ABSTRACT
Use of biofuel as a substitute or extender for mineral jet fuel (Jet A1 kerosene) has rapidly moved from a relatively niche research topic to mainstream attention, with Virgin Atlantic in 2007 announcing plans for biofuel tests with one of its 747s and then making a test flight with a 747 in February 2008, using fuel derived from a mixture of Brazilian babassu palm oil and coconut oil, with one of the four engines connected to an independent biofuel tank that could provide 20 per cent of the engine’s power (BBC, 2008).
