Rate Counter and Edge Strikes
The BFGoodrich Avionics Systems WX-900 Weather Mapping
System now provides the average number of strikes detected per
minute, regardless of the display range selected. The strike rate
counter, as shown below, is updated every 5 seconds and will
increase/decrease with thunderstorm intensity. This is useful in
determining the relative intensity of all thunderstorms within the
maximum range of the instrument. The counter can display a maxi-
mum of 999 strikes per minute. You can reset the counter to zero at
any time by pressing the CLEAR button.
NOTE
Since the rate counter displays an average number, it is
possible to have strikes showing and the rate counter
displaying 000. In addition, it is possible for the rate counter
to be counting with no strikes showing.
Lightning strikes detected beyond 100 miles will be plotted as a
single pixel on the outer range ring at the corresponding azimuth.
These strikes, as shown above, are called edge strikes. This infor-
mation is provided as an aid for longer range planning. Edge strikes
are included in the rate counter display.
