The Engine Alliance is defining the scope of an improvement program for its GP7200 turbofan to help Airbus enhance performance of the A380, and put some very long-range routes within reach.

The initiative, which aims to improve fuel burn another 1-2%, is part of a larger Airbus effort to improve efficiency by taking weight out of the mega-transport. Airlines, too, are looking to do their part, with Emirates saying it is scrubbing its cabin to contribute to the goal of reducing overall aircraft empty weight by 4-5 metric tons. Emirates, the largest A380 customer, has just taken delivery of the first of its 58 aircraft. The engine enhancement and weight efforts are aimed at allowing the carrier to use the A380 more widely, with Emirates hoping it can stretch the aircraft range to allow flights to San Francisco with full passenger and freight loads. The goal is to achieve this by around 2011-12.
