Boeing’s confirmation in March that GE Aviation will provide the new GE9X engine to power its proposed 777X development marked the culmination of three years of preliminary work between the engine maker and the airframer in their quest to be in a position to promise a 10 percent reduction in fuel burn compared with the GE90-115B engines on the existing 777-300ER. Also promised is a 5 percent improvement in specific fuel consumption over rival widebody engines by 2020.
