Airport Moving Map Display for Obscured Areas and Approaching Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional airport moving maps (AMMs) do not display the dimensions of obscured areas by objects within the pilot's field of view or indicate approaching vehicles outside the displayed field of view, leading to potential misjudgments by pilots.
Innovation Solution
The system includes an avionics database and a flight management system with a processor and display that receives and processes AMM data to indicate obscured areas and approaching vehicles by shading or highlighting relevant sections, extending the displayed field of view to include obscured objects and intruders outside the pilot's direct view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional AMM displays only objects within the pilot's field of view, then the display remains simple and easy to interpret, but pilots cannot detect obscured areas or approaching vehicles outside their direct view
Solution Approach 1:
The system extends the display from two dimensions (within field of view) to three dimensions by showing obscured areas and approaching vehicles that exist outside the pilot's direct line of sight. The AMM renders graphical representations of objects and regions that are physically blocked from the pilot's view, adding spatial depth and extendability to the information display.
Solution Approach 2:
The system performs preliminary detection and display of potential hazards before they enter the pilot's field of view or before collisions become imminent. By calculating and displaying obscured areas and approaching vehicles in advance, the system provides early warning that allows pilots to take preventive action.
2Reliability
If the AMM displays comprehensive environmental data including obscured areas and approaching vehicles, then safety is enhanced, but the device complexity increases
Solution Approach 1:
The system introduces an intermediary computational layer that processes sensor data, calculates obscured areas, and determines approaching vehicle trajectories before rendering them on the display. This intermediary processing layer manages the complexity by separating detection, calculation, and display functions, allowing comprehensive safety monitoring without overwhelming the pilot with raw data.
Solution Approach 2:
The system applies different display qualities and levels of detail to different regions of the display. Obscured areas and approaching vehicles are highlighted with specific visual characteristics (such as different colors, patterns, or intensity) to distinguish them from normal field-of-view objects, allowing pilots to quickly identify critical information without processing the entire display uniformly.
3Loss of information
If the AMM does not display dimensions of obscured areas, then the display remains simple, but pilots may mistakenly conclude that objects do not obscure critical areas
Solution Approach 1:
The system uses color variations to encode different types of information about obscured areas and approaching vehicles. Different colors or shading patterns indicate the degree of obscuration, the size of obscured regions, or the urgency of approaching threats, allowing pilots to rapidly assess situational awareness without requiring detailed numerical data.
