11.2.4 Changing the Stormscope Data Mode
Cell display mode uses a clustering program to locate storm cells instead of
individual discharge points. This mode is most useful during periods of heavy
storm activity. Strike display mode is used during periods of light electrical
activity. It is useful in plotting initial lightning discharges associated with a
building thunderstorm.
1. While viewing the Weather Stormscope page, touch
MENU
.
2. Touch the
Cell
or
Strike
key to select the display mode.
11.2.5 Changing the Stormscope Data Display Range
Stormscope data can be displayed on the Map page 2,000 NM zoom scale,
but the data only goes out as far as the Stormscope can report (200 NM). The
500 NM zoom scale will display all lightning data. Scales greater than 500 NM
do not display any additional Stormscope data.
1. While viewing the Stormscope page, touch the
In
and
Out
keys to display a larger or smaller area.
11.2.6 Displaying Stormscope Data on the Map Page
The Map page displays cell or strike information using yellow lightning strike
symbology overlaid on a moving map. This added capability improves situational
awareness, which in turn makes it much easier for the pilot to relate storm activity
to airports, NAVAIDs, obstacles and other ground references. Refer to section
8.1.1.6 for details about viewing Stormscope data on the Map.
NOTE:
The selected lightning display type, cell or strike, will be shown the
same on both the Stormscope and the Map pages.
