Domingos de Azevedo Quadros, F. (author)Global passenger air traffic has doubled in the 13 years prior to 2019, and is expected to double again over the next 20 years or so. Growing demand for aviation is met by a corresponding increase in jet fuel being burned by aircraft, releasing multiple pollutants into the atmosphere. Besides disturbing the Earth’s radiative balance, these...doctoral thesis 2024

Nieuwborg, A.B.D. (author), Hiemstra-van Mastrigt, S. (author), Melles, M. (author), Zekveld, Jan (author), Santema, S.C. (author)The COVID-19 pandemic exposed the existential public health and economic fragilities of the civil aviation industry. To prevent future public health disruptions, the civil aviation industry is gaining interest in becoming more “resilient” but rarely elaborates on its meaning, hampering decision-making and strategy development. When looking into...review 2023

Maruhashi, J. (author), Mertens, Mariano (author), Grewe, V. (author), Dedoussi, I.C. (author)Aviation’s contribution to anthropogenic global warming is estimated to be between 3 – 5% [1]. This assessment comprises two contributions: the well understood atmospheric impact of carbon dioxide (CO2) and the more uncertain non-CO2 effects. The latter pertain to persistent contrails and pollutants like nitrogen oxides (NOx), water vapor (H2O),...abstract 2023

van Oosterom, S.J.M. (author), Mitici, M.A. (author)Recent advances in battery technology have opened the possibility for short-haul electric flight. This is particularly attractive for commuter airlines that operate in remote regions such as archipelagos or Nordic fjords where the geography impedes other means of transportation. In this paper we address the question of how to optimize the...journal article 2023

Maas, J.B. (author)Safety is crucial in aviation. This includes the category of General Aviation, which consists of flights that are not performed by commercial airliners. Many of these vehicles are small in comparison to the aircraft used for commercial transport, providing seats for two or four persons. Despite their limited size, accidents involving General...doctoral thesis 2022

Dahlmann, K. (author), Grewe, V. (author), Matthes, S. (author), Yamashita, H. (author)Climate impact of anthropogenic activities is more and more of public concern. But while CO<sub>2</sub> emissions are accounted in emissions trading and mitigation plans, emissions of non-CO<sub>2</sub> components contributing to climate change receive much less attention. One of the anthropogenic emission sectors, where non-CO<sub>2</sub>...journal article 2022
