Terminal Chart Magnification via Area Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aeronautical navigation charts, particularly terminal charts, present too much information densely, making it difficult for pilots to easily view and comprehend, and existing zooming methods require multiple steps, clicks, or dedicated buttons, often enlarging unnecessary areas and requiring panning to find the area of interest.
Innovation Solution
A computer-implemented method and apparatus that allows users to select an area of a chart, identify coordinates, and categorize it, then compiles and displays related areas in a magnified format, fitting the display size, to enhance viewing efficiency.

Engineering Contradiction Analysis
1Quantity of substance
If terminal charts display all information densely, then complete navigation data is available, but the chart becomes difficult to view and comprehend
Solution Approach 1:
The terminal chart is divided into multiple selectable areas or regions, each representing a different aspect of navigation information (e.g., airport data, weather, terrain). Users can select specific segments to view in detail rather than displaying all information simultaneously, making the chart more comprehensible while preserving access to complete data.
Solution Approach 2:
The system transitions from a two-dimensional dense display to a multi-dimensional viewing approach by adding temporal and hierarchical dimensions. Information is organized in layers that can be expanded or collapsed, and historical or predictive data is added as additional dimensions, allowing comprehensive information to be accessed without overwhelming the primary display.
2Ease of operation
If traditional zooming methods are used, then area of interest can be enlarged, but multiple steps and clicks are required
Solution Approach 1:
The system pre-processes and pre-organizes chart data into logically grouped areas and categories before user interaction. When a user selects an area, the corresponding magnified view is immediately ready for display, eliminating the need for multiple zoom operations or panning steps that would otherwise be required to locate and view the same information.
Solution Approach 2:
An intermediary layer or index is introduced between the user and the detailed chart data. This intermediary provides a simplified overview or table of contents that maps user selections to specific areas of interest, acting as a mediator that translates high-level user intent into precise chart locations without requiring multiple interaction steps.
3Ease of operation
If traditional zooming enlarges entire chart areas, then viewing is simplified, but unnecessary areas are also enlarged
Solution Approach 1:
The magnification function applies local quality enhancement only to the specific area or feature that the user has selected, rather than uniformly enlarging the entire chart. This allows the display to maintain high detail and readability for the area of interest while keeping other areas at their original scale, thus avoiding the display of unnecessary information.
Solution Approach 2:
The system extracts only the relevant information from the selected area and presents it in a magnified or detailed view, separating it from the rest of the chart. This extraction principle ensures that only necessary information is displayed in enhanced detail, while unrelated areas remain visible at their original scale or are temporarily hidden.

AI summary
The different advantageous embodiments provide a computer implemented method, apparatus, and computer program product for generating a display of magnified information. A selection is received of an area of a chart on a display device to form a selected area through a user input device. Coordinates are identified for the selected area. A category assigned to the selected area is identified using the coordinates identified. Related areas of the chart are identified using the category identified. The selected area and the related areas are compiled to form display information and the display information is displayed on the display device having a selected size.
