mation to the EFIS and each Flight
Computer.The Free/Slave switch
allows the pilot to select either Free
or Slaved Magnetic Heading mode.
The slew switch is utilized for manu-
ally correcting heading information
during flight operations at higher lati-
tudes.
Note: In systems with copilot EFIS,
the secondary KCS 305 system
interfaces with the secondary KCP
520.
KRG 333 Rate/Acceleration
Sensor
Dual KRG 333 are used to supply
three axis rate/two axis acceleration
sensor inputs to each Flight
Computer for command calculation
and monitoring.
Control PositionTransducer
Each control axis (pitch, roll, yaw,
and collective) has a control position
transducer (synchro resolver) to
feedback control position to both
Flight Computers.
KAD 480 Air Data System
The KAD 480 Digital Air Data
System is comprised of the KDC
481T Central Air Data Computer, the
KAV 485 Altimeter/Vertical Speed
Indicator, and a temperature probe.
KDC 481T Air Data Computer
The heart of the KAD 480 Air Data
System, the KDC 481T Central Air
Data Computer, processes pitot and
static pressures and air temperature
inputs, and supplies the processed
information to both KCP 520 Flight
Computers and the KAV 485
Altimeter/Vertical Speed Indicator.
The KDC 481T uses a strap module
which contains aircraft specific infor-
mation required for overspeed pro-
tection, etc. The Central Air Data
Computer is also capable of supply-
ing air data information to optional
Navigation Management Systems.
