In NFR category 1.A.3.a ii (ii) - Domestic Civil Aviation: Cruise emissions from domestic flights between German airports during cruise stage (above 3,000 feet of altitude) are reported.
In the following, information on sub-category specific activity data, (implied) emission factors and emission estimates are provided.
Methodology
Actitvity Data
Specific jet kerosene consumption during LTO-stage is calculated within TREMOD AV as described in the superordinate chapter.

Emission factors
All country specific emission factors used for emission reporting were basically ascertained within UBA project FKZ 360 16 029 3) and have since then been compiled, revised and maintained in TREMOD AV 4).
For more information, please see the superordinate chapter on civil aviation.

Trend discussion for Key Sources
NFR 1.A.3.a ii (ii) - Domestic Civil Aviation - Cruise is not included in the national emission totals and hence not included in the key category analysis.
Recalculations
Activity data have been revised for all years within TREMOD AV to keep in line with information available from the 2019 EMEP/EEA Guidebook 5) and Eurocontrol's AEM model 6).

In parallel, the majority of country-specific emission factors has been revised within TREMOD AV based on information available from the 2019 EMEP/EEA Guidebook 7) and Eurocontrol's AEM model 8).
