The concept of Free-Flight, introduced in the 90s, opened a debate on the efficiency of letting aircraft deal with conflicts without any centralized control. Many models have been proposed for autonomous aircraft solvers but their efficiency is not well-known. In this paper, we experiment powerful algorithm derived from robotics which is able to deal with thousands of robots in very small spaces, and show how its performance plummets when speeds are constrained. We also compare this autonomous… 
Dynamic collision avoidance using local cooperative airplanes decisions
TLDR
This work proposes an autonomous and generic multi-agent system to address the collision avoidance management problem using a decentralized distributed approach and validates the system using state-of-the-art benchmarks.
Cooperative multi-agent model for collision avoidance applied to air traffic management
TLDR
This work proposes an autonomous and generic multi-agent system to address this complex problem, where mobile entities are agents, that use a finite set of discrete speed vector modifications to follow their trajectories while avoiding separation losses.
Directional optimal reciprocal collision avoidance
TLDR
The Optimal Reciprocal Collision Avoidance (ORCA) algorithm is modified to make it work for autonomous and decentralized collision avoidance for civil aircraft and direction selectivity of the algorithm enables the process of collision avoidance to comply with the unified rules.
A decentralized method for collision detection and avoidance applied to civil aircraft
TLDR
A decentralized method is proposed so that each aircraft can generate the collision-free Reference Business Trajectory (RBT) autonomously, and resolve potential conflicts while conforming to the unified rules.

In this article, we test a horizontal detect and avoid algorithm for UAVs flying in the lower airspace (under FL180). We use recorded commercial traffic trajectories and randomly build 3000 conflicts
Evaluation of an Automatic Separation Algorithm for Unmanned Aircraft Systems
TLDR
An algorithm for automatic cooperative separation among remotely piloted aircraft system and other air traffic is presented, based on the concept of modified velocity obstacles, which will make use of the existing infrastructure as well as vehicle communications developed in this project.
An Airborne Approach for Conflict Detection and Resolution Applied to Civil Aviation Aircraft based on ORCA
TLDR

Many of the nation's airspace users desire more freedom in selecting and modifying their routes. This desire has been expressed in the free flight concept, which has gained increased attention in the

Conflict resolution problems for air traffic management systems solved with mixed integer programming
TLDR
This paper proposes two different formulations of the multiaircraft conflict avoidance problem as a mixed-integer linear program: in the first case only velocity changes are admissible maneuvers, in the second one only heading angle changes are allowed.

TLDR
This work extends the model of a simple car to a simple-airplane, which has constraints on speed and steering angle and includes a configuration variable for the altitude, and uses a locally optimal reciprocal collision avoidance scheme that computes the trajectory without any collisions or oscillations for each airplane independently.
