GE Aerospace GE9X family
The GE Aerospace GE9X is a high-bypass turbofan family developed for Boeing's twin-engine 777X. Its design combines a large composite fan with advanced core technology to improve fuel efficiency over earlier large GE engines. FAA engine certification was achieved in September 2020 following ground and flight testing. Certification, production and aircraft entry into airline service are separate milestones; the certification announcement alone does not establish commercial service. Exact GE9X model suffixes identify the applicable approved configurations.
