Aircraft Conflict-Zone Mapping for Trajectory-Based Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aircraft collision avoidance systems fail to effectively predict and visualize potential conflicts between aircraft, leading to a loss of separation and increased risk of collisions.
Innovation Solution
An aircraft avoidance system that determines predicted trajectories of multiple aircraft, identifies conflict zones, and renders these zones on a display to alert pilots, along with recommended maneuvers to regain separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air traffic controllers manually monitor and enforce traffic separation rules, then separation management is maintained, but system complexity and workload increase
Solution Approach 1:
The aircraft avoidance system performs self-monitoring and self-alerting functions. Each aircraft independently calculates its own predicted trajectory, detects potential conflicts with other aircraft, and generates alerts for the pilot without requiring continuous manual monitoring by air traffic controllers. This transfers the separation management burden from the controller to the aircraft system itself.
Solution Approach 2:
The system continuously monitors the actual positions and predicted trajectories of aircraft, compares them against separation standards, and provides real-time feedback to pilots through alerts when conflicts are detected. This closed-loop feedback mechanism enables dynamic adjustment of flight paths to maintain separation without requiring constant manual intervention.
2Loss of information
If predicted trajectories and conflict zones are visualized on display, then pilot awareness of conflicts is improved, but display complexity increases
Solution Approach 1:
The display uses color-coded representations to indicate the status of aircraft and conflict zones. For example, aircraft may be displayed in different colors based on their separation status from other aircraft, and conflict zones may be highlighted in distinct colors or patterns. This color-coding system conveys complex separation information intuitively without requiring complex graphical representations.
Solution Approach 2:
The display interface segments information about multiple aircraft into individual, manageable elements. Each aircraft is represented as a separate graphical object with its own trajectory and separation status, allowing pilots to process information about individual aircraft relationships rather than dealing with a complex overall situation. Conflict zones are segmented and highlighted separately from individual aircraft representations.
3Measurement precision
If real-time trajectory prediction is performed, then conflict detection accuracy is improved, but computational requirements increase
Solution Approach 1:
The system performs trajectory predictions in advance based on current aircraft positions, velocities, and flight plans, rather than continuously recalculating in real-time. By preparing predicted trajectories ahead of time and updating them at discrete intervals, the system achieves accurate conflict detection while reducing peak computational demands on the aircraft's processing systems.

AI summary
An aircraft includes a display and an avoidance system. The avoidance system is configured to determine a first predicted trajectory of the aircraft, determine a second predicted trajectory of an additional aircraft, and determine a conflict zone volume based on an intersection between the first predicted trajectory and the second predicted trajectory. The conflict zone volume indicates a predicted volume of airspace in which the aircraft and the additional aircraft experience a loss of separation. The avoidance system is configured to render a conflict zone on the display based on the conflict zone volume. The rendered conflict zone graphically represents the conflict zone volume on the display.
