The main goal of the BurnFAIR project was to gain experience and generate data on the regular use of alternative fuels over a long period of time.
In particular, the project aimed at evaluating the consequences on engines health and the potential operational issues that may not have been identified in previous lab-tests and singular flights.
As part of the project, a Lufthansa Airbus A321 operated four daily round flights between Hamburg and Frankfurt, for a period of 6 months, with one engine fuelled with a 50% blend of conventional jet fuel and HEFA synthetic fuel.

From July to December 2011, 1187 flights were performed which used 1557 tons of biofuel blend.
The conclusion of the project was that the biofuel proved its worth in daily flight operation.
