Aircraft Vertical Situation Display with Dynamic Resizing by Flight Phase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vertical situation displays (VSDs) in aircraft lack dynamic adjustment capabilities, leading to suboptimal representation of flight path data, particularly in phases with varying altitudes and numerous waypoints, which can obscure important flight information.
Innovation Solution
A dynamic vertical situation display system that automatically adjusts size and aspect ratio based on the current phase of flight and number of waypoints, allowing manual user control and customization, incorporating a processor to generate display data and interface elements for resizing, panning, and zooming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vertical situation display uses a fixed size and aspect ratio, then the display system is simple and stable, but the visualization clarity deteriorates when flight phases or waypoint densities vary
Solution Approach 1:
The display dynamically adjusts its size and aspect ratio based on the current phase of flight and waypoint density. The processor continuously monitors flight data and automatically resizes the vertical situation display to optimize visualization clarity for different flight conditions, transitioning from a static to a dynamic display system.
Solution Approach 2:
The system changes display parameters (size and aspect ratio) based on flight conditions. When the aircraft enters different flight phases or when waypoint density changes, the processor modifies the display parameters to maintain optimal visualization, allowing the same display hardware to adapt to varying operational requirements.
2Quantity of substance
If the display size is increased to show more waypoints, then the information completeness improves, but the ease of operation deteriorates due to reduced manual control flexibility
Solution Approach 1:
The display system serves itself by automatically adjusting its own size and aspect ratio based on the number of waypoints and current flight phase. The processor monitors waypoint density and autonomously resizes the display to show the appropriate amount of information, eliminating the need for manual intervention to optimize the display for different flight conditions.
Solution Approach 2:
The system implements feedback by continuously monitoring flight data including the number of waypoints and current phase of flight. Based on this feedback, the processor automatically adjusts the display size and aspect ratio, creating a closed-loop system that adapts to changing flight conditions without pilot input.
3Productivity
If the display adapts automatically to flight phases, then the productivity improves through better situational awareness, but the device complexity increases due to the need for phase detection and dynamic adjustment
Solution Approach 1:
The existing flight management system and phase detection capabilities are leveraged to serve the additional function of dynamic display adjustment. The same processors and sensors used for flight control and monitoring are also used to determine display parameters, making the system multi-functional without requiring entirely separate systems.
Solution Approach 2:
The processor acts as an intermediary between the flight management system and the display system. It receives flight phase and waypoint data from the flight management system and translates this information into appropriate display size and aspect ratio settings, mediating between raw flight data and visual presentation.
Data Source
AI summary
A system and method for operating a dynamic vertical situation display on an aircraft includes generating display data for a dynamic vertical situation display displayed on a display based upon flight plan data from a flight management system, where the flight plan data includes a plurality of waypoints and one or more phases of flight. A current phase of flight of the aircraft and a number of waypoints currenting displayed on the dynamic vertical situation display on the display is determined, and instructions to dynamically change a size of the dynamic vertical situation display on the display are generated based upon at least one of the number of waypoints currenting displayed on the display and the current phase of flight of the aircraft.
