Aircraft taxi path guidance and display

摘要

An aircraft taxi path guidance and display system is provided. The aircraft taxi path guidance and display system includes or cooperates with at least one source of aircraft status data, and a source of airport feature data associated with an airport field. The aircraft taxi path guidance and display system includes a processor operationally coupled to the source of aircraft status data and to the source of airport feature data. In response to aircraft status data and airport feature data, the processor predicts undesired deviations from an active surface area (e.g., an excursion). The processor generates corrective action associated with the excursion, and displays symbology that is graphically representative of the corrective action.

主权项

1. A method for displaying aircraft taxi path guidance on a display unit in an aircraft, the method comprising:
obtaining aircraft status data comprising heading data, steering angle and differential speed of the main landing gear; obtaining airport feature data; processing, by a processor, the aircraft status data and the airport feature data to (i) generate a trend line that represents an aircraft predicted taxi path, and (ii) wherein a surface area within the airport in which the aircraft may safely travel comprises an airport active surface area, predict an excursion when an intersection of the aircraft predicted taxi path with a shoulder of an airport active surface area occurs within a predetermined distance threshold; in response to predicting the excursion, generating, corrective action associated with the excursion, wherein the corrective action is based on the differential speed of the main landing gear; and displaying, on the display unit, symbology that is graphically representative of (i) the trend line, and (ii) the corrective action.
