Pratt & Whitney has formally begun certification trials for its PW1500G engine, on track for year-end approval to support first flight of the Bombardier CSeries CS100. The engine-maker inaugurated US FAA certification testing in mid-January with icing evaluations at its Manitoba, Canada facility. The PW1500G has accumulated more than 1,350h of testing, including 250h of flight testing under the wing of Pratt's modified Boeing 747SP testbed.

"The [specific fuel consumption] on the airplane looks very, very good," says Chet Fuller, Bombardier senior vice-president, sales, marketing and asset management. "It looks like we're going to produce exactly the right thrust with the right SFC at entry into service."

The CS100 is expected to fly in late 2012 or early 2013, and enter service approximately a year later. To date, nine engines, including the PW1200G series for the Mitsubishi Regional Jet, which enters service in 2014, have completed more than 2,000h of testing.
