Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern avionics display systems lack predictive visual guidance for pilots executing a safe landing after an engine failure, as they do not effectively display potential landing sites resulting from various aircraft configurations in a conformal, three-dimensional graphical format.
Innovation Solution
An avionics display system that processes avionics data to determine the current aircraft configuration, predict landing sites based on different configurations, and display predictive cues on a three-dimensional graphical terrain display, including symbols and text indicating potential landing locations associated with various lift-to-drag ratio alterations.

Engineering Contradiction Analysis
1Quantity of substance
If modern avionics display systems display considerable amount of useful information, then information availability is improved, but predictive visual guidance for landing sites is still lacking
Solution Approach 1:
The system performs preliminary calculations to predict multiple potential landing sites based on current aircraft configuration and various configuration changes. These predicted landing sites are displayed in advance to the pilot, allowing proactive decision-making about configuration changes before they are actually made, rather than reacting after the fact.
Solution Approach 2:
The system adds a new dimension of predictive information to the traditional avionics display by showing not just current position and terrain, but also predicted landing sites for different configurations. This transforms the display from a static representation to a dynamic predictive tool that shows multiple possible outcomes.
2Ease of operation
If pilots make various aircraft configuration changes during glide landing, then landing control is improved, but landing location predictability worsens
Solution Approach 1:
The system provides feedback to the pilot by displaying predicted landing sites for different configuration options. This allows the pilot to see the consequence of each potential configuration change on the landing location, enabling informed decision-making about which configuration to select based on the desired landing area.
Solution Approach 2:
The system calculates and displays multiple predicted landing sites in advance for different configuration scenarios, allowing the pilot to plan configuration changes proactively rather than reactively, improving both control and predictability.
3Productivity
If aircraft configuration changes are made during glide, then glide performance is optimized, but landing site location changes
Solution Approach 1:
The system adds the dimension of predictive landing site visualization to show how different configuration choices affect landing location. This allows pilots to optimize glide performance while simultaneously understanding the impact on landing site, making informed trade-offs.
Solution Approach 2:
The system provides immediate visual feedback showing the relationship between configuration changes and resulting landing site locations, enabling pilots to make real-time decisions that balance glide performance optimization with landing site selection.
