The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 pounds-force (360 to 510 kilonewtons).
In addition to the wide-body engine family, Rolls-Royce was one of the founding partners of International Aero Engines, which in turn developed the IAE V2500 engine. It is currently used on such aircraft as the Airbus A320ceo family (excluding the A318), the McDonnell Douglas MD-90 and the Embraer KC-390.
On multi-engine aircraft, engine positions are numbered from left to right from the point of view of the pilot looking forward, so for example on a four-engine aircraft such as the Boeing 747, engine No. 1 is on the left side, farthest from the fuselage, while engine No. 3 is on the right side nearest to the fuselage.
