RADIAL SPREAD
In the strike display mode, it is common for a triangular- shaped
stream of discharge points to appear between the aircraft symbol
and a cluster of discharge points within the range of the WX-500. A
similar stream of discharge points may appear radiating away from
the aircraft symbol in the direction of possible thunderstorm activity
beyond the range of the WX-500. These phenomena are examples
of radial spread. Discharge points in radial spread do not necessarily
indicate the exact location of atmospheric electrical discharges.
To counter- act radial spread, L3 Aviation Products applied its
extensive research in lightning detection to develop enhanced
lightning positioning algorithms. These algorithms (used only in the
cell display mode) greatly reduce radial spread and improve the
depiction of thunderstorms on the display.
