STRMSCP softkey (pressing the STRMSCP
softkey again removes Stormscope Lightning
Data from the Navigation Map Page).
In normal operation, the mode and rate are displayed
in the top right corner of the Navigation Map Page. The
mode is described by the word 'STRIKE' when in strike
mode, or 'CELL' when in cell mode.
NOTE: "Cell mode" uses a clustering "pro-
gram" to identify clusters of electrical activ-
ity that indicate cells. Cell mode is most
useful during periods of heavy storm activity.
Displaying cell data during these periods frees
the pilot from sifting through a screen full of
discharge points and helps to better determine
where the storm cells are located.
Stormscope Lightning Data Display Range
Stormscope lightning data can be displayed up
to 2000 nm zoom range (north up) on the Naviga-
tion Map Page. In the 'track up' mode there is a
portion of Stormscope lightning data that could
be behind the aircraft which 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.
To change the display range on the Navigation Map
Page, turn the joystick clockwise to zoom out or turn the
joystick counter-clockwise to zoom in.

NOTE: At a map range of less than 25 nm,
Stormscope lightning data is not displayed but
can still be present. The presence of Stormscope
lightning data is indicated by the annunciation
in the upper right hand corner 'LTNG < 25 nm'
(Figure 8-2).
