GE9X On Course Flight Testing In 2017
Ground testing has started of the first 100,000-pound-thrust GE9X turbofan, which is the largest-ever commercial aircraft engine.

It is now three months since GE Aviation started ground testing the first full GE9X development engine at its Peebles, Ohio facility. That was on March 25 and, according to the manufacturer, this First Full Engine to Test (FETT) stage has been achieved much earlier than usual for a complex powerplant development—just six months after the design was finalized—and this stands the GE9X in good stead to complete certification as planned in 2018.
