This would have made controlling the aircraft more difficult as the pilot only had limited range to shift his or her weight in the cockpit.

Besides the intent to increase lift, the upper deck also changes the flight mechanical properties in comparison to the monoplane.

The aerodynamic center is higher and therefore increases flight stability, but reduces lateral control authority.

An authentic replica of the Large Biplane made by the Otto Lilienthal Museum has been investigated by the German Aerospace Center (DLR) during flight tests in California and North Carolina.

[2] The results prove that the glider was stable in pitch and roll and can be flown safely at moderate altitudes in smooth air.
