Aeronautics and Air Transport Research 7th Framework Programme ...

The Greening of Air Transport
38
individual work package is as compact as
possible and that interfaces among different
work packages can be kept as simple and
effi cient as possible (see also fi gure).
We begin with the selection of weather situations
(WP1). Climate cost functions are determined
for these weather situations (WP2) and
then fed into a fl ight planning tool to calculate
environmentally-friendly fl ight trajectories and
emissions and climate impact along these trajectories
(WP3). Finally, the results are evaluated
and uncertainties are estimated (WP4).
The potential for mitigating the atmospheric
effect of aviation are further explored (WP5)
and how aircraft design can be optimized with
respect to environmentally friendly fl ight routing
is studied (WP6).
The fi ndings of the project will be aggregated
to recommendations for future ATM, aircraft
design and research (WP7). Specifi c WPs on
coordination and exploitation (WP8) and management
of the project (WP9) complement
the above structure.
Expected Results
The expected results are:
- An initial scoping study of expanding an
operational fl ight planning tool by optimisation
against criteria of fuel consumption and
emissions will be performed; the inclusion of
climate cost functions will enable environmentally
friendly fl ight planning with respect
to climate impact;
- The project will, for the fi rst time, quantify
the potential for improvements of ineffi ciencies
in the air transport system with respect
to fuel consumption, emissions and climate
impact due to non-conventional fl ight trajectories
under realistic atmospheric conditions
on a regional and global scale.
- For the fi rst time, 4D climate cost functions
(as functions of latitude, longitude, altitude
and time) will be calculated for realistic
weather situations. These cost functions will
rely on different emission metrics of climate
change, targets being time integrated marginal
Radiative Forcing RF (in analogy to the
Kyoto metric Global Warming Potential) and
temperature change after a given time horizon
(the Global Temperature Potential);
- The project will allow the formulation of specifi
c recommendations for stakeholders on
fl ight planning, aircraft and engine design for
future green aircraft;
- Cooperation will be instigated between
complementary experts required for environmental
fl ight planning, which has the
potential to initiate follow-up joint work in
Clean Sky JTI and SESAR JU.
