Aircraft Navigation Display Personalized Database Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flight management systems face challenges in efficiently accessing and displaying navigation-aid data to pilots, leading to increased workload and risk due to the time-consuming nature of consulting paper documents or electronic flight bags, which are disconnected from the flight management system.
Innovation Solution
A device with a personalized database and extraction means that stores and displays navigation-aid data, allowing pilots to select and display relevant information based on geographic zones, validity periods, and visibility slots, integrated with the flight management system to minimize pilot workload and ensure up-to-date information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation-aid data are stored in paper documents or disconnected electronic flight bags, then data storage capacity is sufficient, but access time increases and pilot workload increases
Solution Approach 1:
The patent merges the navigation-aid data storage with the flight management system by integrating a personalized database into the FMS architecture. This allows pilots to access navigation-aid data through the same interface used for flight plan management, eliminating the need to consult separate paper documents or disconnected electronic devices, thereby reducing access time and workload.
Solution Approach 2:
The patent introduces extraction means as an intermediary component that automatically retrieves relevant navigation-aid data from the personalized database based on the current flight context. This intermediary filters and presents only the necessary information to pilots, reducing the cognitive load of searching through大量 data while maintaining comprehensive data availability.
2Loss of information
If all navigation-aid data are displayed on the navigation display, then information completeness is improved, but display overload occurs and readability decreases
Solution Approach 1:
The patent applies the extraction principle by implementing extraction means that selectively retrieve and display only the navigation-aid data relevant to the current flight phase and context. This filtering mechanism removes unnecessary information from the display, preventing overload while maintaining completeness of essential data. The system extracts data based on geographic zones, validity periods, and visibility slots criteria.
Solution Approach 2:
The patent implements local quality by allowing different types of navigation-aid data to be displayed with different priorities and formats depending on their relevance to the current flight situation. The system adapts the display content and presentation based on the specific flight context, ensuring that critical information is prominently displayed while less relevant information is minimized or omitted.
3Ease of operation
If additional displays are added to show navigation-aid data, then information accessibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing the navigation display to serve multiple functions: displaying flight plan information, navigation-aid data, and situational awareness data all through a single integrated interface. The personalized database and extraction means enable the existing display to dynamically adapt its content based on flight context, eliminating the need for additional dedicated displays while maintaining comprehensive information accessibility.
Data Source
AI summary
A device for aiding the flight management of an aircraft includes a navigation display, a personalized database capable of storing navigation-aid data, each datum comprising a classification type representative of a family or of one or more categories of navigation-aid data, one or more periods of validity of the said datum, information relating to at least one geographic zone of the said datum, one graphic and/or textual representation of the said datum, selection means allowing an operator to choose one (or more) type(s) of classification, called selected type(s), extraction means capable of extracting from the personalized database the navigation-aid datum or data called extracted data of which the type is equal to at least one selected type, of which at least one geographic zone is situated at a distance, from the flight plan or from the aircraft, that is less than a predetermined maximum distance and of which at least one period of validity verifies a predefined display time criterion, the said extraction means transmitting the said extracted datum or data to the said navigation display capable of displaying the representations of the said extracted data.
