Table 1 Parameters used for calculating emissions from flight bookings
From: Development and implementation of an emission optimization model for passenger flight bookings
| Parameter | Description | Unit |
|---|---|---|
| U | Emission measured in CO2 | kg |
| C | CO2 conversion factor: 3.15 kg CO2 equals 1 kg aviation fuel (JET A1). | kg/kg |
| 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). | – |
