BendixKing SG 465 System EFS 40/50 - Manual (Page 110)

EHSI Displays
when coupled with a simple
RNAV, such as the BENDIX/
KING KNS 81. The simplest
map data is provided by plotting
map symbols referenced to the
aircraft using bearing and dis-
tance from the select bearing
s e n s o r .
Beginning with software 10, spe-
cial waypoints without symbols
are accepted by the EFS which
may be used to display flight plan
legs without the waypoint sym-
bols at the connecting points.
These waypoints are supplied by
some LNAV
’ s for search pattern
flight plans.
Note: The following will address
only those areas of the EFS
40/50 map mode which are dif -
ferent from the standard com -
pass 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 w ith 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
the selected primary NAV sensor
is LNAV or enroute RNAV the
inbound “TO” course line is cyan
(green in approach mode). Any
time the cross-side sensor is
selected as the primary NAV
sensor the inbound “TO” course
line is yellow.
If the primary NAV sensor dis-
tance or bearing information
becomes invalid the NAV symbol
and course line will be removed.
“NO MAP” will be displayed to
alert the pilot that insufficient data
is present to calculate and plot
the primary NAV sensor map.
“NO MAP” will also be displayed
if the selected primary NAV sen-
sor, (e.g. ILS, ADF), does not
provide distance and bearing
information. The lateral deviation
scale will remain as long as valid
bearing or deviation information
is present.
