In 1916, Dr Waldemar Geest designed a single-seat fighter which, built by Automobil und Aviatik AG of Leipzig-Heiterblick, utilised his patented Mowe (Seagull) type wing. The Mowe wing featured varying incidence angle and dihedral over its planform to compensate for forward and lateral gusts, and the excellent stability that it offered had been demonstrated by six Mowe monoplanes built prior to World War I. The Mowe wing concept was adapted by Dr Geest for a fighter of staggered single-bay biplane configuration powered by a 160 hp Mercedes D III six-cylinder water-cooled engine. During military trials, performed in 1917, the Geest fighter attained an altitude of 11,485 ft (3 500 m) in 17.5 min and a maximum speed of 99 mph (160 km/h), but development was discontinued and no further aircraft employed the Mowe wing.
