360 MAP DISPLAYS
Refer to Figures. 4.1.7 and 4.1.8
while reviewing 360 MAP DIS-
PLAYS.
The EFS 50 provides two basic
map formats, a 360-degree map
display about the aircraft and an
approximately 85-degree sec-
tored map display in front of the
aircraft. Information which may
be displayed includes waypoints,
navaids, airports and weather
radar information. The type and
amount of data presented on the
map will depend on the interfac-
ing equipment. When coupled
with a compatible LNAV, such as
the BENDIX/KING KNS 660, the
EHSI can show up to 15 map
symbols. These will include all
flight plan waypoints that are
within the selected display range.
In addition, the pilot can choose
to display either navaids or air-
ports that are located off the
flight-planned route. Up to 10
navaids or up to 10 airports can
be displayed as long as the total
number of map symbols does not
exceed 15.
In addition to the above, the #1
and #2 bearing pointers can be
overlayed to indicate the direction
and distance to two additional
navaids or waypoints.
Note: The following will
address only those areas of
the EFS 50 map mode which
are different from the standard
compass presentations.
All map presentations provide
a traditional CDI display.
MAP 360 COMPASS CARD
The operation of the compass
card remains the same in the
Map mode as in the standard
EHSI display. However, the out-
side of the compass card now
performs a secondary function by
becoming the outer range ring for
the Map display.
SELECTED COURSE
The alphanumeric course select
readout in the upper left corner of
the display functions the same in
the map mode as in the standard
EHSI mode. The standard EHSI
selected course pointer, to/from
pointer, deviation bar and devia-
tion scale are removed from with-
in the compass card display.
When the primary NAV sensor
provides distance and bearing
information the selected course
pointer is replaced with the
course line. If the primary NAV
sensor “TO” or “FROM” waypoint
or VOR is within the selected
map range, a movable course
line is drawn through its center.
As the selected course is
changed, the course line will
rotate about the referenced point.
If the selected primary NAV sen-
sor is an approach on-side sen-
sor, the inbound “TO” course line
is green and the outbound
“FROM” course line is white. If
