EXECUTIVE SUMMARY The Traffic Alert and Collision Avoidance System (TCAS), currently
mandated on all large transport aircraft, has been shown to significantly reduce the risk of …

Drones have been greatly developed to facilitate the progress of various industries. The safe
operation of drones in the urban airspace is critical to ensure a reliable and high-efficient …

Demand for small unmanned aircraft systems (sUAS) continues to increase in diversity and
volume, however applications are currently limited by regulatory requirements for visual …

This paper presents a feasible 3D collision avoidance approach for fixed-wing unmanned
aerial vehicles (UAVs). The proposed strategy aims to achieve the desired relative bearing …

Urban Air Mobility (UAM) will result in numerous aircraft which will need to respond to a
dynamically changing airspace to safely reach their destinations. We use a highly efficient …

An important consideration in the development of aircraft collision avoidance systems is how
to account for state uncertainty due to sensor limitations and noise. However, many collision …

This paper presents an extension to the ACAS X collision avoidance algorithm to multirotor
aircraft capable of using speed changes to avoid close encounters with neighboring aircraft …

All large transport aircraft are required to be equipped with a collision avoidance system that
instructs pilots how to maneuver to avoid collision with other aircraft. The uncertainty in the …

We show how to combine Bayes nets and game theory to predict the behavior of hybrid
systems involving both humans and automated components. We call this novel framework …

Safely integrating unmanned aerial vehicles into civil airspace is contingent upon
development of a trustworthy collision avoidance system. This paper proposes an approach …
