Workload of a collision avoidance system for remotely piloted aircraft

Active air traffic controllers and remotely piloted aircraft pilots were studied in a real time simulation providing results on actual and desired behaviour of the studied concept of a mid-air collision avoidance system in an air traffic control environment. The workload for the studied system seems to be acceptable at this state, and no major concerns regarding workload were found during the simulations. However, areas where the studied concept may be improved were identified concerning for instance suggested manoeuvre. A general conclusion from the simulations was that it is important that the D&A-system is correctly designed in regard to sensitivity.
