Airplanes have been designed with
many numbers of wings. Each wing is
actually called a plane. Monoplanes
have one wing plane. Biplanes have
two wing planes stacked vertically;
triplanes have three; quadruplanes
have four; and airplanes have even
been designed with as many as
200 planes! Tandem winged planes
have two wing planes, but they are
positioned horizontally, not vertically.
The benefit of adding more wing
planes is that each plane adds to the
total lift. However, each plane also
adds to the weight and drag, and each
plane interferes with the other planes.
As planes got faster and faster, the
monoplane design was favored.

DIHEDRAL & ANHEDRAL
The angle of the wing relative to the horizontal is called the dihedral (if it’s above
the horizontal) or the anhedral (if it’s below the horizontal). By angling the wings in
this way, the airplane’s stability against rolling sideways improves tremendously.
