BendixKing SG 465 System EFS 50 - Manual (Page 101)

EADI Displays
4.2.7 Issued 4/95 SW 06/07/08/11
pilot that back course information
is being displayed. Refer to Fig-
ure 4.2.3 and 4.2.4.
Software version 07 and higher
will display the expanded
LOC/MLS scale as three dots.
Note: Warning, some conven-
tional ADI expanded ILS and
MLS displays represent 1/4 of
the full scale displayed by the
HSI. The EFS 50 provides 1/2
the EHSI displayed deviation
to provide better pilot interface.
RISING RUNWAY
Three configuration options are
selectable at the time of installa-
tion and certification for display of
the rising runway symbol.
❏ The first option provides full
time display of the rising runway
only when in the precision
approach mode. The symbolic
rising runway will be displayed in
the lower center of the display
just above the LOC/MLS lateral
deviation scale. The center line
of the symbolic rising runway rep-
resents ILS or MLS fly to com-
mand. If the radio altimeter pro-
vides height above the ground
information to the EFS 50, the
rising runway symbol will start
increasing in size at 200 feet and
will continue to increase in size to
0 feet. When the on-side ILS or
MLS is selected as the primary
NAV sensor, the rising runway
will be green in color. If the off-
side sensor is selected, the run-
way will change to yellow, alert-
ing the pilot that he has selected
off-side information.
❏ A second configuration option
provides for the display of a tradi-
tional deviation bar in place of the
rising runway. The deviation bar
will overlay the lateral deviation
scale. It will not be positioned
just above the deviation scale as
the rising runway is.
❏ A third configuration option
allows the display of the rising
runway unless one of the follow-
ing conditions exists, in which
case the deviation bar will be dis-
played.
• No radio altimeter
• Radio altimeter is not being
displayed, above 2,500 feet or
not providing computed data
• Radio altimeter is below mini-
mum altitude, white dashes
displayed
• Radio altimeter is flagged, RED
dashes displayed.
In the event the lateral deviation
information becomes invalid or
failed, the rising runway or D bar
and lateral deviation scale are
removed, the lateral deviation
scale is replaced with a RED “X.”
Software version 07 replaces the
5 dot expanded localizer scale
with a 3 dot expanded localizer
scale whenever the rising runway
is displayed.
