Pilot-configurable information on a display unit

A flight deck display system comprising:

• a control panel of a flight deck;
• a first display unit installed in said control panel;
• a second display unit installed in a space adjacent to said first display unit;
• a computer system configured to send tactical information to said second display unit in response to a request for tactical information from a pilot;
• and
• a control unit operable by a pilot for sending a request for tactical information to said computer system,
• wherein said second display unit comprises:
• a housing in the shape of a cuboid having external faces, said housing projecting out of and perpendicular to said control panel and disposed within a pilot's primary field of view on the flight deck;
• an image processor housed in said housing, said image processor being programmed to generate image data which is a function of tactical information;
• a liquid crystal display screen affixed to one external face of said housing and operatively coupled to said image processor for displaying an image in a horizontal plane that is perpendicular to said control panel, wherein the image is a function of electronic image data generated by said image processor;
• and
• a light-reflecting viewing surface disposed external to and pivotably coupled to said housing, wherein said viewing surface is arranged at an angular position such that a horizontally disposed image directly projected by said liquid crystal display screen onto said viewing surface is reflected by said viewing surface toward a vantage point of a pilot on the flight deck.
