SECTION I
GENERAL INFORMATION
1.1 SYSTEM COMPONENT DESCRIPTION
The KCS 55/55A Pictorial Navigation System is composed of five units: KI 525/525A Pictorial
Navigation Indicator, KG 102/102A Directional Gyro, KMT 112 Magnetic Azimuth Transmitter, KA
51/51A/51B Slaving Accessory, and the KA 52 and KA 57 Autopilot Adapters, if required.
The KI 525/525A Pictorial Navigation Indicator provides a pictorial display of the horizontal navi-
gation situation. The KI 525/525A also provides manual controls for course and heading datum
selections. Outputs from the KI 525/525A are for automatic pilot or flight director, VOR receivers
and additional compass loads.
The KG 102/102A Directional Gyro is a remote mounted unit which, in conjunction with the KMT
112 Magnetic Azimuth Transmitter, provides a gyro-stabilized magnetic heading to the KI 525/
525A Indicator. In addition to the slaving circuitry this unit contains an internal power supply which
provides excitation voltages for the Magnetic Azimuth Transmitter and positive and negative D.C.
voltages for the Pictorial Navigation Indicator and the Slaving Accessory.
The KMT 112 Magnetic Azimuth Transmitter senses the direction of the earths magnetic field and
transmits this information to the Pictorial Navigation Indicator.
The KA 51/51A/51B Slaving Accessory is a panel mounted unit which contains the slaving meter,
slaving switches, and corrector circuitry which compensates for the effect of local magnetic distur-
bances on the Magnetic Azimuth Transmitter.
The KA 52 Autopilot Adapter is an optional remote mounted device that converts the DC heading
and course datum signals from the Pictorial Navigation Indicator into two separate AC signals
compatible with certain autopilot systems.
The KA 57 Autopilot Adapter is an optional remote mounted device that converts the DC heading
and course datum signals from the KI 525/525A Indicator into a single, switchable AC output sig-
nal compatible with certain autopilot systems.
1.2 FUNCTIONAL
(KCS 55 System)
When power is first applied to the KCS 55 System, and the system is in the slaved gyro mode, the
heading display will automatically fast slave at the rate of 180 degrees per minute to align the slav-
ing control transformer in the KI 525 with the magnetic heading transmitted by the KMT 112. The
system will remain in this fast slave mode for 120 seconds after which it will automatically revert
to the normal slaving mode and slave at a constant rate of 3 degrees per minute to keep the sys-
tem aligned with the earth’s magnetic field. If the system is cycled from the free gyro mode to the
slaved gyro mode by means of actuating the "slave in" button on the KA 51 the "fast slave" will
automatically be repeated.
(KCS 55A System)
When power is first applied to the KCS 55A System, and the system is in the slaved gyro mode,
the heading display will automatically fast slave at the rate of 180 degrees per minute to align the
slaving control transformer in the KI 525A with the magnetic heading transmitted by the KMT 112.
The system will remain in this fast slave mode until the slaving error is reduced to zero and then
revert to the normal slaving mode and slave at a constant rate of 3 degrees per minute to keep
the system aligned with the earth’s magnetic field. If the system is cycled from the free gyro mode
to the slaved gyro mode by means of actuating the "slave in" button on the KA 51A (toggle switch-
es on the KA 51B), the "fast slave" will automatically be repeated.

The tumble detect version, (KG 102A, P/N 060-0015-02), while in slaved gyro mode will automat-
ically switch the system to fast slave mode when rates exceed approximately 25 degrees per sec-
ond. Once the system display (KI 525/525A) matches earth’s magnetic field +/- 2 degrees, the
system will revert back to slow slave mode.
Stabilized heading information is supplied to the KI 525/525A by the KG 102/102A. When in the
slaved gyro mode this heading signal, which may vary at rates up to 30 degrees/second, is
summed with the normal slaving signal from the KMT 112 to provide the final drive signal for the
heading display.
When the system is in the free gyro mode the heading signal from the KG102/102A is the only
input to the heading display drive. While in the free gyro mode the pilot may command changes
in the displayed heading by means of depressing the clockwise or counterclockwise push buttons
on the KA 51/51A (toggle switches on the KA 51B).

The KI 525/525A is an internally lighted unit that displays a gyro-stabilized aircraft magnetic head-
ing, selected course, selected heading. VOR and localizer course deviation, glideslope deviation
and a TO-FROM indication for VOR flight.
In addition, warning flags are provided to signify unusable VOR/Localizer information (NAV Flag)
and to indicate a valid compass system (HDG Flag). The glideslope pointer will retract from view
when an unusable glideslope signal is being received.
A bootstrap heading synchro is provided as a source of slaved heading information, and heading
and course select transducers provide DC signals for autopilot or flight direction information. Ei-
ther of two types of course resolver is provided depending on which part number unit is chosen.
All part numbers are capable of operating at 30Hz. However, 066-03046-02/03/06/07/11/12 are
capable of operating at either 30Hz or 400Hz. Serial number 43434 and above have glideslope
damping for helicopters in all versions.

1.4.2 KG 102/102A DIRECTIONAL GYRO
The KG 102/102A Directional Gyro is a remote mounted unit which, in conjunction with the KMT
112 Magnetic Azimuth Transmitter, provides a gyro stabilized magnetic heading to the KI 525/
525A Indicator. In addition to the slaving circuitry the KG 102/102A contains an internal power
supply which provides gyro rotor power, excitation voltages for the Magnetic Azimuth Transmitter,
and positive and negative D.C. voltages for the Pictorial Navigation Indicator and the Slaving Ac-
cessory.
PN 060-0011-00 is the only version available for the KG 102. The KG 102A is available in a stan-
dard version (PN 060-0015-00), a version with RFI filter (PN 060-0015-01), and a version with RFI
filter and tumble detection (PN 060-0015-02).
1.4.3 KMT 112 MAGNETIC AZIMUTH TRANSMITTER
The KMT 112 (PN 071-1052-00) senses the direction of the earth’s magnetic field and transmits
this information to the KI 525/525A.

The KA 51 Slaving Accessory (PN 071-1053-00) is a panel mounted unit that displays the slaving
error between the KMT 112 and the KI 525 by means of a small meter movement.
The KA 51A/51B Slaving Accessory is an internally lighted panel mounted unit that displays the
slaving error between the KMT 112 and KI 525A by means of a small meter movement.
KA 51A, three pushbutton switches are provided below the slaving meter. The center switch is an
alternate action switch that engages the "slaved gyro" mode when depressed. When the switch
is in its outer position the KCS 55/55A is in the "free gyro" mode. The other two pushbutton switch-
es are momentary switches and provide clockwise and counterclockwise manual slaving whenev-
er the system is in the "free gyro" mode.
The KA 51/51A also contains circuitry through which hard-iron effects upon the KMT 112 can be
compensated by the adjustment of two potentiometers. Access holes labeled N/S and E/W are
provided on the front surface of the KA 51/51A for access to these two potentiometers.
The KA 51B, houses two toggle switches below the slaving meter. The switch nearest the meter
(SLAVE/FREE) is a lockout type toggle switch that engages the slaved gyro mode when in the
slave position and places the KCS 55A/KCS 305 in the free gyro mode when in the free position.
The lower switch (CW/CCW) is a momentary left and right toggle switch and provides clockwise
and counterclockwise manual slewing whenever the system is in the free gyro mode.
The KA 51B also contains circuitry through which hard iron effects upon the KMT 112 can be com-
pensated by the adjustment of two potentiometers. Access holes labeled N/S and E/W are pro-
vided on the side of the unit for access to the two potentiometers.

1.4.5 KA 52 AUTOPILOT ADAPTER
The KA 52 Autopilot Adapter is an optional remote mounted device that converts the DC heading
and course datum signals from the KI 525/525A Indicator into two separate AC signals compatible
with certain autopilot systems. PN 071-1055-00 is the standard version. PN 071-1055-01 is avail-
able when 115 V 400 Hz ref. is needed by Radar for Stabilization.
1.4.6 KA 57 AUTOPILOT ADAPTER
The KA 57 Autopilot Adapter (PN 071-0017-00) is an optional remote mounted device that con-
verts the DC heading and course datum signals from the KI 525/525A Indicator into a single, swit-
chable AC output signal compatible with certain autopilot systems.
