High Quality Content by WIKIPEDIA articles! The LFG Roland D.III was a fighter aircraft produced in Germany during World War I. It was a further development of the D.I fighter, itself derived from the C.II reconnaissance aircraft. These machines had a fuselage that completely filled the interplane gap, a design feature intended to improve aerodynamics. However, it also resulted in limiting the pilot`s field of vision in the down and forward direction, leading to complaints. LFG attempted to remedy this in the D.III design by introducing a gap between the upper fuselage and the upper wing, braced by cabane struts. The size of the tailplane was also increased.
