Abstract: “This paper presents the work conducted as part of an effort in developing a multidisciplinary assessment framework for trade off study between technical, economic and environmental aspects of alternative jet fuels application specifically in commercial aircraft. At present, empirical prediction method has been explored so as to be the basis in predicting the amount of emissions that have a huge influence towards the environment. An emission prediction model based on Boeing Fuel Flow Method 2 (BFFM2) has been adopted and its accuracy and applicability has been tested on a specified engine model. The model was then used to evaluate and to compare the amount of emission emitted due to the combustion of alternative fuels, namely Camelina- and Jatropha- synthetic paraffinic kerosene (SPK) with the conventional jet fuel, Jet A. With emphasis on emissions of nitrogen oxides (NOx) and carbon monoxide (CO) at take-off and cruise conditions, the results indicate that the alternative fuels manage”
