Systems, methods and non-transitory computer readable storage media for airspace management within an airspace region at a node of a peer to peer network having a plurality of nodes and maintaining a blockchain containing a current deconflicted flight schedule for the airspace region. One method includes receiving requests for airspace reservations, each including flight plan data, from other nodes over the peer to peer network, compiling the flight plan data to identify conflicts between the requests and the current deconflicted flight schedule, validating the flight plan data of the requests that do not conflict with the current deconflicted flight schedule to generate validated airspace reservations, creating a block containing the validated airspace reservations and interlinking the block with the blockchain such that the blockchain contains a new deconflicted flight schedule for the airspace region for broadcast to the other nodes over the peer to peer network.

Methods and systems are provided for assisting operation of a vehicle deviating from a desired manner of operation, such as an aircraft deviating from a planned trajectory. One method involves identifying a current aircraft altitude, identifying a current aircraft configuration, determining a recommended flight path from the current aircraft altitude for satisfying an upcoming constraint associated with a reference descent strategy based at least in part on the current aircraft configuration in response to a deviation between the current aircraft altitude a target altitude according to the reference descent strategy, and providing an output influenced by the recommended flight path. The recommended flight path includes a recommended vertical profile and a recommended speed profile, and the recommended flight path is configured to vary at least one of a kinetic energy or a potential energy of the aircraft along the recommended flight path en route to the upcoming constraint.

Disclosed are algorithms and agent-based structures for a system and technique for analyzing and managing the airspace. The technique includes managing bulk properties of large numbers of heterogeneous multidimensional aircraft trajectories in an airspace, for the purpose of maintaining or increasing system safety, and to identify possible phase transition structures to predict when an airspace will approach the limits of its capacity. The paths of the multidimensional aircraft trajectories are continuously recalculated in the presence of changing conditions (traffic, exclusionary airspace, weather, for example) while optimizing performance measures and performing trajectory conflict detection and resolution. Such trajectories are represented as extended objects endowed with pseudo-potential, maintaining objectives for time, acceleration limits, and fuel-efficient paths by bending just enough to accommodate separation.

A system may include at least one processor. The at least one processor may be configured to: obtain air traffic data associated with at least one air traffic target; based at least on the air traffic data, determine at least one estimated wake turbulence trail for each of the at least one air traffic target; and at least one of: (a) generate at least one display image based at least on the at least one estimated wake turbulence trail and output the at least one display image to at least one display for presentation to a user, each of the at least one display image including at least one wake turbulence trail indicator, the at least one wake turbulence trail indicator generated based at least on the at least one estimated wake turbulence trail; or (b) operate the aircraft to avoid the at least one estimated wake turbulence trail.

A method of warning of early rotation of an aircraft during takeoff is disclosed. An improvement in aircraft performance and passenger comfort can be realised by monitoring for signs of early rotation and warning the pilot of such. By detecting when rotation has been commanded by the pilot, and the aircraft nose has started to lift off the ground, when the speed of the aircraft is below a threshold, early rotation can be determined and an auditory warning can mitigate the impact of that on aircraft performance.

An information delivery method is performed by an electric vertical takeoff and landing aircraft (eVTOL) communicating with a management server. The information delivery method includes acquiring itinerary information that indicates an itinerary for a user on board the eVTOL including both a flight utilizing the eVTOL and a ground travel utilizing an automobile from the management server. The information delivery method further includes acquiring position information indicating a current position of the eVTOL. The information delivery method further includes displaying navigation information including a route of the flight, a route of the ground travel, and the current position on a display installed on the eVTOL, or delivering the navigation information to a user terminal of the user.

The transmission of flight instructions from a ground unit to an aircraft comprising an onboard system. The ground unit is configured to generate, on the basis of flight data intended for the aircraft, at least one optical symbol containing a flight instruction. The onboard system comprises an optical reader and a flight management system. The optical reader is configured to read the optical symbol and to transfer the flight instruction contained in the symbol to the flight management system to prepare the flight of the aircraft.

A system and method are provided for monitoring, collecting and aggregating position information from multiple independent data sources to localize a position of an aircraft operating worldwide. The localized position information is provided to one or more end-users or stakeholders in a format for direct integration into one or more mapping and/or situational awareness display applications. Information is collected from a plurality of monitored data sources. Weighted values are applied to certain of the information collected from the plurality of data sources according to known or predictable/determinable static and/or dynamic accuracy errors and latencies of the information provided. A detailed analytic algorithm is applied to provide a probabilistic analysis that results in a resolution of a real-time, or near real-time, aircraft location, as well as an ability to accurately predict an aircraft location along a track at some future time.

A collaborative aviation information collection and distribution system includes a plurality of aircraft data transmitters and an aircraft data processing system. Each aircraft data transmitter is configured to selectively transmit aircraft data associated with a subscribing aircraft. The aircraft data processing system is in operable communication with each of the aircraft data transmitters and includes a data receiver, a data transmitter, and a data processor. The data receiver receives aircraft data transmitted from each of the aircraft transmitters. The data transmitter selectively transmits actionable aircraft data to one or more of the subscribing aircraft or subscribing ground-based users. The data processor determines which of, and when, the one or more subscribing aircraft or subscribing ground-based users should receive actionable aircraft data, generates actionable aircraft data from at least a portion of the received aircraft data, and supplies the generated actionable aircraft data to the data transmitter for transmission.

There is provided a flight trajectory system that estimates contaminant exposure experienced by a flight for scheduling of flight maintenance interventions, comprising: at least one input interface that receives at least one trajectory of a flight comprising flight track points; a storage medium containing executable instructions for executing a flight trajectory algorithm and a database of flight trajectory data; and a computing arrangement coupled to the at least one input interface and the storage medium, wherein the computing arrangement receives the at least one trajectory of the flight and interrogates the database of flight trajectory data to: validate the flight track points, wherein the flight track points are validated based on at least one performance of the flight, generate a fixed trajectory for the flight based on the validated flight track points and the flight trajectory algorithm, and analyze, using a flight trajectory model, the fixed trajectory of the flight to estimate contaminants exposure of the flight on the fixed trajectory for scheduling flight maintenance interventions, and wherein the contaminants comprise at least one of: dust, ice, atmospheric aerosol particles or corrosive gases.
