WX1000STORMSCOPE
(OPTIONAL)
The
Stormscope system is a passive
radar
system
; that is, it does not
transmit energy . Instead, the
Stormscope detects electrical discharges
(lightning) from convective
clouds through passive reception of their
energy and displays them as a
moving map on a cathode ray tube
(CRT) . Since the Stormscope system
does not plot water droplets like
regular weather radar, it
is not subject to attenuation .
The Stormscope
is located in the
instrument panel and is coupled
to the copilot's atti-
tude/heading
computer so that the
Stormscope map will automatical-
ly
reposition thunderstorm information
relative to aircraft heading .
The Stormscope
system includes an antenna,
a receiver/processor
unit,
cathode ray tube (CRT) display,
and associated aircraft wiring .
The
Stormscope receives 28
VDC through the 2-amp STORMSCOPE
circuit breaker on the
copilot's circuit breaker panel .
CAUTION
The Stormscope
should never be used to
attempt
thunderstorm
penetration . Thunderstorm
avoid-
ance
must not be solely predicated
upon the use of
the Stormscope .
The
following information is meant as a
familiarization only to the
WX1000
Stormscope system . Refer to the "Stormscope
Series 11 Pilot's
Handbook"
for additional information and
operating instructions .

MODES, VIEWS & RANGES
Up
to seven modes are
available in the Stormscope system : Weather,
Main Menu, Checklist
Menu, Checklists (customized as
desired),
Time/Date, Options,
and NAVAID (optional with a
compatibly in-
stalled
LORAN or GPS) .
Two views
available in the weather mode are : 120° forward
view and
360° surrounding
view . The range selected remains the same between
views .
Range displays available on the CRT
are
25,
50,
100,
or 200
run .
When
the Weather mode is initially displayed after power-up,
or when en-
tering
the Weather mode from another mode, the Stormscope
will dis-
play the 200
nm range first .
