Lightning data can be displayed up to 800 nm zoom
range (north up). In the ‘track up’ mode there is a
portion of lightning that could be behind the aircraft
that cannot be seen at this range. Since the range of the
Stormscope is 200 nm (in front) in addition to another
200 nm (behind) (400 nm diameter total), the 500 nm
range (in north up mode) shows all the data.
