SYSTEMS DESCRIPTION
KCS 55A Compass System provides the pilot with a visual
display of the aircraft's heading and position in relation to a
desired course. The KCS 55A includes a magnetic slaving
transmitter, a slaving control and compensator unit, a
directional gyro for stabilization of the system and the Pictorial
Navigation Indicator. The KI 525A combines the display
functions of the standard Directional Gyro with VOWLOC
course deviation indication and Glideslope deviation and flag.
The KI 525A Pictorial Navigation Indicator is the panel display
for the KCS 55A compass system combining the display
functions of the standard Directional Gyro, the VOR and LOC
deviation indicator with Glideslope display. The KA 51A
Slaving Control and Compensator Unit provides selecting the
“slaved gyro” or “free gyro” modes. The unit also contains a
meter which indicates difference between the KI 525A
compass card and the aircraft’s magnetic heading. The KMT
112 Magnetic Slaving Transmitter senses the direction of the
earth’s magnetic field and transmits this information through
the slaving circuitry to the Directional Gyro which is
automatically corrected for precession or “drift”. The KG 102A
Directional Gyro provides gyro-stabilization for the system and
contains the slaving circuitry. When power is applied to the
KCS 55 System the PWR flag will disappear from view if the
power is normal. If the system is in the slaved gyro mode the
