AEG B-Types

   After some unspecified problems were overcome the air service ordered six B-type (unarmed, two-seat biplanes) of the Z6 type for training and operations that were delivered in early 1914.

AEG B.I

   The AEG Z6 gave satisfactory service and the air service ordered 20 improved aircraft (Z6a) in April 1914. These were powered by a variety of 100-120 hp NAG, Mercedes, or Benz six-cylinder engines. A small number of these aircraft served at the front between August 1914 and December 1915, their steel-tube structures proving their reliability and durability. When Idflieg published the new aircraft designations in August 1915 the AEG Z6a biplanes were retroactively designated AEG B.I even though they were no longer in production.

6. The New A.E.G. Biplane
   differs from the machine described above in that it has no back-swept wing tips. The main planes are straight, as seen in plan, but are set at a very pronounced dihedral angle. For purposes of transport they can be folded flat along the sides of the fuselage. The chassis has three wheels, of which the front one, protecting the propeller, is sprung by means of a coil spring on a steel tube sloping backwards to the nose of the fuselage.
