EHSI Displays
Vertical Pointer Annunciation
for MLS A configuration option
added by software 08, allows the
choice of two pointer annuncia-
tions when an MLS is the select-
ed primary NAV sensor.

For a particular installation, refer
to the Aircraft Flight Manual Sup-
plement to determine the EFS
40/50 VNAV scale factors.
If invalid or failed glide slope or
VNAV data is received, the verti-
cal deviation bar and scale are
removed and replaced with a
RED X annunciation.
Beginning with software 09, the
vertical deviation bar and scale
are decluttered without displaying
a RED X when the deviation
information is provided in ARINC
429 format with a status of NO
COMPUTED DATA (NCD). The
RED X is still displayed for invalid
or missing data.
WIND VECTOR
o
When the aircraft is equipped
with the appropriate LNAV equip-
ment, an optional full time wind
vector indicating approximate
wind direction and speed may be
displayed in white in the upper
left corner below the selected
course. Wind vector information
will be available only when valid
data is provided by the LNAV.
The information provided by this
vector is advisory only. It is NOT
intended for use during approach
as critical flight data because it
will become inaccurate during
altitude changes.
In single LNAV systems the wind
vector data may be displayed on
all EHSI displays. In dual LNAV
installations with an LNAV select-
ed as the primary nav source,
that LNAV is the only source of
wind vector data. In dual LNAV
installations with a primary nav
source other than an LNAV, the
wind vector data will be supplied
only by the on-side LNAV with
software prior to 08, but begin-
ning with SW 08, the off-side
LNAV is used as a secondary
source of wind vector informa-
t i o n .
N o t e : If the selected LNAV is
configured as a Crouzet
Omega, the wind vector will be
dis played as the standard
meteorological wind symbol.
DRIFT ANGLE POINTER
( LNAV only)
The drift angle pointer is an
optional hollow cyan (green or
yellow in approach mode) trian-
gular pointer which is generated
by some LNAVs and rotates
about the outside of the compass
scale. Referenced to the lubber
line, the drift angle pointer repre-
sents drift angle left or right of the
aircraft heading. With respect to
the compass scale, the drift
angle pointer represents aircraft
actual ground track.
o
The optional drift angle pointer
may be displayed only when the
LNAV is selected as the primary
NAV source and valid information
