Template:Short description Template:Infobox aircraft

The Hansa-Brandenburg B.I was an unarmed military trainer and reconnaissance biplane of World War I, flown by the Austro-Hungarian Air Service. Early models were known internally to the Hansa-Brandenburg firm as the type D, while later models with a more powerful engine were designated FD. This aircraft was one of the earliest designs of Ernst Heinkel, who was working for Hansa-Brandenburg at the time. It was an entirely conventional two-bay biplane with staggered wings of unequal span. The pilot and observer sat in tandem in a long open cockpit.

The aircraft was produced under license by Aero, both during the war and afterwards (when it became known as the Aero Ae 01), and also by Letov, as the Š10.[1] Experience gained with this design would provide Aero with the basis for a number of derivative civil and military designs throughout the 1920s.

The design formed the basis for the C.I and C.II armed reconnaissance types.

Development and design

In April–May 1914, the aircraft designer Ernst Heinkel joined the newly established Brandenburgische Flugzeugwerke after leaving Albatros Flugzeugwerke, and shortly afterwards, Brandenburgische Flugzeugwerke merged with Hansa-Flugzeugwerke to become Hansa-Brandenburg.Script error: No such module "Footnotes".Script error: No such module "Check for unknown parameters". Heinkel's first design for Hansa-Brandenburg was the Type D, a single-engined reconnaissance aircraft. It was a two-bay biplane with wood and fabric wings and tail surfaces, and a fuselage of steel tube structure covered with plywood. It was powered by a Script error: No such module "convert".
