OPTIONAL EQUIPMENT
To display Stormscope Lightning Data on
the Navigation Map Page:
1. Press the MAP softkey.
2. Press the 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 “program”
to identify clusters of electrical activity 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 on the
Navigation Map Page at up to 2000 nm zoom range
(north up).
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 the aircraft (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).

Customized Display

lightning data on the Navigation Map Page using the
Weather Group Options in the Map Setup Menu (Figure
8-3).
