Until power is applied to the KCS 55A
System, and the directional gyro is up to
speed, a red flag labeled 'HDG' will be
visible in the upper right quadrant of the
KI 525A Indicator. In operation, this warn-
ing flag will be visible whenever the power
being supplied is inadequate or the gyro
is not up to speed.
With the application of power to the KCS
55A System, and gyro up to operating
speed, the red 'HDG' flag should disap-
pear from view.
If the KCS 55A System is in the slaved
gyro mode, the compass card will aut@
matically fast slave at the rate of 180
degrees per minute toward the aircraft's
magnetic heading. (Immediately after
applying power, this compass card move-
ment should be quite visible.) It will con-
tinue to fast slave until the proper magnet-
ic heading is indicated, after which it will
slave at a constant rate of 3 degrees per
minute to keep the system aligned with
the earth's magnetic field.
Under some conditions it is possible for
the system to stop slaving exactly 180
degrees from the correct heading. If this
should occur, move the 'Slave' switch on
the KA 51A or KA 518 to the unslaved
(free) position. Rotate the compass card
+lo
degrees from the incorrect heading
by using the manual rotation switch and
then return the system to slaved opera-
tion. The system will then slave to the cor-
rect heading.
For free gyro operation, check the mag-
netic compass to determine the correct
magnetic heading. Then use the manual
slave switch to align the system with the
earth's magnetic field. Periodic checks
with the standby compass are recom-
mended to check and correct for gyro
precession.

Until a usable navigation signal is being
received by the NAV system, a red flag
labeled "NAV will be visible in the upper
left quadrant of the KI 525A Indicator. In
operation, this warning flag should be visi-
ble whenever an inadequate navigation
signal is being received.
For normal navigation to or from a VOR or
VORTAC, set the NAV receiver to the
desired VOR or VORTAC frequency and
the red navigation flag (NAV) should dis-
appear from view if a usable signal is
being received.
Rotate the course select knob to position
the course pointer to the desired VOR
course.
The VOR deviation bar represents the
selected course, and the relationship of
this bar to the symbolic aircraft in the cen-
ter of the instrument visually presents the
actual relationship of the selected course
to your aircraft heading. (In other words, if
the symbolic aircraft on the display indi-
cates approaching the deviation bar at 45
degrees, that is the angle at which your
aircraft is actually approaching the select-
ed course.)
T o prepare for an ILS approach, tune the
NAV receiver to the desired Localizer fre-
quency. If a usable Localizer signal is
being received, the NAV warning flag will
disappear.
For a front or back course approach,
rotate the course select knob to set the
course pointer on the inbound Localizer
course.
As with normal navigation (#6
above), the LOC deviation bar represents
the desired Ccjurse. The relationship
between this bar and the symbolic aircraft
gives a true picture of your aircraft's posi-
tion with respect to the Localizer course.
Always setting the course pointer to the
inbound Localizer course provides the
correct deviation bar sensing whether fly-
ing a front or back course approach.
