Pratt & Whitney Canada PW810 Engine Development Program Enters High Gear

GENEVA, SWITZERLAND, May 20 (MARKET WIRE) --
Pratt & Whitney Canada (P&WC) has started detailed design work as well
as advanced production preparations for the all-new PW810 engine, just
three months after the official launch of its 10,000-pound-thrust-class
PW800 engine family. Pratt & Whitney Canada is a United Technologies
(NYSE: UTX) company.

Preliminary design for the PW810, selected by Cessna Aircraft to power
its new large-cabin Citation Columbus business aircraft, has been
completed. P&WC engineers are now entering into the detail design of
various components with collaboration from suppliers and other partners.
The company has also started production readiness planning to ensure the
engine can be assembled and tested to best meet customer demand.

"We are simulating and validating various production processes, just like
we did to achieve a step change in the production of our PW600 low-thrust
engine family," said Dan Breitman, vice president, PW800 Programs. "We
are working with the objective of significantly reducing assembly and
test time for the PW800 as it relates to our current standards."

This next-generation product raises the bar on performance and economics
by taking advantage of the latest materials, aerodynamic and design
technologies developed by the company. It incorporates advanced fan,
compressor, turbine and low-emissions TALON(TM) combustion systems for
exceptional fuel consumption, future thrust-growth capability and
improved environmental friendliness.

In addition, the PW810 will surpass International Civil Aviation
Organization (ICAO) emissions standards by up to 50 per cent for nitrous
oxide and by up to 35 per cent for carbon monoxide emissions, and will
also achieve low unburned hydrocarbons and smoke emissions. Moreover, it
is designed for low noise, well below Stage IV standards.

First run of the PW810 is being targeted for mid-2009. The Citation
Columbus, designed for intercontinental travel with a target range of
4,000 nautical miles (7,408 kilometres) at Mach 0.80 carrying eight
passengers, is expected to enter customer service in 2014.

Pratt & Whitney Canada, based in Longueuil, Quebec, is a world leader in
the design, manufacture and service of aircraft engines powering
business, general aviation and regional aircraft and helicopters. The
company also manufactures auxiliary power units and industrial gas
turbines. United Technologies, based in Hartford, Conn., USA, is a
