Japan Airlines (JAL) became the first airline to conduct a demonstration flight using a sustainable biofuel primarily refined from the energy crop, camelina. It was also the first demo flight using a combination of three sustainable biofuel feedstocks, as well as the first one using Pratt & Whitney engines. The results of the flight are expected to conclusively confirm the second-generation biofuel’s operational performance capabilities and potential commercial viability.
The approximately one and half-hour demo flight using a JAL-owned Boeing 747-300 aircraft, carrying no passengers or payload, took off from Haneda Airport, Tokyo at 11:50am (JST). A blend of 50% biofuel and 50% traditional Jet-A jet (kerosene) fuel was tested in the No.3 engine (middle right), one of the aircraft’s four Pratt & Whitney JT9D engines. No modifications to the aircraft or engine were required for biofuel, which is a ‘drop-in’ replacement for petroleum-based fuel.
Data recorded on the aircraft will now be analyzed to determine if equivalent engine performance was seen from the biofuel blend compared to typical Jet A fuel. The initial analysis of the data will take several weeks and will be conducted by team members from Boeing, Japan Airlines, and Pratt& Whitney.
