Aircraft Conflict Resolution Using Priority-Based Deflection Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of aircraft in the air leads to flight conflicts due to overlapping routes and speeds, resulting in reduced flight safety when the minimum distance between aircrafts is less than a preset distance.
Innovation Solution
A flight conflict resolution method and apparatus based on ultimatum game theory, which determines priority angles for deflection to maintain a safe distance between aircrafts by calculating negotiation angles and deflection angles using specific formulas, ensuring that the minimum distance between aircrafts is greater than or equal to a preset distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of aircraft in the airspace increases, then the air traffic capacity and transportation efficiency are improved, but the flight safety deteriorates due to increased flight conflicts and reduced minimum distance between aircrafts
Solution Approach 1:
The system performs preliminary detection of flight conflicts by calculating the minimum distance between aircrafts within a preset time period before the conflict actually occurs. By identifying potential conflicts in advance and applying deflection angles proactively, the system prevents safety issues while allowing increased air traffic capacity.
Solution Approach 2:
The conflict resolution system acts as an intermediary between multiple aircraft by introducing a third angle that mediates the distance relationship between conflicting aircrafts. This intermediary mechanism coordinates deflection angles to maintain safe distances while managing increased air traffic flow.
2Ease of operation
If aircrafts maintain fixed routes and speeds, then the flight operation simplicity and energy efficiency are improved, but the flight safety deteriorates when route intersections cause minimum distance to be less than preset distance
Solution Approach 1:
Instead of requiring continuous route changes for all aircraft, the system applies deflection angles only to specific aircraft involved in detected conflicts. This partial action maintains simplicity for non-conflicting aircraft while resolving safety issues locally where needed.
Solution Approach 2:
The system enables aircraft to self-adjust their routes by calculating and applying appropriate deflection angles based on detected conflicts. Each aircraft independently determines its own route modification needs based on the conflict resolution algorithm, reducing the complexity of centralized control.
3Reliability
If deflection angles are applied to resolve flight conflicts, then the flight safety is improved by maintaining minimum distance greater than or equal to preset distance, but the flight route deviation and operation complexity increase
Solution Approach 1:
The system resolves conflicts by changing the route parameters (deflection angles) of aircraft in a controlled manner. By adjusting angles within preset limits and only when conflicts are detected, the system maintains safety while minimizing unnecessary route deviations and operational complexity.
