Airbus A400M completes helicopter air-to-air refueling Certification

Getafe, 19 April 2021 – The Airbus A400M new generation airlifter has completed the majority of its development and certification objectives by successfully conducting a large helicopter air-to-air refueling certification campaign. With the completion of all mandatory night operation trials later this year, Airbus Defense and Space hopes to obtain full helicopter air-to-air refueling certification.

The flight tests, performed in coordination with the French Armament General Directorate (DGA), involved operations with two French Air Force H225M helicopters.

The campaign took place in day and night conditions over the west coast of France at between 1,000 ft and 10,000 ft and flight speeds as low as 105 knots. During those flights, a total of 81 wet contacts and transfers of 6.5 tonnes of fuel were achieved, which included simultaneous refueling of two helicopters for the first time. The tests confirmed the positive results of the dry and wet contact operations conducted in 2019 and 2020.

Helicopter air-to-air refueling is a unique military capability and key for Special Forces operations, involving aircraft with different flight profiles and sharing a very limited common flight envelope, requiring close formation flying patterns at low altitudes and night time conditions.

With this capability the A400M becomes one of the few tanker aircraft in the world capable of such operations. The multi-purpose H225M is one of the few helicopters in the world capable of in-flight refueling, extending the standard 700 NM range by up to 10 hours flight time.

A400M as tanker

The A400M is certified as standard to be quickly configured as a tanker. Carrying up to 50.8 tonnes of fuel in its wings and centre wing box, without compromising any cargo hold area, two additional cargo hold tanks can also be installed, providing an additional 5.7 tonnes of fuel each. The separate cargo-hold tanks allows for the use of different types of fuel, enabling the A400M to cater for the needs of different types of receiver aircraft.

As a tanker, the A400M has already demonstrated its ability to refuel fighter receivers such as Eurofighter, Rafale, Tornado or F/A-18 at their preferred speeds and altitudes, and is also able to refuel other large aircraft such as another A400M for buddy refuelling, C295 or C-130

Airbus Enhances A350 Cabin with 10-Abreast Seating

Airbus has announced a new partnership with Jiatai Aircraft Equipment, a Chinese aircraft seating manufacturer, to supply upgraded economy-class seats for the A350 widebody series.

This collaboration, unveiled at the 2024 Airshow China, focuses on developing a newly designed economy seat tailored for the A350‘s New Production Standard (NPS) cabin.

One of the key features of the NPS cabin is the ability to accommodate 17-inch wide economy seats, compared to the previous 16.5-inch wide seats that airlines were limited to in the A350’s earlier configurations.

This change is made possible by the expanded space in the NPS cabin, which is 35 inches longer and 4 inches wider than the previous version. This extra space is achieved by slightly moving the cockpit wall forward and shifting the rear pressure bulkhead back by one frame.

The wider cabin allows airlines to add up to 30 extra economy seats without compromising comfort. For airlines opting for a 3-4-3 seating layout, the 17-inch wide seats are an excellent choice for a more comfortable passenger experience. However, some airlines, such as Iberia, may choose to retain a 9-abreast layout with wider seats for added comfort.

The NPS cabin also offers enhanced flexibility for airline operators. One major advantage is the ability to easily switch between a 9-abreast and 10-abreast seating configuration without requiring significant downtime for aircraft reconfiguration. Airlines can use the same seat rails, tracks, and IFE interfaces, making the transition smoother and quicker.

In addition, the design of the floor attachments and air-conditioning systems has been optimized for 10-abreast seating, meaning airlines can upgrade their cabins without needing to make substantial modifications to the aircraft’s structure.

Though it’s still unclear when Jiatai’s economy-class seats will be officially added to the A350’s Buyer Furnished Equipment (BFE) catalogue, the collaboration marks a significant step toward enhancing the A350’s cabin offerings.

With this partnership, Airbus is providing more seating options for airlines, ensuring that they can meet diverse customer needs while improving overall operational efficiency.
