When the test pilot of the Airbus A380 lifted off for the first time from the runway, the sole “in vitro” test in a wind tunnel that had been performed, was on a small miniaturised model (scale 1/39). Prior to that, the whole airplane had been designed and tested “in silico” with the use of computational fluid dynamics, which is a major tool for aerodynamic shape design (Figure 1).
