Product Overview
Family of turboprop engines is the leading regional airline powerplant in operating economics,
reliability and durability, regularly achieving on-wing times of over 12,000 hours, an exceptional
achievement considering its operation on flights normally less than one hour. Imagine….in the
entire world three out of every four modern regional turboprops are powered by the PW100.
And given today's pressures in fuel pricing, steadily increasing landing fees for noise and
emissions as well as the profit challenges facing the airlines, Pratt & Whitney Canada continues
to invest in the product line to sustain its distinct edge over the regional jets in the short haul
market, far into the future.
In its fifteen years of evolution the PW100 has grown from 2000 shaft horsepower to more than
5000 shaft horsepower, while incorporating the latest advanced technologies from other Pratt &
Whitney engines such as the PW4000 powering the large commercial airliners. Such a strategy
has enabled a tremendous growth in power, continuous improvement in fuel efficiency at only a
modest increase in engine maintenance cost-while also providing the turboprop aircraft with jetlike speed and the associated airline productivity gains.
The PW118, PW120, PW124, PW127 and PW150 Series make up the family with over 4,800
engines delivered to date. A common core configuration has enabled us to bring the benefits of
commonality to the airlines' complete family of 30 through 70 passenger aircraft. Similarly,
flexibility has also proven a strong virtue with the PW100 family's wide range of applications
extending from its dominance in the airline market to utility, fire-fighting, business aviation and
government operations.
