Which wing design is used by most commercial aircraft?
You may have noticed that most large airliner wings are designed with dihedral. The wing tips are farther off the ground than the wing root. Highly maneuverable fighter planes, on the other hand usually have the wing tips lower than the roots giving the aircraft a high roll rate. Dihedral is the upward angle of the wings (or tail surface) from a horizontal axis. Dihedral makes aircraft more laterally stable, which means they are more stable when they roll left or right.
How to design a wing of an aircraft?
Typical airplane wing consists of skin, stringers, spar(s), ribs. In a fixed-wing aircraft, the spar is often the main wing structural member. Spar is installed spanwise at right angles (or depending on wing sweep) to the fuselage. Purpose of the spar is to carry flight loads and transfer them to the fuselage. The wingbox of a fixed-wing aircraft is the primary load-carrying structure of the wing, which forms the structural centre of the wings and is also the attachment point for other wing components such as leading edge flaps, swing wings, trailing edge flaps and wing-tip devices.Typical airplane wing consists of Skin, Stringers, Spar(s), Ribs.

What is the best wing shape?
Many airplanes have been designed with linearly tapered wing shapes. They offer a good compromise between weight and structural efficiency, enhancing aerodynamic performance by reducing induced drag and improving fuel efficiency. Lambda wing, as known as Λ wing, is named for its trailing edge containing forward swept and backward swept parts while its shape is similar to the Greek letter Λ.A wing planform in which the chord of the wing changes continuously from the Center of the wing to the wing tip. In addition, this may be accompanied by a taper in the depth of the airfoil.
