Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining runway locations are inadequate, particularly in situations where aircraft state information is not readily available or up-to-date, leading to potential collisions due to lack of accurate information about occupied runways.
Innovation Solution
A system and method that utilize aircraft state information from one or more aircraft to determine the coordinates of a runway, allowing for interpolation and extrapolation to accurately locate the runway, which can be stored and shared among aircraft systems to prevent collisions.

Engineering Contradiction Analysis
1Reliability
If traditional database information is used to determine runway locations, then the system is simple to operate, but the information may be outdated or unavailable leading to potential collisions
Solution Approach 1:
The system implements feedback by continuously collecting real-time aircraft state information from multiple sources and using it to update and refine runway location determinations. This creates a closed-loop system where actual operational data feeds back into improving the accuracy of runway location information, ensuring it remains current and reliable for collision prevention.
Solution Approach 2:
The system performs self-service by automatically determining runway locations through aggregation and analysis of aircraft state information without requiring manual updates. The system autonomously processes position data, velocity vectors, and aircraft state from multiple sources to continuously maintain accurate runway location information, eliminating dependency on external database updates.
2Measurement precision
If aircraft state information from multiple aircraft is aggregated to determine runway locations, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The system applies universality by using a multi-functional processor that can perform various operations including receiving aircraft state information, determining aircraft positions, calculating velocity vectors, aggregating data from multiple sources, and determining runway locations. This single processor handles multiple functions that would otherwise require separate systems, reducing overall complexity while maintaining high measurement precision through comprehensive data aggregation.
3Reliability
If real-time aircraft state information is processed to determine runway locations, then the reliability of collision prevention improves, but the processing requirements and system complexity increase
Solution Approach 1:
The system merges multiple data streams from different aircraft and sources into a unified processing framework. By combining position data, velocity vectors, and aircraft state information from multiple sources into a single aggregation process, the system achieves reliable collision prevention through comprehensive real-time information while avoiding the complexity of multiple separate processing systems.

AI summary
In some examples described herein, a runway location is determined based on aircraft state information from at least one aircraft. For example, a processor may determine the coordinates of one or more points of a runway based on aircraft state information generated by one or more aircraft using the runway. In some examples, the processor may aggregate coordinates determined from the aircraft state information provided by a plurality of different aircraft in order to determine the location of the runway. The processor can be located onboard an aircraft providing the state information, onboard a different aircraft, or external to any aircraft.
