All distances used in the calculations are defined as great circle distances (GCD).
g/pkm = grams per (paid) passenger kilometre
CO = carbon monoxide, HC = hydrocarbons (including methane CH4), NOX = nitrogen oxides, CH4 = methane, N2O = nitrous oxide, SO2 = sulphur dioxide,
CO2 = carbon dioxide, CO2eq. = carbon dioxide equivalent, MJ = megajoule
Properties of aviation fuel, used in calculating fuel consumption [l/hkm] and energy consumption [MJ/hkm], [kWh/hkm],
and to complete missing data concerning CO2 and SO2 emissions:
Density: 800 kg/m3			CO2 factor: 3.169 kg/(kg fuel)
Heating value: 43 MJ/kg			SO2 factor: 0.001 kg/(kg fuel)
*Emission factors to estimate CH4 and N2O emissions:
CH4: 0.0005 g/MJ			N2O: 0.002 g/MJ
**GWP100 (global warming potential) factors for calculating CO2 equivalents:
CO2 ~ 1, CH4 ~ 21, N2O ~ 310
