Airbus continues to explore the impact of SAF use on helicopter systems, and has performed the first ever all-SAF flight. The goal is to halve carbon emissions by 2030.

As part of a campaign to certify the use of unblended SAF in helicopters, Airbus tested the performance of an H225 by burning the clean fuel in one of its two engines. The goal is to exceed the current 50 per cent SAF limit.

In a world first, Safran has run a helicopter engine on 100% sustainable aviation fuel. A test will be carried out to determine the operational impact on using only SAF on a helicopter engine.
