selected heading. In addition to
the digital display, on the heading
tape is a hollow orange heading
bug which provides a visual cue
of the selected heading with ref-
erence to the aircraft heading.
Note: As the aircraft heading
changes, the selected course
pointer and heading bug will
follow the heading tape and
may disappear from view. The
heading bug and course point-
er function the same as they
do in the normal mode of oper-
ation, once set they are fixed
to the heading tape or com-
pass card.
NAVIGATION SOURCE
ANNUNCIATION
A vertical three- or four-letter
alphanumeric readout located on
the left or right side of the dis-
play, depending on vertical scale
side selection, indicates the navi-
gation selected as the primary
navigation sensor.
Green annunciations indicate an
on-side approach NAV system is
being displayed. Yellow indi-
cates the cross-side system has
been selected. Cyan annuncia-
tions apply to on-side non-
approach NAV systems. These
color codes apply to the NAV
source annunciator, CRS pointer,
deviation bar, CRS, and dis-
tance.
If both sides select the same
navigation source (i.e., pilot and
copilot select VOR 2) a yellow
box is placed around the naviga-
tion source annunciator on both
sides of the cockpit.
If both sides select their respec-
tive cross-side navigation source
(i.e., pilot selects system 2, copi-
lot selects system 1) then both
NAV source annunciators will be
yellow with no yellow box.
LATERAL COURSE
DEVIATION SCALE
(Non Approach Mode)
Located at the bottom center of
the EADI, displayed in white, with
four hollow circles and a center
diamond is the lateral deviation
scale. The course deviation
scale provides a reference for the
course deviation bar to indicate
the centerline of the selected
navigation or localizer or MLS
course in relation to the center
diamond.
The course width displayed in the
composite mode is identical to
that typically shown on the EHSI.
LATERAL COURSE
DEVIATION BAR
The course deviation bar repre-
sents the centerline of the select-
ed navigation or localizer course.
If invalid or failed primary NAV
sensor data is received the
course deviation bar and scale
are removed and a RED X
annunciated.
