The aircraft will then embark on a short flight test program to certify the changes over the standard A350-900 that will bring the additional range capability. These include a modified fuel system that increases fuel carrying capacity by 24,000 liters, without the need for additional fuel tanks. The test phase will also measure enhanced performance derived from aerodynamic improvements, including extended winglets.
With a maximum take-off weight (MTOW) of 280 tons, the A350 XWB Ultra Long Range is capable of flying up to 9,700 nautical miles or over 20 hours non-stop, combining the highest levels of passenger and crew comfort with unbeatable economics for such distances.
To date, Airbus has recorded a total of 854 firm orders for the A350 XWB from 45 customers worldwide. Singapore Airlines has ordered a total of 67 A350-900s, including the seven Ultra Long Range models.
