Airbus A350-1000ULR MSN707 completed its maiden flight on 2 June 2026 in Toulouse, initiating a two-month EASA certification campaign for Qantas Project Sunrise. The production airframe integrates a 20,000-litre rear centre tank, extending range by 1,000 nautical miles to enable 22-hour non-stop flights between Sydney and London. Certification focuses on fuel system architecture, Fuel Quantity Management transfer sequencing, and a new 300kg lighter galley cooling system. Cabin ventilation and temperature control are validated using 1,000 sensors and passenger heat dummies to simulate full-load thermal dynamics. MSN707 will serve as a test bed before retrofitting to Qantas specifications, with first delivery scheduled April 2027 and inaugural service October 2027.
