The A350-900ULR has a max fuel capacity of 34,500 US gallons
The Airbus A350 is a long-range, wide-body twin-engine airliner. The A350-900ULR is a special variant of the Airbus A350-900, designed for non-stop flights on ultra-long stretches, lasting up to 18 or 19 hours. The A350-900ULR has a maximum fuel capacity of 34,500 US gallons (approx. 130.7 tonnes or 288,000 pounds of fuel). This is achieved without installing supplementary fuel tanks; instead, a modified fuel system utilises the additional space in the centre wing box.
The A350-900ULR increases the baseline Airbus A350-900's maximum non-stop range by about 1,400 nautical miles (2,593 kilometres). This allows the jet to connect city pairs over 17,000 kilometres (9,182 nautical miles) apart, such as the route from Singapore to New York. The A350-900ULR is used on the longest flight in the world, Singapore Airlines Flights 23 and 24 from Singapore to New York JFK.
The A350-900ULR was designed to address the rising demand for greater flight durations without compromising the passenger experience. The A350 is made from advanced materials, with 70% of the aircraft being composite and titanium, resulting in lower weight and reduced maintenance. This, combined with its fuel-efficient Rolls-Royce Trent XWB engines, allows the A350-900ULR to offer an unparalleled range without sacrificing comfort.
The A350-900ULR has a maximum takeoff weight (MTOW) of 280 tonnes (620,000 pounds) and is the smallest variant of the A350 family, coming in three different weight variants: regional, classic, and ULR. The A350-900ULR's fuel capacity increase from the baseline A350-900 has resulted in a significant extension of its maximum range, allowing it to compete with other long-haul aircraft in the market.

The A350-900ULR's modified fuel system utilises the additional space in the centre wing box
The Airbus A350-900ULR is a special variant of the Airbus A350-900, designed to deliver comfortable and fuel-efficient rides for travellers over long distances. It has a maximum non-stop range of about 9,700 nautical miles (18,000 km), enabling it to serve ultra-long-haul routes of up to 18 to 19 hours.
The A350-900ULR's ability to fly these extended routes is made possible by its modified fuel system, which utilises the additional space in the centre wing box. This innovative design modification allows the aircraft to carry more fuel without the need for supplementary fuel tanks or significant structural changes. By optimising the space within the existing fuel tanks, the A350-900ULR achieves a maximum fuel capacity of approximately 34,500 US gallons (130.7 tonnes or 288,000 pounds of fuel). This increased fuel capacity directly contributes to the aircraft's extended range and ability to perform non-stop flights on ultra-long stretches.
The absence of additional structural modifications means that the A350-900ULR retains the same type certificate and model name as the standard A350-900. This design approach not only simplifies the certification process but also maintains the aircraft's aerodynamic efficiency. Furthermore, the A350-900ULR incorporates larger winglets, increased wing twist, and a greater maximum takeoff weight, all contributing to its improved performance and range.
The A350-900ULR's modified fuel system, by utilising the centre wing box space, showcases Airbus's commitment to optimising fuel efficiency. This design philosophy is evident in the A350 platform's use of Rolls-Royce Trent XWB engines, which consume approximately 25% less fuel than their predecessors. The combination of a modified fuel system and efficient engines enables the A350-900ULR to address the challenges of rising fuel prices and the demand for longer-duration flights without compromising passenger experience.
In conclusion, the A350-900ULR's modified fuel system, utilising the additional space in the centre wing box, is a key enabler for its impressive ultra-long-haul capabilities. This innovative design approach, coupled with efficient engines, positions the A350-900ULR as a competitive option for airlines seeking to operate non-stop flights on extended routes, catering to the needs of travellers who prefer journeys without stopovers.

The A350-900ULR's Rolls-Royce Trent XWB engines consume 25% less fuel than predecessors
The Airbus A350-900ULR is a special variant of the Airbus A350-900, which is the smallest variant of the A350 family. The A350-900ULR has been designed to serve non-stop flights on ultra-long stretches, lasting up to 18 or 19 hours, and covering distances of over 17,000 kilometres (9,182 nautical miles) without a stopover.
The A350-900ULR is powered by the Rolls-Royce Trent XWB engine, which is also used in the A350-900, although the engine variant differs. The Rolls-Royce Trent XWB engine consumes 25% less fuel than its predecessors, contributing to the aircraft's ability to fly ultra-long-haul routes.
The A350-900ULR has a maximum fuel capacity of approximately 34,500 US gallons (130.7 tonnes or 288,000 pounds of fuel). However, it achieves its impressive range not through additional fuel tanks, but through a modified fuel system that utilises the additional space in the centre wing box. This allows for greater fuel capacity without the need for supplementary fuel tanks.
The Rolls-Royce Trent XWB engine has been a reliable powerplant for the Airbus A350 family. By February 2018, the engine had accumulated 1.3 million flight hours with a 99.9% dispatch reliability. The higher-thrust variant of the engine, the XWB-97, has been less profitable, as extending time-on-wing is more advantageous for airlines. Nevertheless, the Trent XWB engine has played a crucial role in the success of the Airbus A350, including the ultra-long-range A350-900ULR variant.
