The Cessna 210 Centurion is a six-seat, high-performance, retractable-gear single-engine general aviation aircraft which was first flown in January 1957 and produced by Cessna until 1985.
The early Cessna 210 (210 and 210A) had 4 seats with a Continental IO-470 engine of 260 hp (190 kW). It was essentially a Cessna 182B to which was added a retractable landing gear, swept tail, and a new wing. In 1961 the fuselage and wing were completely redesigned - the fuselage was made wider and deeper, and a third side window was added. The wing planform remained the same, but the semi-Fowler flaps (slotted, rear-moving) were extended outboard, from Wing Station 100 to Wing Station 122, which allowed a lower landing speed (FAA certification regulations state that a single-engine aircraft must have a flaps-down, power-off stall speed no greater than 70 miles/hour).
The aircraft was offered in a normally aspirated version, designated the model 210, as well as the turbocharged T210 and the pressurized P210 versions. The Centurion II was an option introduced in 1970 with improved avionics, and was available in both normally aspirated and turbocharged versions (Turbo Centurion II)
