Aircraft configurations Wing types. Aircraft can also be categorized by their configurations. One measure is the number of wings, and the styles include monoplanes, with a single wing (that is, on either side of the fuselage); biplanes, with two wings, one atop the other; and even, though rarely, triplanes and quadplanes.
Different aircraft require different building materials. Aircraft can be constructed from wood, fabric, many types of metal, or even composite materials (e.g. carbon-fiber, fiberglass). Early aircraft such as the Wright Flyer were built with wood and fabric. The frame of the Wright Flyer was made from spruce and ash and many surfaces were covered with muslin, a fabric.
