Cessna 180

The Cessna 180 Skywagon is a four- or six-seat, fixed conventional gear general aviation airplane which was produced between 1953 and 1981. Though the design is no longer in production, many of these aircraft are still in use as personal aircraft and in utility roles such as bush flying.Christy, Joe ''The Complete Guide to the Single-Engine Cessnas'' 3rd ed, TAB Books, Blue Ridge Summit PA USA, 1979, pp 29–39

Development

Cessna introduced the heavier and more powerful 180 as a complement to the Cessna 170. It eventually came to be known as the Skywagon, with the name appearing in promotional material by 1973.

The prototype Cessna 180, N41697, first flew on May 26, 1952. Cessna engineering test pilot William D. Thompson was at the controls.

In all its versions, 6,193 Cessna 180s were manufactured. In 1956, a tricycle gear version of this design was introduced as the Cessna 182, which came to bear the name Skylane. Additionally, in 1960, Cessna introduced a heavier, more powerful sibling to the 180, the conventional gear Cessna 185. For a time, all three versions of the design were in production.

Design

The airframe of the 180 is all-metal, constructed of aluminum alloy. The fuselage is a semi-monocoque structure, with exterior skin sheets riveted to formers and longerons. The strut-braced wings, likewise, are constructed of exterior skin sheets riveted to spars and ribs. The landing gear of the 180 is in a conventional arrangement, with main gear legs made of spring steel, and a steerable tailwheel mounted on a hollow tapered steel tube.

Cessna 180s produced between 1953 and 1963 have two side windows, while 1964 to 1981 models feature three side windows, as they use the same fuselage as the Cessna 185. 180s can be equipped with floats and skis.

Operational history

Record flight

The Cessna 180 gained recognition as the aircraft chosen by Geraldine Mock, the first woman pilot to successfully fly around the world. The flight was made in 1964 in her 1953 model, the '' Spirit of Columbus'' (N1538C), as chronicled in her 1970 book ''Three-Eight Charlie''.Mock, Jerrie: ''Three-Eight Charlie'', First Edition, 1970. The Cessna factory obtained the aircraft and kept it at the Pawnee (Wichita, Kansas) manufacturing plant after the epic flight, suspended from the ceiling over one of the manufacturing lines. It is currently on display at the National Air and Space Museum.

Variants

''Cessna has historically used model years similar to U.S. auto manufacturers, with sales of new models typically starting a few months prior to the actual calendar year.''
