There is considerable effort being put into the development of concepts for UAS cooperative avoidance provision in a UTM environment, building on strategic planning and usually supported by DAA to provide collision-avoidance. Whilst this is in line with ICAO’s Conflict Management concept, given the advancement in miniaturized technologies, do we actually need a traditional separation layer, or could UAS be allowed to avoid themselves? Attendees will learn about state-of-the-art technologies and concepts that could challenge the accepted wisdom for separating large numbers of drones. Who should determine the separation standards that need to be defined in a UTM environment? Where will this discussion take place.
