Methods and systems are provided for displaying an unusual attitude of an aircraft in a head-up display system. The system comprises a projection unit configured to project the unusual attitude of the aircraft and a processor coupled to the LCD projection unit. The processor is configured to control the LCD projection unit during the unusual attitude of the aircraft to produce an attitude indicator of the aircraft and a horizon symbol. The horizon symbol divides the attitude indicator into a first region having a first display characteristic and a second region having a second display characteristic different from the first display characteristic. The first display characteristic is substantially uniform throughout the first region, and the first region indicates a ground with respect to the aircraft.

What is claimed is: 1. A head-up display (HUD) system for displaying an attitude of an aircraft, comprising: a projection unit configured to project a flight environment; and a processor coupled to the projection unit and configured to: generate the flight environment, including a horizon symbol dividing the attitude indicator into a first region indicating the ground with respect to the aircraft and a second region indicating the sky with respect to the aircraft, overlay an attitude indicator onto the flight environment, and manipulate the flight environment associated with the attitude indicator to indicate the attitude of the aircraft while retaining at least 20% of each of the first region and second region irrespective of an actual attitude of the aircraft. 2. The HUD system according to claim 1, wherein the processor is further configured to display a first pattern as the first region and a second, differing pattern as the second region. 3. The HUD system according to claim 1, wherein the processor is further configured to display a first shading as the first region and a second, differing shading as the second region. 4. The HUD system according to claim 1, wherein the processor is further configured to display a first color as the first region and a second, differing color as the second region. 5. The HUD system according to claim 1, wherein the processor is further configured to generate: an aircraft reference symbol laterally centered in the attitude indicator for indicating an orientation of the aircraft, and a pitch ladder symbol positioned in the attitude indicator with respect to the aircraft reference symbol, the pitch ladder symbol comprising a plurality of pitch lines, each of the plurality of pitch lines indicating a pitch angle. 6. The HUD system according to claim 5, wherein each of the plurality of pitch lines is positioned at a line angle with respect to the horizon symbol, the line angles of said plurality of pitch lines progressively increasing as the pitch angles increase. 7. The HUD system according to claim 1, wherein the projection unit comprises a Liquid Crystal Display (LCD). 8. The HUD system according to claim 4, wherein the first color is a green monochromatic color. 9. A head-up display (HUD) system for displaying an attitude of an aircraft, comprising: a combiner; a projection unit configured to project a flight environment; and a processor coupled to the projection unit and configured to: generate the flight environment, including a horizon symbol dividing the attitude indicator into a first region indicating the ground with respect to the aircraft and a second region indicating the sky with respect to the aircraft, overlay an attitude indicator onto the flight environment, and manipulate the flight environment associated with the attitude indicator to indicate the attitude of the aircraft while retaining at least 20% of each of the first region and second region irrespective of an actual attitude of the aircraft. 10. The HUD system according to claim 9, wherein the processor is further configured to display a first pattern as the first region and a second, differing pattern as the second region. 11. The HUD system according to claim 9, wherein the processor is further configured to display a first shading as the first region and a second, differing shading as the second region. 12. The HUD system according to claim 9, wherein the processor is further configured to display a first color as the first region and a second, differing color as the second region. 13. The HUD system according to claim 9, wherein the processor is further configured to generate: an aircraft reference symbol laterally centered in the attitude indicator for indicating an orientation of the aircraft, and a pitch ladder symbol positioned in the attitude indicator with respect to the aircraft reference symbol, the pitch ladder symbol comprising a plurality of pitch lines, each of the plurality of pitch lines indicating a pitch angle. 14. The HUD system according to claim 13, wherein each of the plurality of pitch lines is positioned at a line angle with respect to the horizon symbol, the line angles of the plurality of pitch lines progressively increasing as the pitch angles increase. 15. The HUD system according to claim 9, wherein the projection unit comprises a Liquid Crystal Display (LCD). 16. The HUD system according to claim 12, wherein the first color is a green monochromatic color.
