EHSI Displays
LATERAL COURSE
DEVIATION BAR
The course deviation bar repre-
sents the center line of the
selected navigation or localizer
c o u r s e .
If invalid or failed primary NAV
sensor data is received the
course deviation bar and scale
are removed and a RED X
a n n u n c i a t e d .
Beginning with software 09, the
deviation bar and scale are
decluttered without displaying a
RED X when the deviation infor-
mation is provided in ARINC 429
format with a status of NO COM-
PUTED DATA (NCD). The RED
X will still be displayed if the data
is missing or invalid.
TO/FROM INDICATOR
A white filled triangle near the
center of the EHSI pointing
toward the head (“TO”) or tail
(“FROM”) of the course pointer
indicates whether the selected
course is TO or FROM the sta-
tion or waypoint. The TO/FROM
annunciator is not displayed dur-
ing ILS/MLS operation or when
an invalid NAV signal is received.
D I S TANCE, GROUNDSPEED
and TIME-TO - S TAT I O N
The EFS 40/50 provides up to
three distance displays — one
for each selected navigation
source (if distance information is
available from that source).
The readout for the primary NAV
source is shown in the upper
right corner. This readout will
also show aircraft groundspeed
and Time-to-Station/Waypoint.
Both are displayed simultaneous-
ly with software 08 and higher.
The distance readout for naviga-
tion source 1 (the single-bar
bearing pointer) is in the lower
left corner below the navigation
source annunciator. The readout
for navigation source 2 (the dou-
ble-bar bearing pointer) is in the
lower right corner below the navi-
gation source annunciator.
These readouts show distance
(in nautical miles) to the selected
station when in VOR, TACAN,
ILS or MLS mode. When in
LNAV, RNAV or GPS mode, dis-
tance to the waypoint is shown.
Each of these three distance
readouts is displayed in the same
color as the source annunciator
and pointer with which it is asso-
c i a t e d .
With software 04/05/06/07 the
E F S 40/50 will display ground
speed up to 999 KTS, Time-To-
Station up to 511 minutes and
distance up to 4,095 nautical
miles. In most cases, the DME
will be the limiting factor in dis-
playable data.
With software 08 and higher, the
E F S 40/50 will display ground
speed up to 999 KTS, Time-To-
Station up to 8:31 (H:MM univer-
sal format) and distance up to
4,095 nautical miles. Time-To-
Station is displayed immediately
below and at the same time as
