As of today vehicle fuels may be used if the respective engine and cell are certified for such an operation. For older planes a supplementary technical certificate is provided for gasoline mixtures with less than 1 \% v/v ethanol only, though. Larger admixtures of ethanol may lead to sudden engine malfunction and should be considered as considerable security risks. Major problems are caused by the partially ethanol non-withstanding materials, a necessarily changed stochiometric adjustment of the engine for varying ethanol shares and the tendency for phase separation in the presence of absorbed water. The concepts of the flexible fuel vehicles are only partially applicable in the view of air security.}, language = {en} } @misc{EickmannEschFunkeetal.2014, author = {Eickmann, Matthias and Esch, Thomas and Funke, Harald and Abanteriba, Sylvester and Roosen, Petra}, title = {Biofuels in Aviation - Safety Implications of Bio-Ethanol Usage in General Aviation Aircraft}, year = {2014}, abstract = {Up in the clouds and above fuels and construction materials must be very carefully selected to ensure a smooth flight and touchdown.
