The SESAR 2020 project PJ05 aims to bring the concept of remotely controlling multiple airports to the next maturity level. In November 2017, Frequentis AG, HungaroControl, DLR, and Selex ES GmbH (Leonardo LTP) conducted a first successful validation campaign on “Remote Tower for Multiple airports” in Braunschweig. Multiple remote tower operations clearly show that it is possible for a single air traffic controller to safely provide air traffic control services remotely to more than one airport. At the DLR Air Traffic Validation Center in Braunschweig, a single remote tower controller managed three airports simultaneously.
