radar provide dual range
selection by allowing the radar
indicator and EHSI or dual
EHSIs to select independent
ranges. Only one source of
radar mode, tilt and gain is
supported. When the ranges
selected on the two controlling
indicators do not match, the
weather presentation will be
updated on alternating sweeps
of the radar antenna. Exam-
ple: if pilot’s EHSI is updated
on the right sweep then the
radar indicator will be updated
on the left sweep or vice versa.

In installations capable of pro-
viding weather information on
three displays, the display
without radar range control
must match one of the control-
ling displays in order to pre-
sent weather. If the range
does not match, “WX FLT” will
be annunciated in the weather
radar fault/warning position.

Four data lines are reserved
below the primary NAV sensor
source annunciator to display
radar information. The first line
displays special performance
feature annunciations such as
ARL (automatic range limiting).
The second line annunciates the
standard radar modes WX, WXA
or MAP. The third line provides a
digital readout of tilt angle dis-
played in tenths of a degree pre-
ceded by an arrow pointing up or
down to indicate tilt direction. If
Auto Tilt is activated, an “A” will
follow the tilt arrow. The fourth
line will display radar faults and

warnings. The radar faults are
prioritized. When more than one
fault occurs the one with the
highest priority will be displayed.

TRACK LINE

A yellow dashed line, originating
at the symbolic aircraft and
extending to the edge of the
compass card, appears on the
weather display when either the
track left or track right button is
pressed on the radar control
panel. The track line will be auto-
matically removed within 15 sec-
onds after the button is released.

LIGHTNING DETECTION

Up to 63 grey colored lightning
cell symbols can be displayed on
the EHSI or MFD displays when
provided by a compatable light-
ning sensor. Unlike weather
radar information, lightning data
may be presented in all 360
degrees of display area. Range
selection for all lightning data dis-
played on EFS is controlled by
the EFS control panel. The EFS
will display the following symbols
depicting three different levels of
lightning intensity:

Lightning information will only be
displayed while weather is select-
ed for display on the EFS. Some
versions of Radar Control Panels
(RCP) have a lightning select
