Slaving Meter

This meter indicates any
difference between the displayed heading
and the magnetic heading. Right or up
deflection indicates a clockwise error of the
compass card. Left or down deflection indi-
cates a counterclockwise error of the com-
pass card. Whenever the aircraft is in a turn
and the card rotates, it is normal for this
meter to show a full deflection to one side or
the other.
NOTE: During level flight it is normal for
the meter needle to continuously move from
side to side and to be fully deflected during a
turn. If the needle stays fully deflected, left or
right, during level flight, the free gyro mode
can be used to center it, as described below.
Slave and Free Gyro Switch

The KA 51 B Slaving Control and
Compensator Unit is a smaller slaving acces-
sory which can be used in installations where
panel space is limited. The KA 518 can be
mounted either vertically or horizontally, and
provides all the slaving modes and capabili-
ties of the larger KA 51A.
