SWITCH BETWEEN DISPLAY MODES
The KMD 550/850 can display the Stormscope
®
data
in one of two modes, either Cell Mode or Strike Mode.
To switch the display between modes press the
MODE button. The currently selected weather dis-
play mode is indicated on the top left of the display
and will toggle between CELL MODE and STRIKE MODE with each
press of the button as shown in Figures 32 and 33. The mode selected
here will remain in effect until you change it, unless the unit is turned off
and back on.
Cell Display Mode
When viewing the dedicated Stormscope
®
display, if cell display mode is
selected, the KMD 550/850 plots a "+" symbol (discharge point) on the
display when it detects associated discharges within the selected range
and view. The KMD 550/850 will plot another "+" close to the first for
each additional discharge determined to be associated with the group.
The KMD 550/850 will not plot a "+" for any discharge not associated
with a group unless it's detected within a 25 nm radius of the aircraft. The
effect of this clustering algorithm is to display the location of storm cells
instead of individual discharges. The cell display mode is most useful
during periods of heavy electrical discharge activity. Using the cell dis-
play mode during these periods frees the pilot from sifting through a dis-
play full of discharge points to determine exactly where the storm cells
are located.
If discharges are detected within 25 nm of the aircraft, the normal
stormscope icon in the Functions Legend will change to one such
as that shown here.
