An ARV Super2 with a shoulder-wing.
Shoulder wing designs include a wide range of aircraft from pre-World War II airliners, World War II bombers and strike aircraft, through Cold War fighters, civil and military transports to light aircraft and gliders.
There seems to be a difference of professional opinion over this sub-category. For instance, Flight describes the Short SC.7 Skyvan, an apparent high-winged aircraft, as "shoulder-winged". Arguably, the shoulder-wing terminology is of useful significance only to small aircraft, such as the Saab Safari, Bölkow Bö 208 Junior and ARV Super2.
Shoulder wing on light aircraft
The shoulder wing has a particular advantage for smaller aircraft with a canopied cockpit, in that it gives the pilot unrestricted forward visibility, especially prior to and during turns. Optimally, the shoulder wing should be positioned at the level of the pilot's eyes, to minimise any obstruction to visibility from the wing.
On a light aircraft, a shoulder-wing may need to be swept forward to maintain correct center of gravity. Shoulder wings and high-wings share two characteristics, namely: they support a pendulous fuselage which requires no wing dihedral for stability; and, by comparison with a low-winged aircraft, the limited ground effect reduces float on landing.
