AAI Unmanned Aircraft Systems Aircrew Supports Meteorological Research Amid
Brutal Winds and Temperatures

WASHINGTON, Oct. 22, 2012 (GLOBE NEWSWIRE) -- AUSA Annual Meeting & Exhibition
— AAI Unmanned Aircraft Systems, an operating unit of Textron Systems, a
Textron Inc. (NYSE:TXT) company, announced today that its Aerosonde® Small
Unmanned Aircraft System logged 168 flight hours in the frigid, harsh climate
of Antarctica, supporting meteorological research by the University of
Colorado's Cooperative Institute for Research in Environmental Sciences and
Department of Atmospheric and Oceanic Sciences. Each Aerosonde aircraft was
outfitted with meteorological instruments to measure pressure, temperature,
relative humidity, winds, net radiation, surface temperature and ice

The University of Colorado team, led by Dr. John Cassano, is studying
Antarctic polynyas, or areas of open water surrounded by sea ice. To learn
more about this phenomenon, the crew directed the Aerosonde aircraft through
low-level flights around 300 feet above the water's surface to measure wind
speed, temperature and moisture in an area called Terra Nova Bay. Flights also
included spiral ascents and descents to capture the atmosphere at various
heights over the polynyas. Launching from an ice runway, the Aerosonde
aircraft conducted beyond-line-of-site operations of up to 18 hours in
temperatures as low as minus 37 degrees Celsius and winds up to 81 miles per

"The crew and aircraft have really proven themselves in one of the harshest,
least-forgiving environments possible for unmanned aircraft system
operations," said Dr. Cassano.

This was the second successful deployment AAI Unmanned Aircraft Systems has
conducted with the University of Colorado team. In 2009, a six-week
exploration of the katabatic winds present on the coast of Antarctica allowed
researchers to generate highly detailed, three-dimensional maps to help study
their relationship to sea ice formation.

"Once again, Antarctica has proven to be an extremely challenging environment;
however, this small group of dedicated professionals has demonstrated what is
possible at the extreme edge," said Nick Logan, flight operations manager for
AAI Unmanned Aircraft Systems' Australia-based strategic business Aerosonde
Pty Ltd, which led the 2012 and 2009 Aerosonde SUAS deployments.
