SUPPLEMENT 12
The 3M (Ryan) Stormscope, WX-11 Owners Manual, should be read
thoroughly by the operator before using the displayed data to interpret
\,,,,,,_,I
thunderstorm activities.
(a) Operation (Pre-Flight)
( 1) Turn power/ mode switch to ON.
(2)
Turn WX-11 to FWD, if desired, to concentrate system
memory to forward 180° reception.
(3) Push test button (TST). Check for proper signal reception on
the 45° bearing. Check that signal reception occurs at both 100
NM range and 200 NM scale selections. No signal will normally
be seen on the 50/25 NM scales.
(4)
Push clear button (CLR) to clear dots from screen so new
thunderstorm data can be displayed.
(5)
Turn Range-Selection switch to desired range in nautical miles.
(6)
For night operation, the brightness control (BRT) controls
intensity of dots for comfortable viewing.
(7)
Gyro Status. Depress TST and CLR and hold them down to
ensure gyro inputs are being used for stabilization.
If GYRO ON appears on the Model WX-11 Display, the
dot pattern indicating thunderstorm activity will automatically
turn relative to the aircraft heading as the aircraft turns.
If GYRO OFF appears on the display, the dot pattern
will remain stationary as the aircraft heading changes.
In this case, it will be necessary to clear the display
manually by pushing the CLR button each time the
heading is changed.
Gyro status can be changed from GYRO ON to GYRO
OFF or vice versa by simply holding down both the
TST and CLR buttons for three seconds or more.
NOTE
Operator should be aware that occasional
aircraft electrical system (pitot heat, radio
transmissions, etc.) activations or noisy
external electrical devices in close ground
proximity may cause signal patterns to be
displayed. Such signals should be disregarded
and cleared by the CLR button.
