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 …

Finding the most likely path to a set of failure states is important to the analysis of safety-
critical systems that operate over a sequence of time steps, such as aircraft collision …

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

Unmanned aircraft systems (UAS) will be required to equip with a detect-and-avoid (DAA)
system in order to satisfy the federal aviation regulations to remain well clear of other aircraft …

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

Airspace encounter models, which provide realistic close encounter situations
representative of the airspace, are a critical component in the safety assessment of sense …

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 …

TCAS II is a rule-based airborne collision avoidance system (ACAS) that is used in current
commercial air transport operations, and ACAS Xa is a new optimization-based system …

In the United States, general aviation piston-driven aircraft are now the largest source of
lead emitted to the atmosphere. Elevated lead concentrations impair children's IQ and can …

This presented the development and simulation of optimized collision avoidance logic to
operate on-board general aviation aircraft. Framing the collision avoidance problem as a …
