Shoulder wing

Shoulder wing aircraft with a lifting means a surface which is flush with the upper edge of the hull. Typical aircraft are the Cessna 150/152 and the Glider Schleicher K 8

An advantage of the shoulder wing design is the fact that the wing rail is not guided by the fuselage; another good ground visibility from the cockpit. One drawback (at least for large, multi-engine airplanes ) is a more elaborate design of the chassis.

For cargo aircraft for bulky goods, the monoplane design is preferred because it is in the range of the wings restricts the cargo hold less. In turboprop aircraft it possible to arrange the engines higher, so that the propellers have sufficient ground clearance without an expensive high chassis is required. The low chassis allows the use of on-board stairs for boarding or for cargo aircraft a rear ramp for loading on passenger aircraft.
