Aircraft Efficiency Data from Lee et al. (2004)

File Source Aircraft Efficiency Data from IEA (2009).xlsx Figure 2 in Lee et al. (2004) Aircraft Efficiency Data Lee et al (2004).xlsx Figure 7.2 in IEA (2009) Data includes the performance metrics: Energy Intensity [MJ/RPK] ("overall efficiency") for commercial passenger aircraft introduced from 1955-2016. Note: This data was first used in the earlier publication Lee et al. (2001) in Figure 10. It is frequently reproduced, most prominently as Figure 7.2 in the 2009 IEA report Transport, Energy and CO2 (see file Figure 7-2 IEA (2009).pdf, reproduced under CC BY 4.0). For a dataset using MJ/ASK ("Energy Use"), see Aircraft Efficiency Data from Babikian et al. (2002).
