Target-Focused Synthetic Perspective Display for Aircraft Approach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern flight deck displays often fail to maintain focus on the intended approach target or object of interest, especially when the aircraft is approaching from the side, leading to confusion and frustration for pilots due to the target momentarily moving out of the synthetic field of view.
Innovation Solution
A flight deck display system that generates a real-time synthetic perspective view of a selected object or location, keeping it focused regardless of the aircraft's position or orientation, by processing aircraft status data and terrain information to render a target-focused display with a designated viewpoint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a forward-looking cockpit viewpoint is used in synthetic vision systems, then the view is intuitive and provides helpful visual information, but the intended approach target or object of interest may move out of the synthetic field of view when the aircraft is approaching from the side
Solution Approach 1:
The display is segmented into multiple functional zones: a primary forward-looking cockpit viewpoint providing intuitive visual information, and a secondary target-focused display ensuring the approach target remains continuously visible. This segmentation allows each zone to serve its specific purpose without compromising the other.
Solution Approach 2:
The system adds a second display dimension or perspective by implementing a target-focused view that independently tracks and centers the approach target, separate from the forward-looking cockpit viewpoint. This dimensional addition ensures target visibility regardless of aircraft orientation.
2Stability of the object's composition
If the synthetic field of view is limited to a forward-looking perspective, then the display maintains a consistent cockpit viewpoint, but the target momentarily moves off the screen during significant turns or side approaches
Solution Approach 1:
The system merges two distinct display perspectives: the stable forward-looking cockpit viewpoint and the dynamic target-focused viewpoint. By combining these views, the system maintains both viewpoint consistency for situational awareness and reliable target focus for approach guidance.
Solution Approach 2:
The target-focused display acts as an intermediary element that bridges the gap between the fixed forward-looking perspective and the need for continuous target visibility. It mediates by independently tracking the target and presenting it in a dedicated view that complements the main cockpit perspective.
3Device complexity
If the display system uses a fixed forward-looking perspective, then the synthetic vision provides a stable reference frame, but pilots experience confusion and frustration when the target moves out of view
Solution Approach 1:
The system creates a copied or duplicate view of the approach target in the target-focused display, separate from the main forward-looking perspective. This copy ensures the target remains visible and centered regardless of aircraft orientation, reducing pilot confusion without significantly increasing system complexity.
Data Source
AI summary
A method for displaying information on a flight deck display element of an aircraft begins by obtaining a user interface command that represents a user-entered selection of a designated target. Relevant data is accessed and processed in response to this command, including aircraft status data for the aircraft, terrain data corresponding to terrain proximate the designated target, and graphics data corresponding to the designated target. Then, a target-focused display is rendered on the flight deck display element. The target-focused display includes a real-time synthetic perspective view of the designated target and the terrain proximate the designated target, wherein content of the target-focused display is influenced by the aircraft status data, the terrain data, and the graphics data.
