Optical viewing apparatus for aircraft doorway
First Claim
1. An aircraft, comprising:
- a fuselage defining a lateral width;
a door connected to the fuselage at a lower end of the door so as to open in a downward manner along an arc; and
a viewing device, comprising;
an image receiver for capturing an image of a predetermined spatial area exterior to the door, the predetermined spatial area being at least partially occupied by the door of the aircraft when the door is in an opened position;
an image projector to display the image of the predetermined spatial area, the image projector positioned in a vicinity of an interior of the door of the aircraft thereby allowing a person to activate an opening mechanism of the door of the aircraft while viewing the predetermined spatial area through the image projector; and
an artificial light source to convey light to the predetermined spatial area exterior to the door, the artificial light source being connected to battery back-up power such that the artificial light source is activatable upon a loss of power to the aircraft,wherein the viewing device comprises a passive portion and an active portion, the viewing device comprising a distal lens housing combined with a camera, such that the viewing device continues to operate if the aircraft experiences a loss of power.

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.
