INDICATOR (HSI)
SECTION 1
GENERAL
The Bendix/King KCS-55A Slaved Compass System with KI-
525A HSI Indicator is an additional navigation indicator option . The
KCS-55A compass system includes a slaving control and
compensator unit, magnetic slaving transmitter and a remote
directional gyro. The information obtained from the KCS-55A
compass system is displayed on the KI-525A Indicator.
The panel-mounted KI-525A indicator combines the display
functions of both the standard Directional Gyro (Heading Indicator)
and the Course Deviation Indicator's VOR/LOC/Glideslope
information to provide the pilot with a single visual presentation of
the complete horizontal navigation situation.
This system also incorporates a slaving accessory and
compensator unit. This unit indicates any difference between the
displayed heading and the magnetic heading. Up deflection
I
indicates a clockwise error of the compass card. Down deflection
indicates a counterclockwise error of the compass card. Whenever
the aircraft is in a turn and the compass card rotates, it is normal
for this meter to show a full deflection to one side or the other.
