How the Trent XWB Broke the Long-Haul Record


An ETOPS rating certifies how long a twin-engine aircraft can safely operate with just one engine, measured in the time it takes to reach the nearest diversionary airport. This limits which aircraft are allowed to fly over deserted areas and oceans, and for how long.                                   

Basically, ETOPS is an imaginary tether tied around the aircraft that regulates where it can fly. Read on to find out how one Rolls-Royce engine, the Trent XWB, broke this record, and went on to be the fastest-selling civil aircraft engine in its class.
