Airbus’ A340-600 also is an ultra-long-haul leader, with a range of 7,900 nautical miles. The jetliner’s four Rolls-Royce Trent 500 engines use only 56,000 lbs. of their certified 60,000 lbs. of thrust, resulting in longer on-wing lives. In addition, the use of four engines – as opposed to two larger power plants – allows for a 13 per cent reduction in maintenance costs for operators.In addition, the A340-600 offers unmatched operational flexibility on non-stop flights over remote areas such as oceans and mountain ranges, allowing for operations that are not subject to ETOPS (Extended-range Twin-engine Operational Performance Standards) regulations. This enables airlines to fly more direct routes – even long distances over water or on segments far from airports – saving travel time and cutting fuel consumption.
