Robustness of climate-optimized trajectories and mitigation Potential: flying atm4e

Aviation can reduce its climate impact by controlling its CO2-emission and non-CO2 effects, e.g. aviation-induced contrail-cirrus and ozone caused by nitrogen oxide emissions. One option is the implementation of operational measures which aim to avoid those atmospheric regions that are in particular sensitive to non-CO2 aviation effects, e.g....

The contribution of aviation nox emissions to climate change

The contribution of aviation to anthropogenic climate change results from CO2 and non-CO2 emissions. Latter comprises emissions of nitrogen oxides, water vapour, and aerosols as well as contrail and contrail-cirrus effects. A series of updates can be noted in recent studies related to the effects of NOx-emissions; the inclusion of two physical...

Comparison of various aircraft routing strategies using the air traffic simulation model airtraf 2.0

A climate-optimized routing is expected as an operational measure to reduce the climate impact of aviation, whereas this routing causes extra aircraft operating costs. This study performs some air traffic simulations of nine aircraft routing strategies which include the climate-optimized routing, and examines characteristics of those routings. A...

Assessing the climate impact of formation flights

An operational measure to aim for mitigation of aviation climate impact that is inspired by migrant birds is to fly in aerodynamic formation. This operational measure adapted to human aircraft would eventually save fuel and is, therefore, expected to reduce the climate impact of aviation. As this method changes beside the total emission also the...
