Electronic Flight Strip Runway Incursion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air traffic controllers lack adequate tools to rapidly detect and correct runway incursions, which can lead to dangerous situations due to inadequate real-time feedback in current paper-based flight strip systems.
Innovation Solution
An electronic flight strip system that combines position data from surveillance systems with geofencing to provide real-time feedback and visual/aural warnings for unauthorized aircraft entries, maintaining the existing workflow while enabling digital manipulation and context-based interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper-based flight strip systems are used, then the existing workflow is simple and familiar to controllers, but real-time feedback capability is inadequate and runway incursion detection is slow
Solution Approach 1:
The system implements real-time feedback by continuously monitoring aircraft position data from surveillance systems and comparing it with authorized flight strip data. When an aircraft deviates from its authorized path or enters a protected area without proper clearance, the system immediately alerts the controller through visual and audible warnings, enabling rapid detection and correction of runway incursions.
Solution Approach 2:
The patent replaces the mechanical paper-based flight strip system with an electronic system that automatically processes position data. Instead of manually tracking paper strips, the system uses digital representation of flight strips combined with automated position monitoring from surveillance systems, eliminating the time delay inherent in manual paper-based tracking.
2Reliability
If electronic flight strip system with real-time monitoring is implemented, then runway incursion detection capability is improved, but system complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating multiple capabilities into a single platform: electronic flight strip display, automated position monitoring, geofence management, and real-time alerting. This consolidates what would otherwise require separate systems into one unified solution, managing complexity through functional integration rather than proliferation of separate components.
Solution Approach 2:
The system performs self-service by automatically monitoring aircraft positions and comparing them against authorized flight paths without requiring manual intervention. The electronic flight strip system autonomously detects incursions and generates alerts, reducing the operational burden on controllers while maintaining high reliability through automated surveillance and analysis.
3Measurement precision
If geofencing and automated position monitoring are used, then detection precision is improved, but information processing requirements increase
Solution Approach 1:
The system extracts only the critical position data elements needed for incursion detection from the overall surveillance data stream. By focusing specifically on aircraft position coordinates and comparing them against geofence boundaries and authorized flight paths, the system achieves high detection precision while minimizing data processing requirements by eliminating unnecessary information.
Data Source
AI summary
An electronic flight strip system and method of detecting and indicating runway incursions are disclosed. One such method receives an aircraft location, compares the location to a geofenced area, and generates an indication on the touchscreen display in response to the aircraft location being within the geofenced area without an indication of clearance to enter the geofenced area. The indication may be part of the electronic flight strip associated with the offending aircraft.
