NAVIGATION MAP PAGE
Displaying Lightning Data on the Navigation
Map Page
Pressing the LTNG softkey after pressing the MAP
softkey displays WX-500 Stormscope data on the Naviga-
tion Map Page within a maximum of 200 nm radius of the
aircraft.
The Navigation Map Page displays cell or strike
information using yellow lightning strike symbology.
This added capability improves situational awareness,
which makes it much easier for the pilot to relate storm
activity to airports, navaids, obstacles and other ground
references.
To display lightning data on the Navigation
Map Page:
1. Press the
MAP
softkey.
2. Press the
LTNG
softkey. Press the
LTNG
softkey again to remove lightning data from
the Navigation Map Page
In normal operation, the current 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.
The strike data display phases are:
1. Lightning Symbol (latest strikes; less than one
minute; a black guard band is placed around
the strike symbol during the first six seconds of
display)
2. Large Plus ‘+’ sign (more than one minute old)
3. Small Plus ‘+’ sign (more than two minutes old)
4. Strike Data is no longer displayed (after three
minutes)
Lightning Data Display Range
Lightning data can be displayed up to 800 nm
zoom range, but the data only goes out as far as the
Stormscope can report (200 nm). The 500 nm zoom
range will display all lightning data. Ranges greater
than 500 nm do not display any further Stormscope
data.
