Arkansas CX-3
The Command-Aire 3C3 and similar 4C3 and 5C3 are United States, American three-seat open cockpit utility, training and touring biplanes developed by Command-Aire in the late 1920s and early 1930s. Design and development The Command-Aire did not at first appear to offer much of an advancement over the vast multitude of three seat biplanes built around the ubiquitous Curtiss OX-5 engine to similar designs, with similar dimensions and construction methods, many of which were already in production. Indeed, the OX-5 era was coming to an end. The vast quantities of war-surplus engines, which had swamped the market in the immediate post-war period, were running low. Only by the smaller details can it be distinguished from its brethren. The basic design was by Morton Cronk, and although it had excellent high altitude capabilities, it was slow. This setback nearly foundered the company before its first aircraft entered production. The design's proportions were good, but Cronk's departur ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...
