B777 Engine

Boeing offers the 777 with engines from three manufacturers; General Electric, Pratt & Whitney, and Rolls Royce. The three types of engines are designed to the same specifications and offer nearly identical performance giving each airline the option of using the manufacturer of their choice. Since the 777 launch customer, United Airlines, selected Pratt & Whitney engines, basic certification will be conducted on four airplanes using the PW4084 engines. British Airways bound aircraft will be used for the engine-airframe testing of the General Electric GE90 engines. Certification of the GE configuration was completed on November 9, 1995, with delivery to British Airways on November 11, 1995. The Rolls-Royce Trent 800 engine tests will be conducted on Cathay Pacific Airways aircraft, and certification of the Rolls-Royce equipped 777 is expected in January 1996, with first delivery going to Thai Airways International.
