12. The Glideslope pointers indicate the rela-
tive position of the Glideslope path with re-
spect to the aircraft. (In other words,
if
the
pointers are above the center marker, the air-
craft is below the Glideslope.)
Abnormal Circumstances
If
the Warning Flag (HDG) appears during
operation, the compass card indications will
be in error. Power ma be removed from the
KG 102A Directional iyro by pullin the ap-
propriate circuit breaker. The %elected
Course, VORlLOC Deviation Bar, the NAV
flag, and the TolFrom Indicator will remain in
operation.
If
the Navigation Warning Flag (NAV) ap-
pears during operation, there are several
possibilities: (1) the NAV receiver is not
turned on,
(2)
the NAV receiver is improperly
tuned,
(3)
the ground VOR or LOC station is
malfunctioning,
(4)
the aircraft is out of
range of the selected ground station.
(5)
the
aircraft NAV receiver has malfunctioned.
(The compass card will continue to display
the aircraft heading even
if
a usable NAV
signal is not being received.)
(6)
If
in RNAV
mode the DME has malfunctioned.
If
the Glideslope pointers remain out of
view during a front course ILS approach,
either the aircraft Glideslope receiver or the
round station Glideslope transmitter
is
mal-
able during a back course approach. (The
VOR
and
LOC
course display will continue to
function normally even
if
a usable Glideslope
signal is not being received.)
A continuous large deflection of the slaving
meter or large discrepancies between the
magnetic compass and the KI 525A compass
card may indicate a failure in the slaving
system.
If
a slaving failure should occur, the
ManlAuto switch should
be
moved
to
the Man
position
to
select the free gyro mode. Then,
by holding the CWlCCW switch to' the ap-
propriate side the compass card can be
rotated to the correct heading as indicated on
the standby compass. The KCS 55A system
should continue to function normally except
the heading information will
be
solely derived
from the KG 102A Directional Gyro; there will
be
no automatic heading correction and
periodic adjustments must be made manually
to correct for precession by reference
to
the
standby magnetic compass, as with any
directional gyro.

It is desirable to disconnect the au-
topilot under the following conditions
1
HDG flag comes into view
2 System is in Fast Slave
3
During manual slaving
The system has the capability to supply the
autopilot with an automatic disconnect signal
under these conditions
