Unmanned aircraft systems must demonstrate a capability to sense and avoid air traffic as
part of a layered conflict management system to enable safe operations in the National …

RIGOROUS analysis of a collision avoidance system is required before deployment in the
airspace due to the potentially catastrophic consequences of error in their operation. Civil …

Abstract The Traffic Alert and Collision Avoidance System (TCAS) is a world-wide accepted
last-resort means of reducing the probability and frequency of mid-air collisions between …

The aircraft collision avoidance problem can be formulated using a decision-theoretic
planning framework where the optimal behavior requires balancing the competing …

Several well-known international cooperation programs in the research field of air traffic
management, eg, SESAR and NextGen, aim to overcome the deficiencies of airspace …

EXECUTIVE SUMMARY The Traffic Alert and Collision Avoidance System (TCAS) is a
widely-deployed safety system for reducing the risk of mid-air collision between aircraft …

The integration of new airspace entrants into terminal operations requires design and
evaluation of Detect and Avoid systems that prevent loss of well clear from and collision with …

Small Unmanned Aircraft Systems (sUAS) offer many potential benefits to society but also
pose a dangerous mid-air collision hazard. Safely integrating into shared airspace will …
