A head-up display (HUD) is disclosed. The HUD is provided on board an aircraft. The HUD comprises a projector and a combiner. The combiner enables viewing of the world outside of the combiner and also allows viewing of information provided from the projector. A computer is coupled to the projector and provides airport runway and taxiway symbols conformally mapped onto the combiner. Also provided on the combiner is a mapping of virtual airport signs onto the combiner.

What is claimed is: 1. A computing device for use in a head-up display system (HUD) on board an aircraft, the HUD includes a projector, a computing device, a combiner, the combiner enabling viewing of the world outside of the combiner, and allowing viewing of information provided from the projector, the computing device comprising: a display circuit coupled to the projector for causing the projector to provide airport runway and taxiway symbols conformally mapped onto the combiner, and providing a conformal mapping of virtual airport signs at a position onto the combiner where the position corresponds to an actual location of a sign and a text of the sign is reproduced to allow the text of the sign to be readable; a non-conformal region of the combiner for receiving non-conformal information; and wherein the display circuit is configured to provide a hold line icon on the combiner. 2. The computing device of claim 1, wherein an aircraft location signal is received from a location determining device. 3. The computing device of claim 1, wherein an actual location of a sign signal is received from a database. 4. The computing device of claim 1, wherein an aircraft location signal is received from a global positioning system. 5. The computing device of claim 1, wherein the display circuit transmits a line of text information positioned at approximately the same location on the virtual airport signs as on the sign, each line of text information being the same as information on the sign. 6. The computing device of claim 1, wherein the non-conformal region of the combiner provides a plan form mapping of at least a portion of the airport. 7. The computing device of claim 1, wherein the non-conformal region of the combiner provides representations of airport signs. 8. A method of providing a virtual airport sign on an aircraft combiner for a head-up display (HUD), comprising: determining a location of an aircraft; retrieving information from a database relating to a location of an airport feature within a predetermined distance of the aircraft, the airport feature comprising a locations of a sign; conformally mapping the virtual airport sign at a position onto the aircraft combiner of the HUD where the position corresponds to an actual location of the sign displaying a text of the sign onto the aircraft combiner to allow the text of the sign to be readable; and wherein the predetermined distance can be varied. 9. The method of claim 8, further comprising: dividing the combiner into a conformal region and a non-conformal region. 10. The method of claim 9, further comprising: providing a plan form map including airport signs on the non-conformal display region. 11. The method of claim 8, wherein the location of the aircraft is determined using a global positioning system (GPS) receiver. 12. The method of claim 8, further comprising: generating a virtual turn sign for indicating a location of a turn. 13. A system for projecting a virtual airport sign on a combiner of a head-up display (HUD), comprising: a means for determining a location of an aircraft; a means for retrieving geolocated information from a database relating to a location of an airport feature within a predetermined distance of the aircraft, the airport feature comprising a location of an airport sign; a means for conformally mapping the virtual airport sign at a position onto the combiner of the HUD where the position corresponds to an actual location of the airport sign; a means for displaying a text of the sign onto the combiner to allow the text of the sign to be readable; and wherein the predetermined distance can be varied. 14. The system of claim 13, further comprising: a means for dividing the combiner into a conformal region and a non-conformal region. 15. The system of claim 14, further comprising: a means for providing a plan form map including airport signs on the non-conformal display region. 16. The system of claim 13, wherein the location of the aircraft is determined using a global positioning system (GPS) receiver. 17. The method of claim 13, further comprising: a means for generating a virtual turn sign for indicating a location of a turn. 18. The computing device of claim 1, wherein the text of the sign is reproduced to allow the text of the sign to be readable at any real-life distance from the aircraft. 19. The computing device of claim 1, wherein the display circuit is configured to provide a virtual turn signal based on a comparison of an aircraft ground speed to a turn velocity.
