Number 30 in 100 in 100, The Cessna 210 Centurion 🛩️
Conceptualization
The Cessna 210 Centurion was developed in response to the aviation market trends of the late 1950s and early 1960s, which demanded faster, more versatile, and higher-performance single-engine aircraft. Pilots and aircraft owners sought planes combining speed, range, and the ability to operate from shorter airstrips, catering to private operators and flight schools. Cessna aimed to address these needs by producing an aircraft with retractable landing gear, a powerful engine, and a spacious cabin. This approach leveraged technological advancements to meet both current and anticipated future market demands, establishing the 210 Centurion as a leader in its class.
Original Design
The original design of the Cessna 210 Centurion, which first flew in January 1957 and entered production in 1960, featured several standout elements. The retractable landing gear reduced drag, enhancing aerodynamic efficiency and speed. A powerful 260-horsepower Continental IO-470 engine provided impressive performance. The cantilever wing design, which lacked supporting struts, further improved aerodynamics. The aircraft's spacious cabin could seat up to six people. Advanced avionics for its time improved navigation and safety, while the all-metal construction ensured durability, appealing to both personal owners and flight schools.

Designer/Team
The design and development of the Cessna 210 Centurion was led by Cessna Aircraft Company's engineering department. Specific individuals of the team are not prominently known, but the collective expertise of Cessna's design team was instrumental. The team had experience in earlier successful models such as the Cessna 170, 180, and 182. Their expertise enabled the integration of advanced features like retractable landing gear and cantilever wings. The design team continued to innovate post-210, contributing to later models like the Cessna 206 and 310, further cementing their legacy in aviation design.
Production Run
The Cessna 210 Centurion first flew in January 1957 and entered production in 1960, continuing until 1986. During this time, approximately 9,240 units were manufactured. The early production years focused on the original design, with significant changes introduced in 1966 with the 210G model and 1970 with the 210K model. The 210G featured a lengthened fuselage and increased fuel capacity, while the 210K offered an enlarged cabin and a more powerful engine. The introduction of the pressurized P210N in 1979 allowed higher altitude flying. Production volumes varied with market demand, peaking in the late 1960s and early 1970s, and declining by the mid-1980s.
