Ultra-Long-Range Test Flight

An Airbus A350-1000ULR completed a 19-hour, 13-minute test flight from Toulouse, France, to Melbourne, Australia, on July 23,24, simulating the conditions for Qantas’ ‘Project Sunrise’ initiative. The flight. Operated by four Airbus test pilots and five engineers, covered 9,120 nautical miles (nearly 17,000 kilometers) to demonstrate the aircraft’s capability to operate the world’s longest non-stop commercial route from Sydney to London, set to launch in October 2027.

The aircraft was equipped with a 20,000-liter integrated aft fuel tank, allowing it to operate for up to 22 hours and over 10,000 miles. According to FlightGlobal. The return leg from Melbourne to Toulouse, which began on July 27, is expected to last around 24 hours as it takes a longer transpacific route. The flight was among the most tracked on Flightradar24, with as many as 8,000 people following its progress in real time.

Technical Challenges and Simulations

During the test flight. The aircraft’s systems. Including fuel management, climate control, and cabin pressurization—were evaluated under simulated passenger conditions, though According to 20 Minuten, water-filled hoses were used to mimic the weight and body heat of passengers. The test aimed to confirm the aircraft’s ability to support long-haul operations with full passenger loads.

Laura Frommberg, a flight expert cited by 20 Minuten, noted that the test represented a “high hurdle” for the aviation industry, as no commercial aircraft has previously operated a 19-hour non-stop flight. The A350-1000ULR’s design extends its range to approximately 19,000 kilometers, making it suitable for the 22- to 23-hour Sydney to London route.

Project Sunrise and Future Plans

Qantas aims to launch direct flights between Sydney and London under Project Sunrise in October 2027, and later extend the initiative to include direct flights from Sydney and Melbourne to New York. According to Frankfurtflyer.de, the airline plans to use favorable wind conditions over the transpacific route to improve travel times, though the primary Sydney-London route will likely exceed 20 hours.

Richard Quest of CNN recently toured the modified A350-1000ULR, highlighting its specialized features for ultra-long-range operations. The aircraft will need to accommodate not only passengers but also the logistical demands placed on crews during such extended flights. Airbus will continue to conduct certification flights to ensure the aircraft meets safety and performance standards for commercial use.
