Aircraft Design for Reduced Climate Impact

Abstract

xemissions are less severe and persistent contrail formation is less likely. By considering these altitude eects and additionally applying climate impact reduction technologies, impacts can be reduced by 45-70% with simultaneous direct operating cost savings of 0.6%. Uncertainty is assessed, demonstrating that relative climate impact savings can be expected despite large scientic uncertainties. Additionally, operating cost savings are predicted over a wide range of fuel prices. Strategies for improving climate performance of existing aircraft are also explored, revealing potential climate impact savings of 20-40%, traded for a 2% increase in total operating costs and reduced maximum range.
