Exhaust emissions from a jet engine powered by sustainable aviation fuel calculated at various cruising altitudes

The article focuses on emission analysis of non-CO2 pollutions from aircraft engines on different flight levels: FL240, FL300 and FL350. The calculation were made based on A320 flight from Berlin to Lisbon at the flight level 350, which was the reference flight level in the analysis. Four sustainable aviation fuel have been taken into consideration, which are biofuel from jatropha and biofuel from camelina in different percentage of fuel: 20% of CSPK and JSPK and 40% of CSPK and JSPK. The results showed, that the lowest emission of carbon monoxide is on the lowest tested flight level for flight on biofuel, and the lowest emission of nitrogen oxides is for Jet A-1 on the lowest tested flight level. Emission of every toxic gas compound has been compared to conventional jet fuel on the flight level 350 to show the differences between flight levels.
