Attitude Flag -Warns that the
displayed attitude information is
invalid, due either to a malfunctioning
remote vertical gyro
or
KCI
31
OIA atti-
tude power supply, or to a fault in the
servo
loop.
10.
Test Pushbutton
-
Initiates self-
test of the Flight Command Indicator
and Pictorial Navigation Indicator.
See Preflight Test/Startup Procedures
for details.
11.
Vertical Navigation Track Angle
Annunciator (ANG) -When illumina-
ted, indicates that the vertical naviga-
tion indicator is displaying the track
angle necessary to reach the current
VNAV waypoint. When extinguished,
indicates that the display shows linear
altitude deviation from the selected
VNAV track.
12.
Vertical Navigation Pointer
-
Displays vertical navigation track
angle or altitude deviation with re-
spect to the Vertical Navigation Scale.
The VNAV
Off
Flag swings into view
when the KNS
660
determines that
the VNAV computation is invalid.
13.
Vertical Navigation Scale
-
Measures displacement
of
the Verti-
cal Navigation Pointer. With the ANG
annunciator illuminated, full-scale
deflection indicates a plus or minus
5O
vertical track angle, with each scale
marker indicating one degree.
With the ANG annunciator extin-
guished and the KNS
660
engaged in
the RNV ENR mode, full-scale devia-
tion indicates the aircraft is
1000
feet
above or below the appropriate alti-
tude for the flight path being tracked,
with each scale increment
209
feet of
altitude deviation.
When the KNS
660
is engaged in the RNV APR
mode,
full-scale deflection indicates
500
feet
of deviation, and each incremental
marker indicates
100
feet.
14.
Computer Flag -Warns that the
displayed steering command is inval-
id, due to malfunction
of
the
KCI
31
O/As
command bar power
supply or drive mechanism,
or
to
internal failure of the KCP
420
Flight
Computer. The KFC
400
automati-
cally disengages autopilot and flight
director functions when the detected
malfunction is within the KCP
420,
but
not when the KCI
31
O/A is at fault.
15.
Expanded Localizer
Scale
-
Measures course deviations displayed
by the Expanded Localizer Pointer.
16.
Expanded Localizer Pointer
-
Indicates angular deviation from
localizer centerline with reference to
the scale markers.
17.
Inclinometer
-
Displays aircraft
slipping or skidding motions during
maneuvers
or
flight in turbulence.
18.
Vertical Navigation Flag
-
Warns
.
that VNAV angle or deviation display
is not valid.
19.
Expanded Localizer Flag
-
Warns that a localizer frequency is not
tuned, or that the localizer signal is
not valid.
20.
Glideslope Flag -Warns that
glideslope display is not valid.
