Background & Policy context

Based on the Swiss action plan "Feinstaub", the report of the Federal Commission for Air Quality and results from its own project ECERT, the Federal Office for Civil Aviation (FOCA) increased international activity towards introduction of an aircraft gas turbine particle emission certification.

The FOCA Particle Sampling Project (PSP) helps to better quantify aircraft engine particle emissions and supports the development of measurement methodologies for a future particle emission certification of aircraft engines. Work is done in collaboration with the Institute of Combustion Technology of DLR (German Aerospace Center) and is internationally coordinated with EASA (European Aviation Safety Agency), ICAO (International Civil Aviation Organisation) and SAE (Society of Automotive Engineers).

  • Aircraft operation at airports: Determination of emission factors (mass and number) and emissions of non-volatile and volatile particles from aircraft gas turbines.
  • Emission certification: Applied research for defining a measurement system, which is suitable for determining particle mass and number in a certification process.
  • Determination of emission factors at airports;
  • Definition of a measurement system for definition of measurement system.

The development of a methodology for standardized aircraft engine particle matter emission measurements is done in SAE-E31 (Society of Automotive Engineers, Aircraft Emissions). FOCA is committee member of SAE-E31. The results of systematic particle line loss measurements were directly used for the development and the optimization of a base system by SAE-E31 during the year 2010. Switzerland contributed to a proposal of a system, which serves as the basis for full-scale large engine testing.

Policy implications
