Technology segments an input flight path into segments based on terrain data, identifies target altitude heights of endpoints of the segments based on the terrain data and a target cruise altitude of an aircraft, identifies local maximas associated with the segments that are arranged in an order along the input flight path, identifies one or more local maximas of the local maximas that represent a dip in altitude from a previous one or more of the local maximas, removes the one or more local maximas from the plurality of local maximas to generate a reduced list of local maximas, sets a plurality of waypoints as the endpoints and the local maximas in the reduced list of local maximas, generates a flight path based at least in part on the plurality of waypoints, and causes the flight path to be provided to the at aircraft.

An unmanned aerial vehicle (UAV) or drone executes a neural network to assist with detecting and responding to attacks. The neural network may monitor, in real time, the data stream from a plurality of onboard sensors during navigation and may communicate with a high-altitude pseudosatellite (HAPS) platform For example, if the neural network detects a cyber-attack but determines that it does not interfere with external communications, it may shift navigation control of the drone to the HAPS.

A technique for building a modified entry trajectory profile for an aircraft to join a holding pattern at an entry waypoint despite the airspace available to build the entry trajectory being limited. In one aspect, instructions are received for an aircraft to join a holding pattern at an entry waypoint according to an entry trajectory profile. An airspace around the holding pattern is divided into sectors using the entry waypoint as a reference point. A discontinuity in the entry trajectory profile can be identified. In response to identifying the discontinuity in the entry trajectory profile, a modified entry trajectory profile can be built by i) determining the sector from which the aircraft would approach the entry waypoint with a current track angle of the aircraft moved to intersect the entry waypoint and with the aircraft pointing at the entry waypoint; and ii) generating the modified entry trajectory profile.

A method includes obtaining data associated with a specified airspace indicating or identifying manned flights within the specified airspace and identifying one or more exclusion zones associated with one or more manned flights within the specified airspace based on the data. Each exclusion zone identifies a volume from which one or more flight vehicles are excluded from operating within the specified airspace. The method also includes modifying each exclusion zone in order to randomly change a shape of exclusion zone and generate one or more modified exclusion zones. In addition, the method includes providing information defining the modified exclusion zone(s) to one or more flight vehicle operators so that the one or more flight vehicle operators are able to avoid operating the flight vehicle(s) in the modified exclusion zone(s). The information defining modified exclusion zone(s) lacks information identifying the manned flights within the exclusion zone(s).

A control system, a navigation system, a monitoring system, a runway incursion system, a navigation system, a guidance system, a safety system, processes, and methods of use are presented. More specifically, and without limitation, the present disclosure relates to an autonomous navigation system, a dynamic path guidance system, an emergency response system, an autonomous vehicle navigation system, processes, and methods of use. More specifically, and without limitation, the present disclosure relates to an airport navigation and safety system.

A system and method for interference detection. The system and method receives flight data comprising a plurality of flights. The system and method identifies a plurality of signal drop events based on at least the flight data. The system and method determines one or more co-located signal drop event subsets based on at least the plurality of signal drop events and filter criteria. The system and method determines one or more interference events based on the one or more co-located signal drop event subsets, wherein each of the one or more co-located signal drop event subsets is based on at least two or more of the plurality of signal drop events.

The present disclosure describes systems and methods for providing real-time holding and diversion information to a pilot of an aircraft. In one aspect, the pilot uses an electronic flight bag (EFB) or a flight management computer (FMC) to display in a GUI the holding and diversion information. For example, the EFB can receive ADS-B data that can be used to determine the location of the aircraft in the holding queue (i.e., the aircraft's queue position) and predict the amount of time before the aircraft will be able to land. The EFB or FMC can also display diversion information regarding one or more alternate locations (e.g., alternate airports) in the GUI. In one aspect, the EFB or FMC calculate a bingo fuel and the time until reaching the bingo fuel and the pilot must divert.

A method for managing taxiing paths of an aircraft includes at least one computer system, the method being implemented by the computer system. The method includes the following steps: editing an initial path; displaying a route of the initial path on a screen using a first route symbolism; obtaining a validation of the initial path; displaying a route of the validated initial path on the screen using a second route symbolism; implementing the validated initial path in a taxiing setpoint of the aircraft. The method further includes an editing process and an independent display process.

A technological improvement to a system for vehicle navigation is provided. The improvement diminishes a contribution to global climate change, e.g., global warming, by generating a flight path (generated flight path) or modifying the flight path (modified flight path) of a vehicle to avoid an atmospheric region in which the vehicle would create a contrail if the vehicle travelled through the atmospheric region.

A method and system for determining and displaying a turn to a heading entry for an aircraft has been developed. First, a preliminary heading selection and a preliminary turn direction are entered into an automated flight control system (AFCS) for an aircraft. The preliminary heading selection and the preliminary turn direction are displayed to a pilot of the aircraft. A subsequent heading selection is entered into the AFCS while the aircraft is engaged in turning to the preliminary heading selection in the preliminary turn direction. A shortest turn radius to the subsequent heading selection is determined. A determination is made if the shortest turn radius to the subsequent heading selection is the same direction and the preliminary turn direction and a notice is displayed to the pilot of the aircraft is the shortest turn radius to the subsequent heading selection is not the same direction and the preliminary turn direction.
