澳洲航空首架空中客车 A350-1000ULR(生产序列号 MSN 707)已在法国图卢兹成功完成首飞。此次测试飞行历时 3 小时 43 分钟,标志着为期两个月的认证工作的开始,重点将测试该机型的专用燃油系统(包含一个额外的后中央油箱)以及全新的高效厨房冷却技术。 A350-1000ULR 是专为澳洲航空的“日出计划”(Project Sunrise)而研发的,旨在实现悉尼至纽约和伦敦之间的前所未有的商业直飞航线,航程近 10,000 海里,飞行时间长达 22 小时。这种超远程飞行能力得益于结构上的增强,使飞机的航程增加了 1,000 海里。 完成认证后,MSN 707 将进行改装,以符合澳洲航空的商业规格。澳洲航空已订购了 12 架此类特制飞机,首架交付计划于 2027 年 4 月进行。这一进展是长途航空业的一个重要里程碑,旨在连接全球最后几个尚待开发的直飞航线市场。

最近的一场 Hacker News 讨论探讨了空中客车公司安装后部中央油箱的计划,此举可将其飞机的航程延长约 1000 海里,并实现长达 22 小时的超远程飞行。 社区对此反应不一。许多评论者对直飞前景感到兴奋,认为这可以节省大量时间,并消除转机带来的后勤困扰。然而,也有人提出了技术和经济方面的担忧。怀疑论者指出,增加燃油会增加重量,可能会损害燃油经济性、载货能力和空气动力学性能。一些人还讨论了在没有昂贵高端座椅的情况下,在同一个座位上忍受 22 小时的乘客体验是否真的可行。 这场讨论还涉及了此类飞行的工程挑战,特别是关于厨房冷却系统的部分。专业人士解释了飞机如何在长时间飞行中进行热交换,并指出冷却系统必须针对地面运行和巡航高度进行优化。总而言之,虽然直飞“袋鼠航线”对旅客极具吸引力,但航空业必须在这些消费者利益与大规模、长时间飞行运营所带来的热力学和经济权衡之间取得平衡。

Toulouse, France, 2 June 2026 - The A350-1000ULR (MSN 707), the first of 12 aircraft ordered by Qantas has completed its first flight in Toulouse, France. The aircraft, fitted with special flight test instrumentation, flew for three hours 43 minutes reaching an altitude of slightly above 41,000 feet. The aircraft was flown by a dedicated Airbus Flight Test crew.

The A350-1000ULR is being developed for Qantas Airways to enable non-stop flights between Sydney and New York and London for the first time ever - a distance of almost 10,000 nautical miles, with flight times of up to 22 hours. This is made possible primarily by the integration into the aircraft structure of an additional rear centre tank (RCT), enhancing further the aircraft performance and increasing the range of the aircraft by 1,000 nautical miles.

During the first flight the crew carried out general aircraft performance checks and tested the new fuel system architecture. This marks the start of a two month flight test campaign to certify the modifications. In addition, a new galley air cooling system will also be certified, which features lighter and more efficient refrigeration units for very long flights. The ventilation and temperature control of the cabin will also be thoroughly tested.

Following the flight test campaign, MSN 707 will be retrofitted to Qantas’ commercial specifications.

The second A350-1000ULR to be produced for Qantas and the first scheduled to be delivered to the airline in April 2027, is now at an advanced stage of final assembly and ready to roll out of the paint shop in the coming days. This will be followed by completion of the premium four class cabin layout and engine installation. 

The A350-1000ULR is the fourth passenger variant of the best-selling A350 Family, joining the A350-900, A350-900ULR and the A350-1000. Together, the aircraft have set new standards in long haul air travel, with a step-change reduction in fuel consumption and carbon emissions, and new levels of passenger comfort. 

The passenger line-up will soon be joined by the all-new A350F freighter, also currently under development at Airbus, with first flight planned later this year.

At the end of April 2026, the A350 Family had won 1,579 orders from 68 customers, with over 700 aircraft flying with 41 operators, primarily on long haul services across the globe.

Qantas has ordered 12 A350-1000ULRs under Project Sunrise, designed to overcome one of the last frontiers in non-stop travel from Australia. In addition the carrier also has 12 standard A350-1000s on order for future operation across its long haul network.

Note to editors:

The aircraft was flown by Experimental Test Pilots Thomas Wilhelm and Anthony Flynn, together with Test Flight Engineer Laurent Rossignol. In addition, Lead Flight Test Engineers Tuan Do and Alexia Plumet were onboard, as well as Ground Test Engineer Vincent Frayssinet.
