“The ecoDemonstrator programme is among our most iconic flight demonstrators, having tested 250 technologies since it first took flight in 2012,” said Brian Moran, Boeing’s chief sustainability officer.

“This year’s testing of various cabin interiors aims to help solve for the portion of our airplanes that is not reusable or recyclable while also reducing fuel use and crew workload.”

Eleven aircraft have served as flying test beds for the ecoDemonstrator project since it began in 2012, almost all flying on sustainable aviation fuel (SAF). This year, the 777-200ER will fly on a 30/70 blend of SAF and conventional jet fuel.

“The Boeing ecoDemonstrator programme helps us make tangible improvements to our products – allowing us to reduce the environmental impact of flying, improve the in-flight experience and strengthen the safety of our airplanes,” added Stephanie Pope, president and CEO of Boeing Commercial Airplanes.

“We’re grateful for the many partnerships within aviation and beyond who help us turn the seemingly impossible into reality.”
