Pratt & Whitney has commenced flight testing on the PW1900G engine designated to power the Embraer E190-E2 and E195-E2 aircraft.

The geared turbofan (GTF) engine completed its first flight affixed to Pratt’s Boeing 747SP flying testbed aircraft. The flight occurred from Pratt’s flight testing center in Mirabel, Quebec.

“The start of engine flight testing is an important milestone for us as we bring the E-Jets second generation from concept to reality,” Embraer Commercial Aviation president and CEO Paulo Cesar Silva said in a statement.

The PW1900 is the fourth engine in Pratt’s GTF family of engines. Pratt has already delivered GTF engines to Bombardier for the CSeries, Airbus for the A320neo and Mitsubishi Aircraft Corp. for the Mitsubishi Regional Jet (MRJ).
