Air Travel Energy Use

For information about converting the values from one unit of measure to another compatible unit of measure, see Conversion Factors.

Here are the calculated fields:

• Haul Length (HaulLength)

  Input Fields

  Calculations

  If Segment Distance Unit = AirTravelEmssnFctr.Distance Unit then

  if abs(Segment Distance) < AirTravelEmssnFctr.Short-Haul Maximum Distance, then Haul Length = "Short".

  else, if abs(Segment Distance) < AirTravelEmssnFctr.Medium-Haul Maximum Distance, then Haul Length = “Medium”.

  else, if abs(Segment Distance) > AirTravelEmssnFctr.Long-Haul Minimum Distance, then Haul Length = “Long”.

  Input Fields

  • Segment Distance (SegmentDistance)

  • Segment Distance Unit (SegmentDistanceUnit)

  Calculations

  If Segment Distance Unit = “Miles”, then Segment Distance (Miles) = Segment Distance.

  If Segment Distance Unit = “Kilometers”, then Segment Distance (Miles) = Segment Distance/1.60934.

  Input Fields

  • Haul Length (HaulLength)

  Calculations

  If Haul Length = “Long”, then CO2/Passenger-km (kg) = AirTravelEmssnFctr.CO2/Passenger-km for Long-Haul (kg).

  If Haul Length = “Medium”, then CO2/Passenger-km (kg) = AirTravelEmssnFctr.CO2/Passenger-km for Medium-Haul (kg).

  Input Fields

  • Haul Length (HaulLength)

  • Air Travel Emissions Factor (AirTravelEmssnFctr)

  Calculations

  If Haul Length = “Long”, then CO2/Passenger-mile (kg) = AirTravelEmssnFctr.CO2/Passenger-mile for Long-Haul (kg).

  If Haul Length = “Medium”, then CO2/Passenger-mile (kg) = AirTravelEmssnFctr.CO2/Passenger-mile for Medium-Haul (kg).

  If Haul Length = “Short”, then CO2/Passenger-mile (kg) = AirTravelEmssnFctr.CO2/Passenger-mile for Short-Haul (kg).

• N2O/Passenger-km (kg CO2e) (N2oPassengerKmInKgCo2e)

  Input Fields

  • Haul Length (HaulLength)

  • Air Travel Emissions Factor (AirTravelEmssnFctr)

  Calculations

  If Haul Length = “Long”, then N2O/Passenger-km (kg CO2e) = AirTravelEmssnFctr.N2O/Passenger-km for Long-Haul (kg CO2e).

  If Haul Length = “Medium”, then N2O/Passenger-km (kg CO2e) = AirTravelEmssnFctr.N2O/Passenger-km for Medium-Haul (kg CO2e).

  If Haul Length = “Short”, then N2O/Passenger-km (kg CO2e) = AirTravelEmssnFctr.N2O/Passenger-km for Short-Haul (kg CO2e).

• N2O/Passenger-mile (kg CO2e) (N2oPassengerMileInKgCo2e)
