The competing Rolls-Royce Trent 900 was named as the lead engine for the then-named A3XX in 1996 and was initially selected by almost all A380 customers. However the GE/PW engine increased its share of the A380 engine market to the point where as of September 2007 it will power 47% of the super-jumbo fleet. This disparity in sales was resolved in a single transaction, with Emirates' order of 55 GP7000-powered A380-800s, comprising over one quarter of A380 sales (as of September 2007). Emirates has traditionally been a Rolls-Royce customer. A380 aircraft powered by the GP7000s will have A380-86X model numbers as 6 is the code for Engine Alliance engines.
Ground testing of the engine began in April 2004 and the engine was run for the first time on an A380 on August 14, 2006. The American Federal Aviation Administration certified the engine for commercial operation on January 4, 2006. On August 25, 2006, an A380-861 test aircraft (MSN 009) made the first flight of an Engine Alliance powered A380. The flight began and ended at Toulouse and lasted about four hours. Tests were performed on the engines flight envelope, cruise speed, and handling. A day earlier, the same aircraft performed rejected takeoff tests on the engines
Airbus' casting commotion: as the largest commercial airplane ever built, the Airbus A380 is expected to take passengers longer distances with better fuel economies. Key ingredients in this aircraft's success are engineered cast components.
