Part of Embraer’s comfort level is based on the fact the PW1700G will be configured with a 56-in. diameter fan, while the PW1900G will have a 73-in. fan. The smaller engine is a virtual clone of the PW1200G in advanced development for the MRJ, while the PW1900G is the same size as the PW1500G now poised to power the first flight of the CSeries.

First engine test is expected early in 2015 to provide ample margin for the planned first flight of the new Embraer jet in 2016.

Pratt Next Generation Product Family VP Bob Saia says commonality with the MRJ and CSeries engines eases the engine maker’s workload. “These will be newly certificated by model, but a lot of the reports will be based on initial certification tests already conducted on the other engines such as fan blade out and so on.”

Saia adds the selection by Embraer represents “a good fit” for Pratt’s overall market penetration strategy.
