The use of aviation gasoline is assumed to take place within the LTO-range of domestic flights only (below 3,000 feet). This assumption is a compromise due to a lack of further information and data. | The use of aviation gasoline is assumed to take place within the LTO-range of domestic flights only (below 3,000 feet).

- | Emissions are being estimated by multiplying the kerosene consumption of the flight stage with specific emission factors (EF). Here, emissions of SO2 and H2O are independent from the method used, depending only on the quantity and qualities of the fuel used. In contrast, emissions of NOx, NMVOC, and CO strongly depend on the types of engines, flight elevations, flight stage, etc. and can be estimated more precisely with higher tiers. The emission factors for NOx, CO, and NMVOC are therefore computed within TREMOD AV. | + | Emissions are being estimated by multiplying the kerosene consumption of the flight stage with specific emission factors (EF).

The aviation gasoline (avgas) used is not added to the annual kerosene consumptions but reported separately. As proposed in (IPCC, 2006a), emissions caused by the incineration of avgas are calculated using adapted EF and calorific values following a tier1 approach. Here, a split into national and international shares is not necessary as avgas is supposed to only being used in smaller aircraft operating on domestic routes and within the LTO range. - This conservative assumption leads to a slight overestimation of national emissions.1 | The aviation gasoline (avgas) used is not added to the annual kerosene consumptions but reported separately.
