EAST HARTFORD, Conn., March 14, 2013 /PRNewswire/ --Pratt & Whitney
AeroPower's* APS2600[E] auxiliary power unit (APU) has been selected by
Embraer for its second generation E-Jet. Pratt & Whitney is a United
Technologies Corp. (NYSE: UTX) company.

"We are delighted to continue our long-standing relationship with Embraer and
provide our APS2600[E] APU for the second generation E-Jet," said Eileen P.
Drake, vice president and general manager, Pratt & Whitney AeroPower. "The
APS2600[E] APU provides exceptional value to customers by providing increased
electric power capability, both on the ground and in flight, a significantly
higher operating altitude, and world-class reliability."

In addition to the APS2600[E] APU, Pratt & Whitney AeroPower APUs can be found
on Embraer's ERJ-145, E170/175 and E190/195 fleets. Pratt & Whitney AeroPower
was also recently selected for Embraer's KC-390 military cargo tanker for the
Brazilian Air Force.

APUs provide aircraft with secondary power in the form of high pressure air
for main engine starting, cabin air conditioning and electric power while on
the ground. APUs can also provide backup electric power during in-flight

The second generation Embraer E-Jets will also be equipped with Pratt &
Whitney's PurePower® PW1700G and PW1900G engines, which will offer significant
reductions in fuel burn, emissions, noise and operating costs compared to
today's aircraft.
