Emissions testing prospects for 2023 

As most of our active followers know, our research group is responsible for the operation, maintenance and optimization of the Swiss Mobile Aircraft Emission Measurement System (SMARTEMIS). Typically, the system is installed in test cell 1 at SR Technics, located at Zurich Airport. In 2022 however, the SR Technics management decided to reactivate their second … Read more

Aircraft engines: Idle/taxi gaseous emissions

The International Civil Aviation Organization (ICAO) requires that engines of maximum rated thrust greater than 26.7kN be certified for their emission performance[1]. For certification, ICAO defined four power modes in an aircraft’s landing-take-off (LTO) cycle as emission test points. These modes include idle/taxi at 7% of the maximum rated thrust (Foo), approach at 30% Foo, … Read more

Studying the Interactions of Harmful Volatile Organic Compounds with Soot Particles using Dynamic Vapour Sorption

Written by: Jon G. Bell (belj@zhaw.ch) Volatile organic compounds (VOCs), such as benzene and formaldehyde, are characterised by high vapour pressures and, therefore, can easily adsorb to the surface of airborne soot particles, accumulating at the vapour-solid soot interface, within pores, or between the carbon core turbostratic graphene layers. These VOC-loaded, nanometric particles are extremely … Read more

ICAO adopts net-zero carbon emissions goal for international aviation

Written by: Thomas Rötger On 7 October 2022, at the end of 2 weeks of negotiations during the 41st ICAO Assembly, the 193 ICAO Member States took the historic decision to adopt a collective long-term global aspirational goal (LTAG) of net-zero carbon emissions of international aviation by 2050. This resolution was based upon a report on the … Read more

Conference Report: 5th International Conference on Transport, Atmosphere, Climate – TAC-5

A long-awaited return The previous installment of the TAC conferences, TAC-4, was the best conference I attended during my PhD back in 2015. A perfect combination of topics and social activities in a small Bavarian town away from touristy temptations. Naturally, TAC-5 had been on my radar, and it was initially supposed to follow the … Read more
