Route planning and movement of an aircraft on the ground based on a navigation model trained to improve aircraft operational efficiency is provided herein. A system comprises a memory that stores executable components and a processor, operatively coupled to the memory, that executes the executable components that comprise an assessment component, a sensor component, and a route planning component. The assessment component accesses runway data, taxiway data, and gate configuration data associated with an airport. The sensor component collects, from a plurality of sensors, sensor data related to performance data of an aircraft and respective conditions of the runway, the taxiway, and the gate configuration data. The route planning component employs a navigation model that is trained to analyze the sensor data, the runway data, the taxiway data, and the gate configuration data, and generate a taxiing protocol to navigate the aircraft to improve aircraft operational efficiency.

A monitoring system is provided to ensure continued efficient reliable operation of an aircraft drive wheel drive system, preferably an aircraft drive wheel drive system driven by actuating drive system-actuated drive means, designed to drive an aircraft autonomously during ground operations. The monitoring system includes an array of sensor elements capable of obtaining desired information relating to selected drive system operating parameters and performance indicators during aircraft ground operations. The sensor elements are designed to be functionally located externally of drive system components to obtain information during aircraft ground movement under a range of operating conditions. The operating parameters and/or performance indicators to be monitored preferably include at least drive wheel speed and direction, drive means speed, drive means temperature, and drive means clutch engagement. It is contemplated that the monitoring system could be expanded to include sensors for additional drive system parameters and/or performance indicators.

In various examples, live perception from sensors of a vehicle may be leveraged to generate potential paths for the vehicle to navigate an intersection in real-time or near real-time. For example, a deep neural network (DNN) may be trained to compute various outputssuch as heat maps corresponding to key points associated with the intersection, vector fields corresponding to directionality, heading, and offsets with respect to lanes, intensity maps corresponding to widths of lanes, and/or classifications corresponding to line segments of the intersection. The outputs may be decoded and/or otherwise post-processed to reconstruct an intersectionor key points corresponding theretoand to determine proposed or potential paths for navigating the vehicle through the intersection.

The airframe is tiltable relative to a ground surface to form a non-zero tilt angle between the aircraft longitudinal axis and the ground surface.

The present invention relates to a method for guiding an aircraft over an airport taxiway which is carried out by a data-processing device of a guiding system, wherein said method comprises the steps of determining (E1) at least one possible future path of the aircraft according to the topography of the taxiway in the vicinity of the aircraft, receiving (E2) at least one command relating to the path for the aircraft to follow, selecting (E3) a path to follow from said possible future paths that have been determined and, on the basis of said received command, guiding (E4) the aircraft along the selected path to follow. When the aircraft is in a region of the taxiway for free manoeuvring in which said aircraft can move freely, said possible future paths that have been determined are paths that correspond to a set of predefined radii of curvature, said received command is a command that relates to a radius of curvature, and the selected path to follow is the possible future path that corresponds to the requested radius of curvature.
