Aircraft Path Guidance Panel with Conditional Waypoints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autopilot and flight management systems confuse pilots with extensive textual indications and lack clear graphical representations of current and future actions, making it difficult for them to understand the system's operations.
Innovation Solution
The implementation of display screens with graphical representations showing the lateral and vertical guidance systems' current actions and future intentions, using a path guidance panel with conditional waypoints and a power control bus for remote system monitoring, and an audio distribution system allowing endpoint control of audio content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If extensive textual indications are used to show system status, then information completeness is improved, but pilot understanding and ease of operation deteriorate due to confusion
Solution Approach 1:
The display is segmented into distinct graphical zones: current action indicators showing what the system is doing now, and future action indicators showing what the system will do next. This segmentation separates overlapping information streams that would otherwise confuse the pilot, while maintaining complete system status information through dedicated visual zones for each temporal state.
Solution Approach 2:
The patent transitions from one-dimensional textual indications to two-dimensional graphical representations with spatial differentiation. By using vertical and horizontal positioning, color coding, and graphical icons on the display screen, the system conveys multiple layers of information (current status, future actions, confidence levels) simultaneously without requiring sequential text reading, thereby improving comprehension while maintaining information completeness.
2Adaptability or versatility
If multiple system functions are integrated into one display, then information integration is improved, but display simplicity and ease of operation deteriorate
Solution Approach 1:
Different regions of the display are assigned specific functional qualities: the upper portion displays future action indicators with distinct graphical symbols, while the lower portion shows current action indicators. Each zone uses tailored visual characteristics (icons, colors, positioning) appropriate to its specific information type, allowing integrated multi-function display while maintaining local visual simplicity and reducing overall cognitive load through organized heterogeneity.

AI summary
A flight management system for controlling navigation of an aircraft includes a path guidance panel having at least one mode selector for allowing user selection of guidance mode in which the aircraft is to operate. The system also includes at least one display device having rendered thereon a navigational map. A computer module receives aircraft data from one or more aircraft components, at least one of the aircraft components being a guidance system. The computer module is configured to use information obtained from the guidance system to cause the display device to render on the navigational map a current flight plan path that is the aircraft is following.
