The term 'Plane Feature' can refer to two features of an airplane: the WING and the CABIN. The WING is the part of the plane that provides lift and is typically composed of a metal frame covered in fabric or composite materials. The CABIN is the enclosed space inside the plane where passengers and crew are seated. It is usually divided into sections, such as first class, business class, and economy class. Both the WING and the CABIN are essential components of an airplane and are necessary for it to fly.
