Atlas Air Worldwide has completed a transoceanic sustainable aviation fuel (SAF) test flight using a 747-400F.

The flight departed Zaragoza Airport in Spain on 21 December and arrived in Mexico City. It was powered by a blend of fuel containing 2.33 per cent SAF sourced from fresh vegetable oil.

Atlas Air believes it to be the first transoceanic commercial cargo flight in Spain to include a blend of SAF and Jet A-1 fuel.

“Innovative sustainable aviation fuel test projects demonstrate our ability to partner with our customers and suppliers to help create a more sustainable future for the air cargo industry and global commerce,” said Atlas Air Worldwide president and chief executive officer John Dietrich.

“Through ongoing meaningful partnerships, we will drive wider acceptance and availability of SAF, which will lower costs and have a positive impact on our industry and the environment.”

Atlas Air partnered with CLH Group subsidiary Exolum, utilising its Avikor platform to implement the trial. Given the adaptable nature of SAF, no additional adjustments to fuel or engine components were necessary, Atlas Air said.

The final blend was certified according to DEF STAND 91/091, with the SAF component certified for sustainability in accordance with International Sustainability & Carbon Certification (ISCC) guidelines.

Exolum CEO Andrés Suarez said: “One of the main targets of Avikor is to promote universally a more sustainable way to fly, offering both individuals and enterprises the possibility of using sustainable aircraft fuel which reduces fuel emissions during flights and helps to improve our planet responsibly, without sacrificing the convenience of flying.”
