I think indeed the ULR will have its own campaign of test flights. I would not expect a whole campaign, it's not a new type or even a new sub-type, just a variant. I would say some specific additional tests may be needed. |

Disappointing that Flight Global doesn’t know the difference between MTOW and aircraft weight, calling the ULR a heavier version !

Is this frame going to undergo a separate flight test campaign and certification? Hanging the engines before paint is not the usual sequence is it? Airbus is answering the question in detail. From the press release already posted by Kronus : www.airbus.com/newsroom/press-releases/en/2018/04/ultra-long-range-a350-xwb-completes-first-flight-.html"The aircraft powered by Rolls-Royce Trent XWB engines has embarked on a short flight test programme to certify the changes over the standard A350-900 that will extend its range capability to 9,700 nautical miles. These changes include a modified fuel system that increases fuel carrying capacity by 24,000 litres, without the need for additional fuel tanks. The test phase will also measure enhanced performance from aerodynamic improvements, including extended winglets". To summarise, Airbus needs to certify the A359 ULR new fuel delivery software and 'plumbing' as well as the new wing twist and winglets. |
