EHSI Displays
MAP COURSE
DEVIATION INDICATOR
A stationary white scale along
the bottom center of the display
provides reference for the course
deviation bar to indicate the posi-
tion of the aircraft in relation to
the selected navigation course.
This course scale provides a
conventional CDI (course devia-
tion indicator) presentation.
When LOC is selected while in a
map mode, Back Course annun-
ciation and CDI needle reversal
is provided when the selected
course is 105 degrees from the
aircraft heading (results in a fly to
situation). “BC”, in green, (yellow
“BC” if cross-side sensor is
selected) is annunciated left of
center on the lateral deviation .
TO/FROM
To the right of the alphanumeric
Course Select a white “TO” or
“FR” will replace the standard
EHSI TO/FROM pointer when in
non-ILS map modes.
BEARING POINTER
While in the map modes stan-
dard EHSI bearing pointers are
displayed when the selected
bearing source does not have
distance associated with it or
when the distance is greater than
the selected map distance. Once
the bearing source falls within
display distance the bearing
pointer is removed and the asso-
ciated map symbol is displayed.
The #1 system map symbol will
be displayed in light blue and the
#2 will be displayed in magenta
as are the standard bearing
pointers. If bearing or distance
information becomes invalid, the
map symbol will be removed. If
only the distance information
becomes invalid, the map symbol
will be removed and replaced
with the standard bearing pointer.
Note: See BEARING POINTER,
under STANDARD EHSI DIS -
PLAYS in this section for
details on the display of Mag -
netic bearing pointers when
the compass card is True ref -
erenced and the display of
True bearing pointers when
the compass card is magnetic
referenced.
REFERENCE WAYPOINT
When the joystick is interfaced to
an EFS 40/50 system, it can be
used to generate and move a
single Reference Waypoint on
the display unit. This reference
waypoint can then be entered
into the KNS 81, KNS 660, KLN
88, or any other LNAV using an
appropriate GAMA 429 inter-
face. The KNS 81 must have
the graphic output bus.
With an LNAV, RNAV, (or KNS
81 configured as a NAV) select-
ed for the primary nav sensor
and during display of a NAV MAP
on the EHSI, initial movement of
the joystick will create a refer-
ence waypoint ahead of the air-
craft on the half range ring at the
current heading. This will be true
for both HSI and ARC map dis-
