LTO Fuel consumption for landing, takeoff and taxi, measured in kg aviation fuel (JET A1) kg
CCD Fuel consumption for climb, cruise and descent measured in kg aviation fuel (JET A1) per km travel. kg/km
D Distance km
S Sharklet/Winglet-variabel: 0.95/1 L aviation fuel per liter aviation fuel. L/L
F High altitude factor: 1.9 kg CO2 per 1 kg CO2. kg/kg
P Seating configuration (total seats).
B Passenger cabin factor (percentage sold seats).
