Airbus says it has completed a first test flight of its A350-1000ULR widebody aircraft, designed for ultra-long-range operations of up to 22 hours non-stop. The company reports that the plane, equipped with special flight-test instrumentation, flew for 3 hours and 43 minutes and reached an altitude of just over 41,000 feet (12,500 metres). Airbus describes the aircraft as part of the A350 family’s ultra-long-range “ULR” variant, which includes modifications needed for significantly extended range. Among the changes is an additional fuel tank intended to support flights of about 18,500 kilometres (11,500 miles). Airbus says the test flight from its Toulouse facility in southern France starts a broader two-month certification test programme for the modified configuration. The A350-1000ULR is ordered by Australian airline Qantas, with Airbus noting the aircraft will enable non-stop services between Sydney and London. Airbus currently plans to deliver the first A350-1000ULR to Qantas in April 2027, after Qantas previously targeted a 2025 start date. Sources also note that the longest current commercial flight is Singapore Airlines’ service from Singapore to New York, which covers 15,350 kilometres in over 18 hours.
