ABSTRACT:
A device to improve the field of vision in aircraft that lack sufficient transparent surface area. The device includes at least one collimator connected to an imaging sensor of the space outside the aircraft. The collimator projects an image in the pilot's field of vision. The image covers both the transparent window surface and the instrument panel of the cockpit. The image coincides with the real image in the field of direct vision produced by the transparent surface. A further image may also be viewed by the pilot through a periscope arrangement.
