Dynamic In-Flight Navigation Procedure Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-flight navigation procedures are often depicted as non-interactive, pre-composed images that overwhelm pilots with large amounts of irrelevant information, increasing cognitive workload during flight operations, as existing digital displays do not allow real-time filtering or dynamic adjustment based on current operational parameters.
Innovation Solution
A computing device with a presentation interface and user input interface, coupled to a processing device, displays an initial procedure and adjusts it in response to a triggering event to emphasize a predetermined portion of the procedure, dynamically scaling and decluttering the display to focus on relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pre-composed non-interactive images are used to display navigation procedures, then complete navigation information is provided, but cognitive workload increases due to large quantities of irrelevant information
Solution Approach 1:
The display system dynamically adjusts the navigation procedure display based on real-time aircraft operational parameters (altitude, speed, aircraft category). The system transitions from static pre-composed images to dynamic adaptive displays that automatically filter and emphasize relevant information segments, reducing cognitive workload while maintaining information completeness
Solution Approach 2:
The system applies different display qualities and levels of detail to different portions of the navigation procedure based on relevance. Currently active or upcoming procedure segments are displayed with enhanced visibility and detail, while inactive segments are minimized or hidden, allowing pilots to focus on locally relevant information without losing access to complete navigation data
2Loss of information
If detailed navigation procedures are displayed to ensure completeness, then all possible flight path information is available, but the display becomes cluttered and harder to interpret
Solution Approach 1:
The navigation procedure display is segmented into multiple independent sections or layers representing different flight path options and procedure segments. The system selectively activates and displays only the relevant segments based on current operational parameters, allowing complete flight path information to be available in the system while presenting a simplified, non-cluttered view to the pilot
Solution Approach 2:
The system extracts and isolates only the currently relevant navigation information from the complete set of available procedures. By separating relevant from irrelevant information and displaying only the extracted relevant portions, the system maintains complete flight path data in the system while presenting a clean, uncluttered display interface
3Device complexity
If static pre-composed displays are used, then device simplicity is maintained, but real-time adaptation to operational parameters is not possible
Solution Approach 1:
The display system performs self-service by automatically monitoring aircraft operational parameters and autonomously adjusting the navigation procedure display without requiring manual pilot intervention. The system self-adapts to changing flight conditions by filtering and reorganizing displayed information based on real-time data, maintaining simplicity of operation while achieving sophisticated real-time adaptability
Solution Approach 2:
The system implements feedback loops where operational parameters continuously inform display adjustments. Real-time aircraft state data feeds back to the display control logic, which automatically modifies the navigation procedure presentation to match current operational context, enabling adaptability while keeping the interface simple and intuitive
