Vertical Situation Display Field-of-View Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft display systems fail to effectively correlate the cockpit field-of-view with the vertical situation display, making it difficult for pilots to visualize and understand the relationship between the aircraft's field-of-view and surrounding terrain.
Innovation Solution
An aircraft display system and method that generates a vertical situation display with graphics indicating the cockpit field-of-view, including markers for the proximal and distal ends of the field-of-view at ground level, allowing pilots to intuitively correlate the field-of-view with the moving map display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional vertical situation display systems are used, then the display provides basic vertical flight path information, but the pilot cannot correlate the moving map display with the vertical situation display because the cockpit field-of-view is not identified on the vertical situation display
Solution Approach 1:
The patent merges the moving map display and vertical situation display by superimposing graphical representations of the cockpit field-of-view (proximal and distal horizon markers) onto the vertical situation display. This integration allows pilots to correlate spatial information from both displays simultaneously without adding separate physical devices or complex additional systems.
Solution Approach 2:
The patent introduces intermediary visual elements (horizon markers and field-of-view graphics) that act as mediators between the moving map display and vertical situation display. These graphical representations serve as a bridge, enabling pilots to mentally correlate the two displays by providing visual reference points that represent the same spatial perspective in both views.
2Loss of information
If multiple displays are produced simultaneously on a single monitor in split-screen or picture-in-picture format, then both displays are visible, but the observer still has difficulty correlating the information provided by the moving map display and the vertical situation display
Solution Approach 1:
The patent creates a graphical copy of the cockpit field-of-view perspective from the moving map display and superimposes it onto the vertical situation display. The proximal and distal horizon markers are essentially visual copies of the field-of-view boundaries, rendered in the vertical display context, allowing pilots to mentally map one display to the other without physical manipulation.
Solution Approach 2:
The patent translates the horizontal field-of-view concept from the moving map display into the vertical dimension of the vertical situation display by using horizon markers that extend vertically. This dimensional transformation allows the same spatial information to be represented in both horizontal and vertical contexts simultaneously.
3Reliability
If the vertical situation display does not identify the cockpit field-of-view, then the display remains simple and clear, but the pilot's vertical situational awareness does not include visual cues regarding objects falling within the cockpit field-of-view
Solution Approach 1:
The patent applies local quality enhancement by adding specific visual cues (horizon markers and field-of-view graphics) only to the portions of the vertical situation display that correspond to the cockpit field-of-view. This targeted enhancement provides necessary spatial context without cluttering the entire display or requiring a complete system redesign.

AI summary
An aircraft display system is provided and configured to render a cockpit display having a field-of-view. The system comprises a monitor and a processor coupled to the monitor and configured to generate a vertical situation display on the monitor. The vertical situation display includes at least one graphic indicative of a region of the terrain encompassed by the field-of-view.
