Flight control display for use in an aircraft cockpit and in aircraft simulation systems

1. A flight control display which shows a representation of an aircraft projected onto a display screen showing terrain, a horizon and a gamma ladder, wherein:

the observer has a viewing direction, as depicted in the display screen, which is directed along a momentary flight directon of the aircraft;

an aircraft-fixed system of coordinates is uncoupled from said flight direction, such that the aircraft is shown rotated relative to said viewing direction in the display screen, as a function of a momentary approach flow angle of the aircraft;

the terrain is represented as one of a grid pattern and a three-dimensional depiction; and

the terrain, including the horizon, is oriented in said display screen as a function of a relative orientation of a geodetic system of coordinates and an aerodynamic system of coordinates defined by the momentary flight direction of the aircraft.

2. The flight control display according to claim 1 , wherein important orientation points for the pilot are included in the representation of the terrain.

3. The flight control display according to claim 1 , wherein primary control surfaces of the aircraft and their momentary deflections are depicted in the display.

4. The flight control display according to claim 3 , wherein secondary control surfaces and their momentary positions are also depicted.

5. The flight control display according to claim 1 , further comprising a frame which is colored in a predefined color for indicating warnings.

6. An aircraft flight control display comprising a video screen having depicted therein:

a representation of terrain proximate to the aircraft; and

an aircraft, whose spatial orientation defines an aircraft fixed system of axes, and whose direction of movement defines an aerodynamic system of axes; wherein,

the aerodynamic system of axes are depicted in said display with a fixed viewing orientation relative to the video screens;

the aircraft is centered in the video screen;

the direction of movement of the aircraft extends perpendicularly to the screen surface; and

the aircraft fixed system of axes is uncoupled from the aerodynamics system of axes, such that the aircraft is shown rotated relative to said fixed viewing orientation in said display, depending on a momentary approach flow angle of the aircraft.

7. A method of displaying aircraft flight control information, said method comprising:

providing a video display unit having a display screen surface;

displaying on said video display unit, graphic depictions showing:

a representation of terrain proximate to an aircraft for which flight control information is displayed; and

the aircraft, whose spatial orientation defines an aircraft fixed system axes, and whose direction of movement defines an aerodynamic system of axes;

wherein

the aerodynamic system of axes are depicted in said display with a fixed viewing orientation relative to the video screen;

the aircraft is centered in the video screen;

the direction of movement of the aircraft extends perpendicularly to the screen surface; and

the aircraft fixed system of axes is uncoupled from the aerodynamics system of axes, such that the aircraft is shown rotated relative to said fixed viewing orientation in said display, depending on a momentary approach flow angle of the aircraft.

8. The display according to claim 6 , wherein the terrain is depicted with an orientation relative to said video screen, as a function of relative orientation of said aerodynamic system of axes and a geodetic system of axes which is fixed relative to said terrain.

9. The display according to claim 7 , wherein the terrain is depicted with an orientation relative to said display screen, as a function of relative orientation of said aerodynamic system of axes and a geodetic system of axes which is fixed relative to said terrain.
