Abstract
A viewing device for an aircraft includes an image receiver adapted to receive an image of a predetermined spatial area of an exterior of an aircraft, an image projector adapted to display the image of the predetermined spatial area, and an image conduit connecting the image receiver to the image projector. The image receiver is adapted to be positioned on an exterior side of the aircraft below a lateral width of a fuselage of the aircraft while the image projector is adapted to be positioned on an interior side of the aircraft above the lateral width of the fuselage of the aircraft. The image projector is adapted to be positioned at a first predetermined height above a floor on the interior side of the aircraft, consistent with a person's eye level. The image projector is separated from the image receiver by a first predetermined distance.
