Aircraft Collision Avoidance Vertical Plane Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft piloting systems require pilots to constantly switch between screens for collision avoidance information, increasing workload and potentially leading to ineffective maneuvers due to lack of integrated vertical and horizontal representation, especially in dense air traffic scenarios.
Innovation Solution
A method and device that display a vertical plane representation on an aircraft's screen, including a system of axes and symbols, automatically detecting nearby aircraft and generating warning signals and avoidance information, allowing pilots to visualize and respond to collision risks within the same display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic warnings are displayed on separate horizontal representation screen and flight screen, then information can be organized by function, but pilot workload increases due to constant attention switching between screens
Solution Approach 1:
The patent merges the horizontal representation screen and flight screen into a single integrated display that shows both navigation display information and primary flight display information simultaneously. This allows the pilot to view traffic warnings, terrain information, and flight parameters on one screen without switching attention between multiple screens, thereby reducing workload while maintaining comprehensive information organization.
Solution Approach 2:
The patent introduces a vertical dimension to the display by showing a vertical plane representation that includes altitude information, terrain elevation, and vertical position of surrounding aircraft. This additional vertical dimension allows the pilot to assess collision risks in three-dimensional space without needing to switch between separate horizontal and vertical displays, integrating multiple information types into a unified view.
2Ease of operation
If avoidance command is displayed only on flight screen, then flight parameters can be clearly shown, but pilot cannot quickly assess vertical position and terrain context during avoidance maneuver
Solution Approach 1:
The patent combines the avoidance command display with vertical position and terrain information on the same integrated display. The avoidance command is shown in the context of the vertical plane representation, allowing the pilot to see the recommended vertical speed or flight path angle alongside the current vertical position, terrain elevation, and position of surrounding aircraft, enabling quick assessment without switching screens.
Solution Approach 2:
The patent displays the avoidance command within the vertical plane representation, adding the vertical dimension context directly to the command information. This allows the pilot to understand the avoidance maneuver in terms of vertical position, altitude change, and terrain clearance simultaneously, providing comprehensive spatial context for the avoidance action.
3Ease of operation
If standard horizontal representation is used, then navigation display is simple and clear, but no correlation exists with terrain information and vertical position context
Solution Approach 1:
The patent overlays terrain information and vertical position data onto the navigation display by introducing a vertical plane representation. This allows the horizontal navigation display to be enhanced with vertical context, showing terrain elevation, aircraft altitude, and vertical position of surrounding aircraft in relation to the horizontal navigation information, creating a integrated three-dimensional situational awareness without abandoning the simplicity of the horizontal display.
