Researchers from the German Aerospace Center (DLR) have successfully conducted the first flight tests in a newly erected model city. The tests are part of DLR’s research project HorizonUAM and took place at the National Experimental Test Center for Unmanned Aircraft Systems in Cochstedt, Germany, in October and November 2022. The overall goal of HorizonUAM is the investigation of opportunities and risks of urban air mobility (UAM). Special focus is placed on air taxis that could transport passengers through urban airspaces, either piloted, remotely piloted or potentially fully autonomously in the future.
