Keywords: aeronautics, CFD, Reynolds number, scaling, corrections

CFD calculations have been performed and compared with wind tunnel measurements and semi-empirical methods in order to identify Reynolds number effects on a transonic transport aircraft. The calculations have been done using the CFD solver Edge and the wind tunnel measurements have been done at the European Transonic Wind-tunnel.
