SYSTEMS AND METHODS FOR PROVIDING OPTIMIZED TAXIING PATH OPERATION FOR AN AIRCRAFT
First Claim
1. A taxiing path optimization system for computing a taxi path of an aircraft using available taxi routes of a corresponding airport, the taxiing path optimization system comprising:
- an interaction means management unit configured for managing interactions between a user and the taxiing path optimization system using an interactive device configured for inputting a taxi clearance;
an aircraft positioning management unit configured for managing positional information of the corresponding airport and aircraft received from a plurality of sources for augmenting an aircraft position by consolidating the aircraft position with the positional information in a complementary fashion; and
a taxi path display unit configured for displaying the taxi path based on the inputted taxi clearance and the augmented aircraft position, wherein the taxi path is automatically computed based on aircraft characteristics or airport capabilities.

Abstract
A taxiing path optimization system is provided for computing a taxi path of an aircraft using available taxi routes of a corresponding airport. An interaction means management unit manages interactions between a user and the taxiing path optimization system using an interactive device for inputting a taxi clearance. An aircraft positioning management unit manages positional information of the corresponding airport and aircraft received from a plurality of sources for augmenting an aircraft position by consolidating the aircraft position with the positional information in a complementary fashion. A taxi path display unit displays the taxi path based on the inputted taxi clearance and the augmented aircraft position, wherein the taxi path is automatically computed based on aircraft characteristics or airport capabilities.

10. A method of computing a taxi route for an aircraft, the taxi route representing an on-ground trajectory of an airport during taxiing operations utilizing a taxiing path optimization system, the method comprising:
-
building a display-independent and geometrically-based database for describing a flow graph of the airport, the database representing a description of all potential taxi ground trajectories for the aircraft; receiving an initial taxi clearance having airport elements, the taxi clearance being inputted by a user or a related system based on information stored in the database; modifying the initial taxi clearance by eliminating ambiguous taxi routes caused by the initial taxi clearance, and by resolving gaps between the airport elements in the initial taxi clearance; and finalizing the taxi route based on the modified taxi clearance for on-ground navigation of the aircraft at the airport. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of computing a taxi route for an aircraft, the taxi route representing an on-ground trajectory of an airport during taxiing operations utilizing a taxiing path optimization system, the method comprising:
-
receiving an initial taxi clearance having a list of taxi clearance elements including at least two airport elements; searching for links between successive pairs of nodes defined by the list of taxi clearance elements using a predetermined algorithm; generating a set of links connecting the nodes based on the searched links; automatically generating at least one airport element for filling in gaps between unconnected airport elements; consolidating the initial taxi clearance with the generated airport elements; and discretizing the set of links into X/Y points as a final taxi route representation for the aircraft. - View Dependent Claims (17, 18, 19, 20, 21)
