A flight running on biojet fuel has successfully completed its test journey from Dehradun to Delhi. The flight was operated by India-based operator SpiceJet and the fuel was prepared by the CSIR-Indian Institute of Petroleum, Dehradun. The aircraft’s right engine used the fuel, which was a combination of biofuel derived from the Jatropha plant (25 per cent) and aviation turbine fuel (75 per cent). About 330 kg of biojet fuel was consumed by the flight. The fuel has been recognised by the American Standard Testing Method and it meets the specification standards of Pratt & Whitney and Bombardier for commercial application in aircraft.
