Display of airport signs on head-up display
First Claim
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.

Abstract
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.

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. - View Dependent Claims (9, 10, 11, 12)

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. - View Dependent Claims (14, 15, 16, 17)
