Modulation of aircraft guidance lights
First Claim
1. An aircraft, comprising:
- a sensor tuned to receive light of a specific range of wavelengths, the light being emitted by one or more taxiway lights and the light from the taxiway lights having an informational signal modulated thereon the informational signal providing the locations of the taxiway lights;
a processing system coupled to the sensor and configured with software to interpret the informational signal received by the sensor; and
program code running on the processing system, the program code configured to determine the location of the aircraft on the taxiway based on the informational signal associated with the light received by the sensor from one or more of the taxiway lights, wherein the program code is configured to conformally map a representation of an outside boundary of a taxiway on a combiner of a HUD to line up closely with an outside view through the combiner the locations of the taxiway lights being used to ensure registration of the representation of the outside boundary with the taxiway lights.

Abstract
An aircraft landing and/or taxiing system has a plurality of landing zone, runway, and/or taxiway lights capable of receiving information signals and transmitting optically signals representative of the information signals. A processing system for providing the information signals to the plurality of lights is also used. The system also comprises a sensor tuned to receive light of a specific range of wavelengths, the light being emitted from the lights. Also, a processing system coupled to the sensor and configured with software to interpret signals received by the sensor is used. Program code runs on the processing system. The program code is configured to determine the location of an aircraft on the taxiway based on the light signal received from one or more of the taxiway lights. Also, the aircraft landing and/or taxiing system utilizes modulated lights to provide information pertinent to aircraft landing and/or taxiing operations.

10. An aircraft taxiing system for a HUD providing an image on a combiner and for use with light being emitted by one or more taxiway lights and the light from the taxiway lights having an information signal modulated thereon, the information signal providing the locations of the taxiway lights, the aircraft taxiing system comprising:
-
a sensor located on an aircraft and tuned to receive a specific range of wavelengths, wherein the sensor receives the light being emitted from the taxiway lights; a processing system coupled to the sensor and configured with software to interpret data related to the information signal associated with the light received by the sensor; and program code running on the processing system, the program code configured to conformally map a representation of an outside boundary of a taxiway on the combiner to line up with an outside view through the combiner using the locations of the taxiway lights determined from the data. - View Dependent Claims (11, 12, 13, 14, 15, 16)
