Flying a light aircraft, where the pilot sits atop the surface of the wings, can be rendered more difficult because of the limited visibility underneath.
It would be a real advantage to be able to somehow see through the wings and thus detect earlier other planes approaching or objects on the runway. Jet fighter pilots can wear experimental headsets which display such a 360-degree view, but today’s invention is a more practical version of this idea for ordinary small aeroplanes.
A video camera (red) is aligned, beneath each wing, with the pilot’s downward view direction as shown. The image from the video is then projected (yellow) onto the wing surface, providing the sensation of seeing through the metal.
