Autonomous Aircraft Separation via Centroid Vectoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air traffic control systems rely heavily on human intervention to maintain safe separation between aircraft in crowded airspace, which can lead to increased pilot workload and response time in emergency situations, and may not effectively manage fast-changing conditions.
Innovation Solution
A system and method for autonomously determining and directing aircraft to maintain safe separation using a reference formation airspace and centroid vectoring, allowing aircraft to independently adjust their trajectories without central guidance or communication with other pilots or air traffic controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If GPS-based ADS-B systems are used to enable tighter aircraft stacking, then more aircraft can be managed in crowded airspace, but human response time is reduced and risks increase in emergencies
Solution Approach 1:
The system enables aircraft to autonomously determine their own target trajectories and make flight adjustments to maintain separation without requiring human intervention. Each aircraft independently processes position data from GPS/ADS-B, calculates its own recovery actions, and executes maneuvers autonomously, eliminating the time delay associated with human response while maintaining high aircraft management capacity
Solution Approach 2:
The system pre-establishes a reference formation airspace (rectangular prism) around each aircraft based on minimum separation standards before any conflict occurs. This pre-configured spatial framework allows aircraft to quickly determine their target trajectory without real-time human calculation, enabling rapid autonomous response while maintaining optimized spacing for high productivity
2Reliability
If air traffic controllers provide real-time instructions to maintain separation, then safe separation is ensured, but pilot workload increases and response time is extended
Solution Approach 1:
The system transfers the separation management function from human controllers and pilots to an automated onboard system. The aircraft autonomously monitors its position within the reference formation airspace, determines when separation is compromised, calculates the target trajectory to restore separation, and executes the maneuver without human intervention, thereby ensuring safety while eliminating additional workload
Solution Approach 2:
The system continuously receives real-time position data from GPS/ADS-B, compares the aircraft's actual position against the pre-established reference formation airspace boundaries, and automatically generates corrective target trajectories when penetration is detected. This closed-loop feedback mechanism ensures separation safety through automated monitoring and correction without requiring continuous human attention
3Use of energy by moving object
If aircraft are pushed off tightly planned tracks for fuel savings, then fuel efficiency improves, but separation maintenance becomes more difficult and response time decreases
Solution Approach 1:
The reference formation airspace is not a fixed structure but dynamically adjusts to each aircraft's current position and flight path. As aircraft deviate from planned tracks for fuel efficiency, the rectangular prism reference formation moves with the aircraft, automatically recalculating the target trajectory to maintain separation from neighboring aircraft. This dynamic adaptation allows fuel-efficient routing while managing separation complexity through automated real-time adjustments

AI summary
An autonomous airspace separation system monitors flight separation for compliance with a separation standard. A reference formation airspace is established based on minimum longitudinal, lateral and vertical parameters. When penetration of the reference formation airspace is detected, a penetration airspace is established based on a deformation of the reference formation airspace caused by the penetrating aircraft. A centroid of the penetration airspace is determine and a target separation to the centroid is supplied to the aircraft to reestablish safe separation.
