General Electric GE9X-105B1A
General Electric GE9X-105B1A is the certified 105,000 lbf-class (466.9 kN) turbofan selected as the sole powerplant for Boeing's 777X family. Boeing's current airport-planning material and GE program evidence establish the exact 777X application and two-engine installation; lifecycle is kept at development because current evidence does not establish airline in-service entry.
