Fault Annunciations
only be used as supplementary
i n f o r m a t i o n .
A large RED “SG” appearing on
a black display annunciates a
Symbol Generator failure which
would result in processed data
that is unusable for navigation.
RAW DATA DEVIATION
ANNUNCIATIONS
Pointer/Scale malfunctions are
annunciated by removal of the
associated pointer/scale and
placing a RED X drawn in their
place. A flag presented on the
vertical deviation scale will result
in the deviation pointer being
removed. On the EH SI, the
pointer/scale annunciations
include lateral deviation, GS or
VN and fore/aft in Doppler and
homing mode. On the EADI, the
scale annunciations include later-
al deviation and GS or VN. Refer
to figure 6.1 for display presenta-
tions showing these annuncia-
t i o n s .
Beginning with software 09, both
lateral and vertical deviation bars
and scales are decluttered with-
out displaying a RED X when the
deviation information is provided
in ARINC 429 format with a sta-
tus of No Computed Data (NCD).
The RED X is still displayed for
invalid or missing data.

BEARING POINTER
A N N U N C I A T I O N S
Bearing pointer source failure or
invalid data or No Computed
Data (NCD) causes a RED X to
be drawn through the source
annunciator. The bearing pointer
or NAVAID symbol is also
removed.
w
ALPHANUMERIC READOUT
A N N U N C I A T I O N S
Failures affecting alphanumeric
readouts are annunciated by a
RED X drawn through the read-
out. On the EHSI (figure 6.1), the
alphanumeric readouts include
NAV bearing pointer source and
course (CRS) or desired track
( D T K ) .
Failures affecting distance infor-
mation are annunciated by RED
dashes in the data field. When
the Distance Source is opera-
tional but not providing valid dis-
tance data (no lock on or NCD)
dashes the color of the sensor
will be placed in the data field.
Speed (KT) and time (MN)
annunciation will be removed if
valid distance, speed and time-
to-station information is not pro-
vided by the primary NAV sensor
s y s t e m .
Failures affecting radio altimeter
information are annunciated by
RED dashes in the data field on
the EADI. When the radio
altimeter source is operational
but not providing valid data (no
lock on or NCD) white dashes
will be placed in the data field.
Refer to Figure 6.4.

CHECK CONFIG
A yellow “CH ECK CONFIG”
message will display in the upper
right corner of the EHSI and
