Rotorcraft Flight Path Display Perspective Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visual display systems in rotorcraft struggle to accurately display flight path information relative to the background or terrain, especially during steep ascent or descent, as the fixed perspective view limits the display of flight path information, making it difficult to navigate during take-off and landing in low-visibility conditions.
Innovation Solution
A visual display system that dynamically adjusts the display perspective based on selected flight procedures and current conditions, using a processor to generate display signals that shift the view center and provide a predicted image, allowing for accurate representation of flight path information relative to the terrain, even during aggressive maneuvers.

Engineering Contradiction Analysis
1Reliability
If a fixed perspective view is used in the visual display system, then the display structure is simple and stable, but the flight path information cannot be accurately displayed during steep ascent or descent
Solution Approach 1:
The display system dynamically adjusts the perspective view based on the selected flight procedure and current flight conditions. The processor automatically shifts the view center and generates a predicted image that adapts to steep ascent, descent, or level flight conditions, transforming the fixed display into a dynamic one that maintains accuracy across varying flight regimes.
Solution Approach 2:
The system changes display parameters including view center position, perspective angle, and image prediction based on flight procedure data. By modifying these parameters according to the selected flight procedure, the system accurately represents flight path information relative to terrain without requiring complex mechanical adjustments.
2Loss of information
If the display perspective is shifted to show flight path information during steep ascent or descent, then flight path accuracy is improved, but the display may become less stable or more complex
Solution Approach 1:
The system performs preliminary actions by predicting the future image based on the selected flight procedure and current flight conditions. This predicted image is generated in advance to show where the flight path will be, allowing pilots to anticipate terrain and obstacles ahead rather than reacting to current position only.
Solution Approach 2:
The predicted image acts as an intermediary between the current display and the actual future position. It provides a virtual representation of the flight path relative to terrain, bridging the gap between current display perspective and future flight position, making flight path information intuitive and easy to interpret.
3Adaptability or versatility
If a reactive display centering mode is used that automatically adjusts based on current flight path conditions, then adaptability is improved, but in aggressive flight conditions a less reactive display is desired
Solution Approach 1:
The display system dynamically adjusts the perspective view based on the selected flight procedure and current flight conditions. The processor automatically shifts the view center and generates a predicted image that adapts to steep ascent, descent, or level flight conditions, transforming the fixed display into a dynamic one that maintains accuracy across varying flight regimes.
Solution Approach 2:
The system provides a universal display solution that handles multiple flight conditions (steady flight, aggressive maneuvers, steep ascent, descent) through a single adaptive mechanism. The same processor-based perspective shifting and image prediction functionality serves all flight regimes, eliminating the need for separate reactive and stable display modes.
