Aircraft identification used by Germany and Austro-Hungary in 1918.
Wing cross
10 Apr 1918 – 15 May 1918

Idflieg established dimensions for the Balkenkreuz. Sizes were to be 400, 600 and 1000 mm. The arms were to have a length-to-width ratio of 1:4. Wing and fuselage crosses had a white border of 150mm. Photographs show that a significantly thinner border was still used on rudders, although it was also common for them to be painted entirely white and carry a plain black cross.
