Results of the test campaigns

Figure 107 and Figure 108 show the planned trajectory against the flown trajectory

and the computed distance between them. The mean distance is below the tunnel

boundaries (12.35 m), which for this flight were set to 15 m (30x30 m tunnel section).

Distance peaks are relative to the course turnabouts and mainly due to the adverse

meteorological conditions. Flight altitude is plotted in Figure 109, showing that

notwithstanding ascending airstreams, the pilot succeeded in remaining almost all the

time inside the guidance tunnel. Better results could be obtained looking only at the

aircraft behavior during stripe passages.
