Rolls-Royce has completed capability testing on the use of 100 percent sustainable aviation fuel (SAF) on all of its in-production engine lines, the engine maker said Monday during the Dubai Airshow. The final test involved the BR710 business jet engine at its facility in Canada, following the completion of trials on the BR725 and the entire in-production Trent and Pearl lines.

The demonstrations, which involved a range of ground and flight tests to replicate in-service conditions, confirmed that the use of 100 percent SAF does not affect engine performance.
