The A330neo is a true new-generation family comprising the A330-900 and its smaller sibling, the A330-800, which will make its first flight in the coming weeks. The A330-900 in particular is the lowest seat-mile cost 300-seater which incorporates highly efficient Rolls-Royce Trent 7000 engines, a new 3D-optimised wing and new sharklets with use of lighter composite materials. Together, these advances bring a significant reduction in fuel consumption of 25 per cent compared with older generation aircraft of similar size.
