Operational history

Two test 'hops' covering a ground distance of 200–300 metres (220-330 yards) at a maximum altitude of about were made in 1914 by pilot Petre Macavei at Cotroceni airfield. Military authorities of the time refused permission to continue the tests. At a later date, pilots Mircea Zorileanu and Gheorghe Negrescu obtained permission from the Romanian Minister of War to modify the controls of the aircraft and continue the experiments, but it never flew again. In 1916, during the German occupation of Bucharest, an A Vlaicu III was seized and shipped to Germany. It was last seen in 1942 at an aviation exhibition in Berlin by Romanian military officers. However, no mention of it is made in records of the Berlin exhibition.Gheorghiu, Constantin C. (1960). Aurel Vlaicu, un precursor al aviaţiei româneşti. Bucharest: Editura Tehnică.
