Riley-Cessna Riley Super P210

Single Piston· 458 globally registered

The Cessna P210 Centurion is the pressurized variant of Cessna's high-performance single-engine retractable, produced from 1978 through 1986. It holds the distinction of being one of the few piston singles ever certified with cabin pressurization, offering a 3.4 psi differential that allows comfortable cruise at altitudes up to 20,000 feet where most unpressurized singles struggle. Powered by a turbocharged Continental TSIO-520 engine producing 310 horsepower, the P210 delivers true airspeeds around 200 knots while maintaining sea-level cabin pressure well into the flight levels, a capability that made it popular with owner-pilots flying long cross-country missions over mountainous terrain. Cessna built the P210 on the airframe of the normally aspirated 210 Centurion, itself already known for its roomy cabin and useful load, but added a pressure vessel, environmental system, and stronger landing gear to handle the higher operating weights. The result was an airplane that could carry four adults and baggage in shirt-sleeve comfort above most weather, though at the cost of added complexity and maintenance compared to its unpressurized sibling. Maximum takeoff weight reached 4,000 pounds, and the type's service ceiling of 27,000 feet remains impressive for a piston single even by modern standards. Production ended in 1986 as the general aviation market collapsed, but the P210 remains sought-after on the used market for its unique combination of single-engine economy and pressurized capability.
