Correlating 2D and 3D Flight Displays with Location Pointers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pilots face confusion and loss of situational awareness due to the dissimilar two-dimensional and three-dimensional representations of terrain on aircraft flight displays, making it difficult to mentally correlate information between traditional enhanced ground proximity warning systems and Synthetic Vision Systems.
Innovation Solution
A system comprising a manual input device, a processing unit, and display units that update image data sets to include location pointer data, allowing pilots to select locations on one image and have corresponding pointers or markers displayed on the other image, enhancing situational awareness by correlating information between dissimilar image types.

Engineering Contradiction Analysis
1Adaptability or versatility
If two-dimensional plan view and three-dimensional egocentric view are used to depict terrain, then comprehensive navigation information is provided, but pilot situational awareness deteriorates due to difficulty in mentally correlating information between dissimilar images
Solution Approach 1:
The patent introduces location pointers as an intermediary element that bridges the two dissimilar image representations. These pointers are displayed on both the two-dimensional plan view and three-dimensional egocentric view, serving as a common reference that helps pilots mentally correlate terrain features across different visual formats, thereby maintaining situational awareness while using comprehensive navigation displays
Solution Approach 2:
The patent employs visual differentiation through color and graphical markers to distinguish corresponding locations across the two image types. By using consistent visual indicators (such as colored pointers or markers) on both displays, the system helps pilots quickly identify and correlate the same geographic location in both two-dimensional and three-dimensional representations, reducing cognitive load and improving situational awareness

AI summary
Present novel and non-trivial system, device, and method for generating location information presented to a pilot are disclosed. A processing unit is configured to receive manual input data representative of one or more selected image location(s) on a first image data set; determine a selected geographic location for each selected image location; and update the second image data set to include location pointer data. As embodied herein, first and second images represented in the first and second image data sets, respectively, could be displayed simultaneously on the same display unit or separately on different display units. Also, the first image and second image could correspond to an egocentric view and a plan view, respectively, or vice-versa. Additionally, the first image data set and/or second image data set could be updated include first and/or second location pointer data, respectively.
