move a waypoint on the co-
pilot’s EHSI, and any waypoint
created by the pilot can be
loaded only into the #1 RNAV
or #1 LNAV. Conversely, the
co-pilot’s joystick will not be
allowed to create or move a
waypoint on the pilot’s EHSI,
and any waypoint created by
the co-pilot can be loaded only
into the #2 RNAV or #2 LNAV.
RANGE RING
A light blue range ring located
half way between the center of
the symbolic aircraft and the out-
side of the map compass scale
aids in determining distance of
radar returns and/or position of
navaids in relation to the aircraft.
Off the right wing of the symbolic
aircraft, adjacent to the range
ring is the range ring distance.
The range ring represents half
the distance to the outer range
ring of the compass scale. The
available ranges, selectable from
the EFS 50 are 5, 10, 20, 40,
80,160, 240, 320 and 1000 nm.
Note: Systems which have the
RDR 1400 interfaced with the
EFS 50 will display weather
ranges of .5, 1 and 2 NM.
However, the NAV MAP fea-
ture is not supported on these
shorter ranges.
TEST, STBY and WX are the
only RDR 1400 mode annun-
ciation’s displayed on the
EHSI. Tilt and beacon infor-
mation is displayed only on the
RDR 1400 Control/Display
unit.

RADAR (IF EQUIPPED)
Refer to Figure 4.1.7 while
reviewing this section.
If a compatible ARINC 708
weather radar such as the
BENDIX/KING RDS series is
installed, weather information
may be selected for display.
When selected, weather informa-
tion will transparently overlay the
existing navigation data. Light
blue dotted lines represent the
weather radar scan limits.
Depending on the installation, the
EFS 50 may act as a weather
radar range controller or as a
simple remote display when the
EHSI has weather selected and
matches the radar range. As a
display only, if weather is select-
ed for display and the EHSI map
range does not match the select-
ed weather radar range “WX
FLT” will be annunciated in the
weather radar fault/warning posi-
tion. As a range controller, if the
selected range does not match
one allowed by the radar, “WX
FLT” will be annunciated in the
weather radar fault/warning posi-
tion. When the 1000 NM range
is selected “RANGE” is displayed
and the weather radar is placed
in standby. If the EFS 50 is the
only display media for the weath-
er radar, the radar will be placed
in standby when weather is not
selected for display.
Note: EHSI installations with
the BENDIX/KING RDS series
