Aircraft Display Synchronization for Environmental Data Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current graphical representation systems in aircraft environments suffer from de-synchronism in data refresh times across different applications, leading to pilot discomfort due to the need for manual switching between screens and inefficient use of graphical resources, resulting in inconsistent and synchronized information presentation.
Innovation Solution
A device that harmonizes and synchronizes the graphical representations by using a reference real-time calculation cycle to refresh and orient environmental data, such as from the TAWS and WXR systems, in conjunction with cartographic data, ensuring consistent display and reducing the shearing effect caused by aircraft heading changes.

Engineering Contradiction Analysis
1Reliability
If multiple independent applications display environmental data on separate screens, then each application can maintain its own data refresh cycle, but the pilot experiences visual discomfort and decision-making challenges due to disparate data presentation
Solution Approach 1:
The patent combines multiple independent graphical representation applications (TAWS, cartographic, meteorological) into a single unified display system. The synchronizing means coordinates these applications to refresh and overlay their respective data on one common screen simultaneously, eliminating the need for multiple separate screens while maintaining data consistency through a shared reference calculation cycle.
Solution Approach 2:
The single display screen serves multiple functions by simultaneously presenting TAWS data, cartographic information, and meteorological data. The synchronizing mechanism enables this multi-functional display by coordinating different data sources and their refresh cycles, allowing the pilot to access diverse environmental information from one unified interface.
2Productivity
If applications use independent calculation cycles, then each application can optimize its data processing, but the graphical representations become de-synchronized and require multiple screens for accurate display
Solution Approach 1:
The synchronizing means acts as an intermediary between independent calculation resources and the display system. It receives data from multiple applications running on independent calculation cycles, coordinates their refresh operations, and overlays them on a single screen. This mediator enables unified display without requiring the applications to share calculation resources, thus maintaining processing efficiency while reducing display complexity.
Solution Approach 2:
The system dynamically coordinates the refresh cycles of multiple applications with different data processing requirements. The synchronizing mechanism adapts to varying calculation cycles by orchestrating data overlay timing, allowing each application to maintain its optimal processing speed while achieving synchronized graphical representation on the single display.
3Measurement precision
If environmental data are refreshed at different intervals, then each data type can be updated at its optimal frequency, but the overlay on a single screen creates visual inconsistency during aircraft turns
Solution Approach 1:
The synchronizing means implements periodic coordination of data refresh operations. It establishes a reference calculation cycle that periodically synchronizes the overlay of environmental data from multiple applications. This periodic synchronization ensures that even though individual applications refresh at different intervals, their graphical representations remain coherent and consistently aligned on the display during aircraft maneuvers.
