Jeppesen Adds Worldwide Lightning Maps

Dec. 5, 2007, Englewood, COLO – Jeppesen recently enhanced its full
lineup of weather products by superimposing worldwide lightning data
over its infrared and visible satellite imagery maps.

The World Wide Lightning Location Network (WWLLN) is an innovative
technology developed jointly at the University of Washington (Seattle)
and University of Otago (Dunedin, New Zealand) that allows for the
detection of cloud-to-ground lightning using a network of 20-30 sensors
around the globe. The sensors can detect lightning strikes up to 10,000
km away by measuring Very Low Frequency (VLF) radiation that emanates
from the strikes. The lightning strike location accuracy is a few
kilometers, and the detection efficiency is sufficient to detect a very
high percentage of thunderstorms in real-time.

This additional data allows pilots to determine where convection and
thunderstorms are located in worldwide areas, even where radar data is
not normally available. This is especially useful over oceanic regions
where only satellite imagery exists to depict clouds. Now pilots will
know which systems are producing lightning, and make decisions based on
real-time, accurate data.

Worldwide satellite maps are usually updated every one to three hours,
and contain the latest 30 minutes worth of lightning strikes.

“Jeppesen is at the forefront of state-of-the-art aviation weather
products and the first aviation weather company to make this lightning
data available. The benefits for pilots are wide ranging, especially
when radar information is not available,” said Mike Cetinich, product
manager.  “We are committed and solely focused on aviation weather
products that add value for our customers, and help them make more
informed decisions.”

 For more than 70 years Jeppesen has made it possible for pilots and
their passengers to safely and efficiently reach their destinations. 
Today this pioneering spirit continues as Jeppesen delivers essential
information and optimization solutions to improve the efficiency of
air, sea and rail operations around the globe.  Jeppesen is a
subsidiary of Boeing Commercial Aviation Services, a unit of Boeing
Commercial Airplanes.
