EHSI Displays
primary
NAV
sensor
is
sequenced through the LNAV
position. In previous software
releases, once the LNAV sensor
was displayed, its CRS or DTK
would become the selected
course, requiring the CRS to be
reset when another primary Nav
sensor was selected.
This change will allow an ILS
inbound course to be selected
prior to the completion of an
LNAV flight leg that will be fol-
lowed by an ILS approach.
In the event of a heading failure,
the course pointer head and tail
are removed and the course
deviation scale is fixed in a hori-
zontal position, providing stan-
dard course deviation information
(CDI) referenced to the digital
CRS selected. A RED X will be
drawn through the CRS annunci-
ation if there is a course select
knob failure. In the event the
selected course or desired track
received from the LN AV
becomes invalid, a RED X will
be drawn through the digital
r e a d o u t .
Note: The above heading failure
mode does not apply when
ADF is the primary NAV sen -
sor. (ADF D-Bar is heading
dependent and is non-opera -
tional without valid heading.)

LATERAL COURSE DEVIATION SCALE
The course deviation scale, two
white dots evenly spaced on both
sides of the symbolic aircraft,
provides a reference for the
course deviation bar to indicate
the center line of the selected
navigation or localizer course in
relation to the symbolic airplane.
The following represents the
deviation scale for different navi-
gation sources.
