The Royal Netherlands Air Force (RNLAF) has successfully flight tested a Boeing AH-64D Apache aircraft using a blend of sustainable bio-kerosene and standard aviation jet fuel.

The test is a part of a biofuel flight test programme authorised by Netherlands Ministry of Defence, which includes seven flights to determine the technical feasibility of flying rotorcraft using renewable fuels.

The biofuel, a biosynthetic paraffinic kerosene (bio-SPK) was produced by using algae-based biomass and used cooking oil.

The RNLAF carried out the 20-minute test flight at its Gilze-Rijen Airbase in collaboration with other programme team members including Boeing, Honeywell and GE Aviation.

In a series of preflight tests, the 50/50 bio-kerosene and traditional jet fuel blend met or exceeded the JP-8 fuel specifications for the Apache.
