight, the free gyro
mode can be used to center it, as
follows:

Slave and Free Gyro Switch - When
the switch is in the AUTO position,
the system is in the slaved gyro
mode. When the switch is in the
MAN position, the system is in the

Clockwise Adjustment - When the
system is in the free gyro mode,
holding the manual heading switch
to the CW position will rotate the
compass card to the right to eliminate left compass card error.
Counterclockwise Adjustment When the system is in the free gyro
mode, holding the manual heading
switch to the CCW position will
rotate the compass card to the left to
eliminate right compass card error.
The KA 51B Slaving Control

KMT 112 Magnetic Slaving
Transmitter
This unit senses the direction of
the earth’s magnetic field and continuously transmits this information
through the slaving circuitry to the

“drift”. This sensor is mounted
remotely – usually in a wingtip – to
eliminate the possibility of magnetic
interference.

Operating Instructions
1. Until power is applied to the
KCS 55A System, and the directional gyro is up to speed, a red
flag labeled “HDG” will be visible
in the upper right quadrant of the
KI 525A Indicator. In operation,
this warning flag will be visible
whenever the power being supplied is inadequate or the gyro is
not up to speed.
2. With the application of power to
the KCS 55A System, and gyro up
to operating speed, the red “HDG”
flag should disappear from view.

3. If the KCS 55A System is in the
slaved gyro mode, the compass
card will automatically fast slave at
the rate of 180 degrees per minute
toward the aircraft’s magnetic
heading. (Immediately after applying power, this compass card
movement should be quite visible.) It will continue to fast slave
until the proper magnetic heading
is indicated, after which it will
slave at a constant rate of three
degrees per minute to keep the
system aligned with the earth’s
magnetic field.
KAP 140 AUTOPILOT SYSTEM
117
KCS 55A Compass System
Under some conditions it is possible for the system to stop slaving
exactly 180 degrees from the correct heading. If this should occur,
move the “Slave” switch on the
KA 51B to the unslaved (free)
position. Rotate the compass card
±10 degrees from the incorrect
heading by using the manual rotation switch and then return the
system to slaved operation. The
system will then slave to the correct heading.
8. The VOR deviation bar represents
the selected course, and the relationship of this bar to the symbolic
aircraft in the center of the instrument visually presents the actual
relationship of the selected course
to your aircraft heading. (In other
words, if the symbolic aircraft on
the display indicates approaching
the deviation bar at 45 degrees,
that is the angle at which your aircraft is actually approaching the
selected course.
4. For the free gyro operation, check
the magnetic compass to determine the correct magnetic heading. Then use the manual slave
switch to align the system with the
earth’s magnetic field. Periodic
checks with the standby compass
are recommended to check and
correct for gyro precession.
9. To prepare for an ILS approach,
tune the NAV receiver to the
desired Localizer frequency. If a
usable Localizer signal is being
received, the NAV warning flag
will disappear.
5. Until a usable navigation signal is
being received by the NAV system, a red flag labeled “NAV” will
be visible in the upper left quadrant of the KI 525A Indicator. In
operation, this warning flag should
be visible whenever an inadequate navigation signal is being
received.
6. For normal navigation to or from a
VOR or VORTAC, set the NAV
receiver to the desired VOR or
VORTAC frequency and the red
navigation flag (NAV) should disappear from view if a usable signal is being received.
7. Rotate the course select knob to
position the course pointer to the
desired VOR course.
118
10. For a front or back course
approach, rotate the course select
knob to set the course pointer on
the inbound Localizer course. As
with normal navigation (#6 above),
the LOC deviation bar represents
the desired course. The relationship between this bar and the
symbolic aircraft gives a true picture of your aircraft’s position with
respect to the Localizer course.
Always setting the course pointer
to the inbound Localizer course
provides the correct deviation bar
sensing whether flying a front or
back course approach.
11. The glideslope deviation pointers
should become visible on both
sides of the display when a usable
glideslope signal is received. If
they do not come into view, a
usable glideslope signal is not
being received.
KAP 140 AUTOPILOT SYSTEM
Rev. 0

KCS 55A Compass System
12. The glideslope pointers indicate
the relative position of the glideslope path with respect to the aircraft. (In other words, if the pointers are above the center marker,
the aircraft is below the glideslope.)
Abnormal Circumstances
If the Warning Flag (HDG)
appears during operation, the compass card indications will be in error.
Power may be removed from the KG
102A Directional Gyro by pulling the
appropriate circuit breaker. The
Selected Course, VOR/LOC
Deviation Bar, the NAV flag, and the
To/From Indicator will remain in
operation.
If the Navigation Warning Flag
(NAV) appears during operation,
there are several possibilities: (1) the
NAV receiver is not turned on, (2)
the NAV receiver is improperly
tuned, (3) the ground VOR or LOC
station is malfunctioning, (4) the aircraft is out of range of the selected
ground station, or (5) the aircraft
NAV receiver has malfunctioned.
(The compass card will continue to
display the aircraft heading even if a
usable NAV signal is not being
received.
If the glideslope pointers
remain out of view during a front
course ILS approach, wither the aircraft glideslope receiver or the
ground station glideslope transmitter
is malfunctioning. Glideslope is usually not available during a back
course approach. (The VOR and
LOC course display will continue to
Rev. 0
Jun/98
function normally even if a usable
glideslope signal is not being
received.)
A continuous large deflection of
the slaving meter or large discrepancies between the magnetic compass
and the KI 525A compass card may
indicate a failure in the slaving system. If a slaving failure should occur,
the Slave/Free Switch should be
moved to select the free gyro mode.
Then, by using manual clockwise or
counterclockwise corrections, the
compass can be rotated to the correct heading as indicated on the
standby compass. The KCS 55A
system should continue to function
normally except the heading information will be solely derived from the
KG 102A Directional Gyro. There will
be no automatic heading correction
and periodic adjustments must be
made manually to correct for precession by reference to the standby
magnetic compass, as with any
directional gyro.
Note: It is desirable to disconnect the
autopilot under the following conditions:
1. HDG flag comes into view.
2. System is in fast slave.
3. During manual slaving.
The system has the capability to
supply the autopilot with an automatic disconnect signal under these
conditions.
Note: For system limitations in your
particular aircraft type, refer to your
Flight Manual Supplement.

KI 525A HSI makes it possible to intercept the course
smoothly, without overshooting or bracketing. One
method of doing this is to
adjust your heading so that
the top of the deviation bar
always touches the lubber

approaches the new course,
the deviation bar will swing

course. Notice that correction
for wind drift - in this case, a

course - is completely automatic as long as you keep the
deviation bar centered.
About midway between
Napoleon and Columbia

As you fly over the Columbia
station, the TO/FROM indicator changes to “FROM”. Since
the outbound course for V-12
from Columbia to Foristell
(FTZ) is 098°, you now set
the selected course pointer on
098° and fly to keep the deviation bar centered.
Near the Herman intersection
you switch to Foristell VORTAC and move the course
arrow to 100°, which is the V12 inbound course to FTZ.
The TO/FROM indicator
changes to “TO”.
Your clearance is V-12 to
Foristell, then V-14 to the St.
Louis (STL) VORTAC, direct
Lambert Field. Approaching
the FTZ station, the heading
bug is on 100° as a reference
for the V-12 course or as
heading command for the
autopilot, if used. Select the
St. Louis VORTAC on the NAV
receiver and set the course
pointer on the STL 062°
course.
As you cross the Foristell
VORTAC, the deviation bar
will align with the course
arrow. Now set the heading
bug to 062° and turn left to
follow V-14 to the STL VORTAC.
You are now established on

keep the deviation bar centered, correction for wind drift
will automatically be accomplished.

on the LOC deviation scale represents 1/2
degree of deviation when tuned to an ILS
frequency.

3. The KI 525A shows you that you have intercepted the localizer course. The glideslope
pointers have started to center, although
the display indicates your aircraft is still
below the glidepath at this point.
4. You are now centered on the localizer and
the glideslope. Once again, the KI 525A
shows your aircraft is crabbed about 5° to
the right to maintain the localizer course.
Note: For system limitations refer to your
Flight Manual Supplement.

If a back course approach is
required, it can be accomplished
as easily as a front course
approach. The course arrow
should always be set on the front
course inbound localizer course.
This will result is conventional pictorial deviation sensing even on
back course. The KI 525A display
gives you an accurate picture of
where you are at all times during
the approach and procedure turn.

1. You are outbound on the back localizer
course, having already set the course
pointer to the inbound front course at 238°.
The heading bug is preset at 193° for the
procedure turn. (Since there is usually no
glideslope signal on a back course, the
glideslope pointers are out of sight.)
2. During the procedure turn outbound, the
deviation bar shows pictorially that the aircraft (as represented by the symbolic aircraft in the center of the KI 525A) is flying
away from the localizer centerline at a 45°
angle when the heading bug is under the
lubber line. Note that left-right deviations of
the course bar give “fly-to” indicators, just
as on the front course.

3. Now you’ve reset the heading bug to 013°
and made a 180° turn to this heading. This
013° heading will intercept the back course.
The KI 525A clearly pictures the course you
are to intercept and the angle of interception.
4. You have smoothly intercepted the back
course. Since the course arrow is set on the
front course (238°), the KI 525A shows a
true picture of the situation - flying inbound
on the back course. You may reset the
heading bug to 058° for easy reference.

Autopilot Malfunction
An autopilot, autopilot trim or manual electric trim malfunction may be recognized as an uncommanded deviation in the airplane flight path or when there
is abnormal control wheel or trim wheel motion. The primary concern in reacting to an autopilot or trim malfunction, or to an automatic disconnect of the
autopilot, is in maintaining control of the airplane. Immediately grasp the control wheel and press and hold down the A/P DISC/TRIM INTER switch
throughout the recovery. Manipulate the controls as required to safely maintain operation of the airplane within all of its operating limitations.
CAUTION: Refer to the Airplane Flight Manual or the Airplane Flight Manual
Supplement for your particular aircraft for pertinent emergency procedures.
