A framework to handle threats for UAS operating in the U-space

This paper presents a framework to handle threats for UAS operating in the U-space. During UAS operations, unexpected events or threats can happen and put the UAS in danger. In order to handle those situations, we propose a module for threats management that incorporates autonomous decision-making capabilities and is integrated with the U-space. First, we survey related works and compile a classification of event classes as well as possible contingency or emergency procedures. Then, we devise an approach to integrate our decision-making procedure within the U-space framework. This approach selects the proposed mitigation actions depending on the operational state of the UAS involved. Our framework takes a step forward in the integration of autonomous systems in the U-space, as there is no current solution for emergency management without the intervention of UAS operators.
