The Cessna 320 Skyknight occupies a unique slot in the legacy Cessna twin lineup, bridging the gap between the non-pressurized 310 and the larger 340. Built from 1961–1969, the 320 introduced factory turbocharging, cabin pressurization (on later models), and wing-mounted auxiliary tip tanks that boosted both range and useful load. Its blend of speed, altitude capability, and familiar Cessna handling made it a strong choice for owner-pilots needing a dependable, long-legged twin for business or personal travel.
With cruise speeds around 200–215 KTAS, ranges stretching past 1,000 NM (with long-range fuel), and a service ceiling surpassing 20,000 feet, the 320 remains a significant step up from the 310 in capability. Owners appreciate its direct, well-damped control feel, predictable systems, and the same mechanical logic found across Cessna’s classic twins.
The first Skyknight set the foundation for the line, introducing turbocharged Continental TSIO-470 engines and auxiliary wingtip fuel for increased endurance. While lacking pressurization, it offered strong performance and a comfortable cabin, making it a compelling upgrade for owners seeking higher cruise speeds and improved high-altitude capability without moving into a full cabin-class twin.
The 320A refined the original with improved systems integration, revised engine installations, and tweaks to the cabin and fuel handling that made daily operation smoother. Handling remained predictable and balanced, and the aircraft benefited from early aerodynamic clean-ups that slightly sharpened cruise performance and climb rates while maintaining straightforward ownership and maintenance characteristics.
The 320B introduced structural enhancements, strengthened landing gear components, and additional fuel options that extended practicality for longer missions. Owners appreciated its stable feel in IMC and its ability to carry meaningful payload at near-200-knot cruise speeds. This variant cemented the 320’s reputation as a serious cross-country platform with reliable turbocharged power.
The 320C marked the biggest leap forward, adding true cabin pressurization, reinforcing the airframe, and incorporating system upgrades needed for routine operations in the high teens and low flight levels. With its combination of speed, altitude reach, and enhanced comfort, the 320C delivered a distinctly executive feel and broadened the aircraft’s mission profile for owners needing consistent all-weather, all-terrain capability.
The 320D benefited from aerodynamic smoothing, updated interior appointments, and incremental system improvements that increased efficiency and reduced workload. Turbocharging performance was refined to provide more consistent power delivery across altitude bands, and the pressurized cabin was further optimized for comfort, making this model a polished balance of utility and refinement ideal for dedicated mission flying.
The final Skyknight variant offered the most refined combination of power, systems, and comfort, integrating small but meaningful tweaks throughout the aircraft. Operators praise its predictable high-altitude behavior, steady cruise speeds, and durable systems that held up well under regular use. As the culmination of the line, the 320E represents the most capable and well-rounded execution of Cessna’s pressurized light twin concept.
Upgraded Systems
Incremental improvements to electrical components, panel layout, and subsystem reliability make the 320E easier to operate and maintain.
Refined TSIO-470 Powerplants
Improved turbocharger configuration and cooling airflow give more predictable power delivery and better performance across altitude bands.
Aerodynamically Cleaned Airframe
Subtle refinements to fairings, cowl contours, and control surface rigging result in more efficient cruise and reduced drag at typical mission speeds.
Enhanced Cabin Comfort
Updated interior materials and improved soundproofing give the 320E a more refined passenger environment during long cross-country flights.
Expanded Fuel Capacity
The signature wingtip tanks offer extended range and help offload wing stresses while preserving strong useful load for passengers and bags.
Fully Integrated Pressurization
Mature pressurization package provides consistent cabin differentials and smoother high-altitude operations compared to earlier variants.
Higher Cruise Efficiency
Aerodynamic clean-ups translate into better true airspeeds for the same fuel burn, improving mission economics.
Reliable Turbocharged Performance
Strong engine response across a wide altitude window provides confident climb rates and consistent power for weather and terrain management.
Comfortable, High Altitude Travel
A stable pressurization system keeps the cabin environment predictable and reduces fatigue on longer trips.
Extended Mission Range
Large tip-tank capacity supports longer nonstop legs, reducing fuel stops and expanding operational flexibility.
Reduced Pilot Workload
System refinements and cleaner panel organization make the aircraft simpler to manage during both IFR and routine operations.
Refined Cabin
Improved acoustic damping enhances passenger comfort and gives the aircraft a more polished, executive feel.
