Tandem wing

• A biplane whose wings are stacked more or less vertically, one above the other, and where a separate tailplane surface is required,
• A Delanne wing aircraft where the rearmost tandem wing is smaller than the forward wing, thereby resembling an outsize tailplane.
• A canard or "tail-first" configuration where the forward surface is much smaller and contributes primarily to control and/or stability.
