Patent Images
1. An Aviation Weather Awareness and Reporting Enhancements (AWARE) system, comprising:
- a database configured to store text and graphic weather data and to store context information including at least one of pilot preferences, aircraft properties and airport properties;
a server that extracts temporally-spatially filtered weather data and context information from the database and uses a Bayesian network (BN) to assess the weather data and context information and issue hazard alerts; and
a client that receives user requests, issues client requests to the server to extract the weather data and context information and displays the filtered weather data and hazard alerts.

Abstract
An Aviation Weather Awareness and Reporting Enhancements (AWARE) system provides situational awareness by effectively filtering, analyzing and visualizing aviation weather data and specific hazard alerts in preflight, in-cockpit and controller applications. The AWARE system includes a temporal-spatial databases that filters weather data and a Bayesian network that assesses specific hazards in the filtered weather data in the context of pilot preferences, aircraft properties and airport properties. The filtered weather data and hazard alerts are then displayed on a client.

39. An Aviation Weather Awareness and Reporting Enhancements (AWARE) system, comprising:
-
a temporal-spatial (T/S) database that stores the text and graphic weather data, and a contextual-information database comprising data selected from at least one of pilot preferences, aircraft properties and airport properties; and
a Bayesian network (BN) defined as a tuple (V,E,P), where V is a set of nodes, E is a set of edges and P is a set of conditional probability distributions, said set of nodes V comprising at least one hazard node whose state determines a hazard alert, said hazard node having at least one parent data node that is instantiated with weather data from the T/S database and at least one parent context node that is instantiated with preferences or properties from the contextual-information databases. - View Dependent Claims (40, 41, 42, 43)

44. An Aviation Weather Awareness and Reporting Enhancements (AWARE) system, comprising:
-
a temporal-spatial (T/S) database that stores the text and graphic weather data, a contextual-information database comprising data selected from at least one of pilot preferences, aircraft properties and airport properties a text and graphics postprocessor (TGP) that integrates filtered text and graphic weather data extracted from the T/S database, said TGP identifying events in the weather text data and assigning icons to those events that are registered to the weather graphic data, a Bayesian network (BN) defined as a tuple (V,E,P), where V is a set of nodes, E is a set of edges and P is a set of conditional probability distributions, that assesses the filtered text and graphic weather data in the context of preferences and properties from the contextual-information database to declare hazard alerts and provide hazard assessment information, and a client that displays the filtered graphic weather data, the overlaid icons and hazard alerts and, for a selected hazard alert, displays the relevant text weather data and hazard assessment information. - View Dependent Claims (45, 46, 47, 48, 49, 50)

51. An Aviation Weather Awareness and Reporting Enhancements (AWARE) system, comprising:
-
An AWARE client configured to receiver user requests, issue client requests and display weather data and hazard alerts;
an AWARE database comprising;
a temporal-spatial (T/S) database that stores the text and graphic weather data, and a contextual-information database comprising data selected from at least one of pilot preferences, aircraft properties and airport properties;
an AWARE server comprising;
a query formulator that issues queries to extract filtered weather data from the T/S database in response to client requests, a text and graphics postprocessor (TGP) that integrates the filtered text and graphic weather data and forwards it to the AWARE client, and a decision support system (DSS) including a Bayesian network (BN) defined as a tuple (V,E,P), where V is a set of nodes, E is a set of edges and P is a set of conditional probability distributions, said set of nodes V being organized in a graph structure in which evidence nodes are the parents to first tier hazard nodes, which are in turn the parents to second tier hazard nodes, said evidence nodes being instantiated with the filtered weather data and relevant preferences and properties from the contextual-information database to determine the state of said first tier hazard nodes, which in turn determine the state of said second tier hazard nodes, the state of said hazard nodes determining the hazard alerts displayed by the client. - View Dependent Claims (52, 53, 54, 55, 56, 57)
