Multi-dimensional Flight Display Vector Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft displays are limited in the number of variables they can show or are overcrowded with data, making it difficult for pilots to easily read and understand complex flight information.
Innovation Solution
A multi-dimensional visualization system that uses a single vector with multiple scales to display flight plan data, allowing for the visualization of multiple variables on a single display, with non-linear scaling for certain variables based on flight plan data, enabling easier data analysis and control of aircraft movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple variables are displayed on the vertical situation display, then the information completeness is improved, but the display becomes overcrowded and harder to read
Solution Approach 1:
The patent applies dimensionality change by introducing a non-linear third variable scale that varies based on flight plan data relative to the vector. This allows multiple variables to be displayed simultaneously without overcrowding, as the third variable's scale dynamically adjusts to provide necessary information while maintaining display clarity. The system transitions from a fixed two-dimensional display to a dynamic multi-dimensional representation.
Solution Approach 2:
The patent implements dynamics by making the third variable's scale non-linear and variable based on flight plan data. Rather than using static scales for all variables, the system dynamically adjusts the third variable's scaling factor according to the specific flight plan being displayed, allowing the display to adapt to different flight scenarios and maintain readability while providing comprehensive information.
2Ease of operation
If a single vector is used to represent flight plan data, then the display simplicity is improved, but the ability to represent multiple variables with different scales is limited
Solution Approach 1:
The patent applies universality by making the vertical situation display capable of representing multiple different variable types and scales through a single unified vector representation. The third variable scale is designed to accommodate different flight parameters (such as altitude, speed, or distance) with appropriate non-linear scaling, allowing the same display mechanism to universally represent various flight plan scenarios without requiring multiple specialized displays.
