The Airbus A350F flew for the first time on 29 September, with MSN700 spending 4 hours 10 minutes in the air and reaching 25,000 ft under the control of a five-person Airbus flight-test crew. The sortie starts a certification campaign Airbus expects to run more than nine months and roughly 400 flight hours, with first customer deliveries targeted for the second half of 2026.

"We are now entering into a phase of more or less nine months of certification of flight test until certification. So we are very confident that we are going to deliver the aircraft to the first customers in the second half of next year. I think it's 400 hours of test flight. So we're going to test the aircraft from the bottom to the top because it's a freighter, it's not the same like a passenger aircraft that takes time," Lars Wagner, CEO of Airbus Commercial Aircraft Business, said.

The programme gives Airbus its first credible entry into a large-freighter segment Boeing has dominated for decades. By the end of August the order book stood at 115 aircraft from 14 disclosed customers, which Airbus says represents up to 59 percent of the large-freighter market by orders.

Specifications and the weight case

The A350F carries up to 111 tonnes over a range of up to 8,700 km. Its Trent XWB-97 engines are already established on the A350-1000, and the airframe benefits from the A350's extensive use of advanced materials. Airbus puts the maximum take-off weight advantage at 46 tonnes against competing aircraft and claims fuel-burn and CO₂ reductions of up to 40 percent for comparable payload-range missions — figures that belong, for now, to the category of manufacturer claims pending flight-test validation against the delivery record.

What is certified and flying is the A350 passenger family. The freighter's own performance numbers now face the test fleet: MSN700 will concentrate on aerodynamics, performance and handling, while a second aircraft will address systems and cargo-specific functionality. Planned phases include flutter, handling, anemometry, autopilot and performance testing, plus cargo-system maturity work and hot- and cold-weather campaigns. Airbus has prepared 75 dedicated ULDs representing more than 200 tonnes of test installations. Ground testing has already exceeded 10,000 hours, using around 600 dedicated sensors and roughly 60 km of additional wiring generating as much as 220 GB of data per flight.

"The aircraft is facing reality, and we will see whether the prediction, the measurement we did on the ground are true," Jean-Philippe Cottet, Head of Development Flight Tests at Airbus, said.

A fuselage built around cargo

The design choices are concrete. Airbus shortened the forward fuselage by removing five frames to position the centre of gravity correctly for a fully loaded freighter. It took the front section from the A350-900 and the rear from the -1000, creating what Rémi Maillard, Executive Vice-President Engineering and Head of Technology, calls "a brand new fuselage, 100% fit for cargo operations."

The rear-mounted main-deck cargo door, at 4.3 metres the widest in commercial aviation, is sized so very large aircraft engines can enter and move forward without multiple loading operations. The main-deck floor is reinforced for dense loads, with load distribution managed around the wing box — heavier pallets near the wings, lighter ones at the extremities.

"We have reinforced the main deck to be able to carry heavy loads, dense loads. We talked about running loads, so the key is the density of the pallets that the operators can load. And of course, when you are around the wings, you can have heavier pallets. When you are at the two extremities, you need slightly lighter pallets or less heavy," Julien Puyou, Head of Widebody Programmes, said.

The floor is also watertight with drainage, simplifying cleaning after live animals, food or other loads involving spills. Larger power-drive units and a more robust installation in the loading system are intended to address servicing demands operators know from converted freighters.

Payload flexibility as an economic argument

Airbus frames the aircraft as an economic tool rather than a specification sheet. Crawford Hamilton, Head of Freighter Marketing, said: "Customers want to maximise revenue. They want to get the most lucrative loads on board, and the flexibility to be able to react to get those lucrative loads, and then also make sure that they can boost their service levels by having a reliable airplane. Range flexibility is important because there are lots going on now where there are no-fly zones for various aircraft."

The SmartCargo architecture tracks pallet positions and environmental parameters, letting operators compare actual loading against the intended load plan. Eight temperature-control zones, with sensors recording conditions across multiple zones, support shipments from fresh produce to live animals and create a digital record for sensitive cargo. "We incorporated some systemic equipment, what we call the smart cargo, which is a way to help automated operation, data-based operation for freight operators that would simplify further their operation in terms of knowing their payload and how the loading of the aircraft is performing," said Philippe Mhun, Executive Vice-President Programmes and Services.

A customer base spread across freight models

The disclosed customer base spans combination carriers (Korean Air, Cathay Pacific, Singapore Airlines), all-cargo operators (Silk Way, CMA CGM, MNG) and Atlas Air, the largest customer with 20 aircraft, alongside leasing interests. That mix gives Airbus operational validation across different freight networks from the outset and gives operators A350 family and crew commonality with passenger variants.

An ageing large-freighter fleet, tightening emissions requirements and demand for new capacity form the market backdrop. The nine-month flight-test campaign will now determine whether the weight advantage and 40-percent fuel-burn claims survive contact with measured data — and whether Airbus can convert a 59-percent order share in the segment into sustained delivery performance from the second half of 2026.
