The Avia BH-6 was a prototype fighter aircraft built in Czechoslovakia in 1923. It was a single-bay biplane of unusual configuration developed in tandem with the BH-7 which shared its fuselage and tail design. The BH-6 had wings of unequal span but unusually the top wing was the shorter of the two; and while it was braced to the bottom wing with a single I-strut on either side these sloped inwards from bottom to top.
