Results of the test campaigns

111

No further magnetometer calibration was applied with respect to that made inside the

laboratory. The planned trajectory is shown Figure 93. The departure airport was the

Verginese airfield near Ferrara.

During the flight, the pilot, which was not trained before takeoff, had serious

difficulties trying to follow the tunnel indications, probably because of an uncorrected

bias in the tunnel geometry. The position predictor was switched off and no standard

maneuvers was used during planning. In addiction the colour palette was not producing

sufficiently sharp images so the tunnel itself was not clearly distinguishable from the

background. The resulting flown trajectory with respect to the planned one is shown in

Figure 94.

Figure 94: First flight campaign, planned vs flown trajectory

The pilot tried to follow the planned trajectory for the first part (tunnel side was set at

50 m) and then, after exiting the tunnel to reach the following known waypoint, re-

entered the planned trajectory for another small portion of the planned flight. So only the

initial part of the flight has been analyzed, and the results are shown in Figure 95, Figure

96 and Figure 97, where the mean distance between the planned and flown trajectories

was 6125 m. Also altitude plot shows how the pilot was not able to stay inside the

guidance tunnel.
