Airbus aircraft creates history with sustainable fuel flight

RAF Voyager’s test flight is a world first for an in-service military transporter. It is also the first 100 per cent SAF flight of any aircraft type carried out in UK airspace.

An RAF Voyager – the military variant of the Airbus A330 commercial jetliner - took to the skies above RAF Brize Norton in Oxfordshire on Wednesday powered completely by 100 per cent SAF on both engines, paving the way for a range of possibilities for the future of flying military aircraft.

The flight was a joint endeavour between the RAF, aircraft manufacturer Airbus, the UK Ministry of Defence’s Defence Equipment and Support agency, British aircraft leasing company AirTanker and engine manufacturer Rolls-Royce, with the fuel supplied by Air bp.

Michael Schoellhorn, CEO of Airbus Defence and Space, said: “True to our purpose of 'pioneering aerospace', we have gladly supported the Royal Air Force on this landmark sustainable-fuel test flight.

"I commend our UK customer for this achievement which helps pave the way for a sustainable reduction of carbon emissions of our military aircraft fleets. Airbus engineers have made a significant contribution to this RAF mission by providing on-the-ground expertise in recent weeks and securing the necessary MoD military flight permits.”

Airbus has confirmed that the wings of the plane were made at the company's Broughton plant. 

Sustainable Aviation Fuel – which is made from waste-based sustainable feedstocks, in this case used cooking oil – reduces lifecycle carbon emissions by up to 80 per cent compared to the conventional fuel it replaces, lessens the RAF’s reliance on global supply chains and improves operational resilience by reducing the necessity for fuel resupplying.

As different approaches will suit different platforms and environments, a range of alternative fuel options are being looked at to ensure the UK is at the forefront of this developing technology.

The 90-minute return flight from RAF Brize Norton, flown by a combined Airbus, RAF and Rolls-Royce flight-test crew, replicated an air-to-air refuelling sortie and was witnessed by senior RAF and industry representatives. The RAF said it demonstrated the potential for its future operational capability, ensuring the ability to contribute to UK defence wherever and whenever it was required.

Experimental test pilot and captain of the flight, Jesus Ruiz, said: “From the crew perspective, the SAF operation was ‘transparent’, meaning that no differences were observed operationally.

"The Test Plan was exhaustive and robust and has allowed us to compare SAF with JET1 culminating in a flight without a single drop of fossil fuel.

"Teamwork was a key contributor, harmonsing experience from Airbus, Rolls-Royce and the RAF. We feel very proud to be a small part of this huge step for sustainable aviation.”
