The Engine Alliance is a 50/50 joint venture of General Electric and Pratt & Whitney, a unit of United Technologies Corp. The GP7200 is the result of innovations to the combined technologies of its member companies’ most successful wide-body engines: the GE90 and the PW4000. The GP7200 utilizes the lessons learned from more than 25 million flight hours of successful operation with these legacy engines and incorporates new technology to produce the quietest, most fuel-efficient engine for the A380. The GP7200 is certified at 76,500 pounds (340 kN) of thrust and has the capability to produce more than 81,500 pounds (363 kN). Its emissions are well below current and anticipated regulations. The GP7200 engine is the leading engine for the Airbus A380 aircraft with 19 GP7200-powered A380s in service and 109 more on order. Emirates and Air France currently operate GP7200-powered A380 aircraft. Other GP7200 customers include Korean Air, which will begin operating the A380 in June, Air Austral and International Lease Finance Corporation (ILFC).
