Air New Zealand's biofuel demonstration flight is underway with 6.4t of a 50-50 mix of Jet A and biofuel derived from jatropha plants.

During the two-hour demonstration in Auckalnd, the biofuel blend is powering one of four Rolls-Royce RB211 engines on a Boeing 747-400s aircraft, which is operating under an experimental category flight.

ANZ says the crew "will undertake a number of fuel tests confirming and measuring the performance of the engine and fuel systems at various altitudes and under a variety of operating conditions".

Honeywell subsidiary UOP refined the biofuel, with Terasol Energy sourcing the jatropha plant largely from Tanzania and central India.
