Melkert, J.A. Faculty Aerospace Engineering Department Aerodynamics, Wind Energy & Propulsion Date 2011-07-31 Abstract The radiative forcing caused by the emissions of jet aircraft is calculated using data from an aircraft performance model. Data from the performance model is needed to calculate the emissions of the aircraft. The sensitivity function and lifetime of the emitted gasses and particles are used to calculate the integrated radiative forcing of the flight of an aircraft. Analysis of a single flight using different fuels and with different cruising altitudes revealed that contrails and aviation induced cirrus cause the largest integrated radiative forcing. This leads to lowest integrated radiative forcing for a cruise altitude of 6 km for both Jet A-1 and Hydrotreated Renewable Jet fuel (HRJ). If contrails and cirrus are omitted the best cruise altitude from the calculated set for Jet A-1 is 11 km while for HRJ 6 km still leads to the lowest integrated radiative forcing.
