Abstract: A method of providing taxi time information for an airport includes receiving, at a computing system from a device, a request for taxi time information associated with an airport. The method includes determining, at the computing system based on aircraft location information data from a set of aircraft, taxi time information for the airport for a time window. The set of aircraft include aircraft that taxied at the airport within the time window. The time window is less than or equal to one day. The method also includes sending the taxi time information associated with the airport from the computing system to the device.

Abstract: A method is provided for supporting taxi operation of an aircraft. The method includes accessing information that describes a taxi operation of the aircraft at an airport, for a flight of the aircraft. The method includes determining a recommendation for reduced-engine taxi operation of the aircraft based on the information. The recommendation divides the reduced-engine taxi operation into steps including reduced-engine and all-engines steps. A route for the taxi operation is plotted on a diagram of the airport, the route is annotated with an indication of the recommendation for the taxi operation, and a graphical user interface (GUI) is generated that includes the diagram with the route and the indication of the recommendation. The indication of the recommendation includes indications of the steps into which the reduced-engine taxi operation is divided, and the route is annotated to indicate segments of the route over which the steps are performed.
