1.4 LIGHTNING DISPLAY OVERLAY
The EHSI displays weather avoidance information from a Goodrich WX-
500 Stormscope®. The lightning overlay will present electrical discharges
as an overlay to the normal EHSI functions. This overlay is only available
when the EHSI is in either 360 Map or Arc Map modes. Figures 1-11 to 1-
13 are on a foldout page for reference as the section is being reviewed.
1.4.1 DISPLAY SYMBOLS
A white symbolic lightning bolt indicates strike or cell locations. These
lightning bolts are maintained on the display for a period of up to 3 min-
utes. The smallest size is used for display ranges of greater than 20 NM,
the medium size for ranges of 16 and 20 NM, and the large size for the 10
NM range.
1.4.2 LIGHTNING ANNUNCIATION
A white annunciation located on the lower left corner of the display indi-
cates if the lightning overlay is operating in Cell (CELL), Strike (STRK)
mode, or not selected (Blank). The annunciation in white of XXX, where
XXX is a number representing the approximate number of strikes per
minute, is located directly below the lightning mode annunciation.
Lightning is only displayed when the maximum range is 10 NM or greater.
If the selected range is less than 10 NM, a lightning notification message
“No Lightning Display” will be present for 5 seconds, the EHSI is otherwise
configured to display lightning.
