Project REACT4C

REACT4C is currently in it's second year, after it was started in January 2010 with a kick-off event in Munich.

The project, coordianted by the DLR-Institute of Atmospheric Physics, is funded until 2013 by the European Commission within the 7th Framework Programme (grant number ACP8-GA-2009-233772).

The REACT4C Consortium is composed of a total of eight partners.

The collaborative project REACT4C (Reducing Emissions from Aviation by Changing Trajectories for the benefit of Climate) has the objectives:

  1. to explore the feasibility of adopting flight altitudes and flight routes that lead to reduced fuel consumption and emissions, and lessen the environmental impact;
  2. to estimate the overall global effect of such ATM measures in terms of climate change.
For a set of typical weather situations, 4D (location and time) cost functions will be determined that reflect the environmental and climate impact of aviation emissions. Current operational flight planning tools will be extended to account for environmental effects via these cost functions. Flight trajectories will be calculated for several optimisation targets: operational, economic and environmental. The associated impacts on the environment will be calculated. Practical rules for an environmentally friendly flight planning will be deduced.

Concepts of future (green) aircraft that will be adapted and optimised for the new environmentally compatible flight routing will be developed and the associated mitigation gain of such aircraft will be estimated in terms of environmental and climatic impact.

Finally, the results will be disseminated to stakeholders in the aviation sector, the science community and the general public, and the results will be prepared for further exploitation.
