What are wings?

Explanation:
Wings are airfoils attached to each side of the fuselage and are the main lifting surfaces. Their curved upper surface and relatively flatter lower surface, along with the angle at which they meet the air, create a pressure difference—lower pressure on top and higher pressure beneath—that generates lift to support the airplane’s weight. This lift is the primary reason the aircraft can fly. Other components like the fuselage and tailplane, stabilizers, or engine nacelles don’t provide the main lift; they influence stability, control, and propulsion, but the wings do the bulk of the lifting.
