Synchronized Range and Time Scales on Avionics Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional avionics display systems lack the ability to provide precise 4D navigation by offering limited situational awareness in the time domain, as they primarily focus on spatial scales with minimal time information, which is inadequate for NextGen operations requiring synchronized performance-based range and time scales.
Innovation Solution
A display system and method that utilize a processor and input device to render symbology representing distance and travel time, automatically updating range and time data in response to user input, allowing for synchronized performance-based range and time scales on a vehicular display system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional avionics display systems provide only spatial scale display, then the display system remains simple and easy to operate, but the situational awareness in the time domain is limited
Solution Approach 1:
The patent combines spatial range data and temporal time data into a single integrated display system. The range scale and time scale are merged into one coherent visual representation, allowing pilots to simultaneously view both spatial and temporal information without requiring separate display systems or interfaces.
Solution Approach 2:
The patent adds the time dimension to the traditional two-dimensional spatial display. By incorporating time scales alongside range rings, the system transforms the display from purely spatial (2D) to spatio-temporal (3D), enabling 4D navigation visualization without substantially increasing device complexity.
2Measurement precision
If synchronized performance based range and time scales are provided, then 4D navigation requirements are met and trajectory management is improved, but the display system complexity increases
Solution Approach 1:
The system implements synchronized updating where changes in range data automatically trigger corresponding time data updates, and vice versa. This feedback mechanism ensures that the range scale and time scale remain consistently aligned, providing precise 4D navigation information while using the existing display infrastructure.
Solution Approach 2:
The display system is designed to serve multiple functions: it displays traditional spatial navigation information through range rings while simultaneously providing temporal information through time scales. This multi-functionality allows the same display system to meet both conventional navigation requirements and NextGen 4D navigation requirements.
3Adaptability or versatility
If performance based range and time scales are synchronized, then situational awareness is enhanced, but the system requires more complex data processing and updating mechanisms
Solution Approach 1:
The system pre-calculates and stores the relationship between range data and time data based on aircraft performance parameters. When the aircraft flies, the system can quickly retrieve and display synchronized range and time scales without requiring complex real-time calculations, thus enhancing situational awareness while keeping data processing complexity manageable.
Data Source
AI summary
A display system and method is provided for deployment on board a vehicle and includes a data source that provides the display system with data indicative of at least time, position, and velocity of the vehicle. The system comprises a monitor, a display included within the monitor for displaying range data indicative of a specific distance and time data indicative of time it takes to travel the specific distance, an input device, and a processor coupled to the monitor and to the input device and configured to (1) render symbology on the display visually representative of the time data and the range data, and (2) update the range data, and correspondingly change the time data in response to the change in range data made via the input device.
