difference between the 1 m Google Earth database and the high resolution layer is clearly

visible in Figure 98.

7.2.2 Second Test Campaign

The second test campaign was a closed circuit over the Verginese airfield. Also in

this case the trajectory was planned using Google Earth but taking into account standard

maneuver rates. Aim of this second test was the verification that the changes applied to

the tunnel interface were appropriate to overcome the problems encountered during the

first test. The installation procedure was repeated following the check list validated

during the first flight.

The new tunnel interface with an augmented screen resolution, better sharpened

images, a new colour palette and readable air data values allowed the pilot to maintain the

aircraft inside the tunnel for almost the entire flight. The circuit is shown in Figure 99,

while the flown trajectory is plotted against the planned one in Figure 100. It is

immediately noticeable that during this flight the pilot remained always inside the
