KCS 305 SLAVED COMPASS
SYSTEM
The KCS 305 system is comprised of
the KSG 105 Directional Gyro, the
KA 51B Slaving Accessory, and the
KMT 112 Flux Valve. The slaved
compass system provides directional
information to the EFIS Symbol
Generator and the Flight Computer.
The Free/Slave switch provides
the pilot a means to manually
compensate for magnetic effects in
the vicinity of the Flux Valve. The
switch allows the pilot to select either
Free or Slaved Magnetic Heading
mode. The slew switch is also
utilized for manually correcting
heading information during flight
operations at higher latitudes.
The Magnetic Slaving Unit, often
referred to as the flux valve, is
remotely mounted in the tailboom to
sense the earth’s magnetic field
directions. By sensing the variation in
the earth’s magnetic fields, the slaving
unit can correct the Directional Gyro
for precession error.
KRG 332 YAW RATE GYRO
The KRG 332 is a remote mounted
rate gyroscope used to provide yaw
rate information to the Flight
Computer and EFS 40 Symbol
Generator. The Symbol Generator
displays rate of turn on the EADI.
KAB 330 TRIAXIAL ACCELEROM-
ETER
The KAB 330 is a three-axis
accelerometer sensor that provides
acceleration inputs to the Flight
Computer for command calculation
and monitoring.
CONTROL POSITION TRANS-
DUCER
Each control axis (pitch, roll, yaw,
and collective) has a control position
transducer to feedback control posi-
tion to the Flight Computer.
