What is the Cessna TTx, and how does it compare?

The Cessna TTx is a four-seat, all-composite, turbocharged piston single built for fast cross-country flying. Developed from the Columbia 400 and Cessna Corvalis TT, it combines a 310 hp Continental engine, fixed landing gear and Garmin G2000 avionics, with a published maximum cruise speed of about 235 KTAS.

Within our Aviation & Real-World Flying coverage, the TTx sits at the fast end of certified piston singles rather than among Cessna’s familiar high-wing trainers. Our overview of how the main Cessna families differ provides the wider context.

What makes the Cessna TTx different?

The TTx achieves near-retractable-gear performance while retaining fixed tricycle landing gear. Its clean composite airframe reduces drag, while the turbocharged and intercooled Continental TSIO-550-C maintains power as altitude increases.

• Construction: a low-wing composite airframe with four seats and two upward-opening cabin doors.
• Engine: a 310 hp, six-cylinder turbocharged piston engine driving a constant-speed propeller.
• Controls: conventional mechanically connected side-sticks, not fly-by-wire controls.
• Avionics: an integrated Garmin G2000 flight deck with touchscreen controllers.
• Landing gear: fixed gear, avoiding retraction-system maintenance and gear-up landings.
• Cabin: unpressurised, so high-altitude operation requires supplemental oxygen and appropriate operating clearances.
• Safety equipment: no factory whole-aircraft parachute, a major distinction from the Cirrus SR22T.

The TTx meets the US regulatory definition of a high-performance aeroplane because it has more than 200 hp. Despite its speed, its fixed gear means it is not a complex aeroplane under the usual US definition. Licensing terminology and endorsement rules differ between countries.

For the distinction between turbocharged piston power and other propulsion systems, see our explanation of Cessna piston, turboprop and jet engines.

How does the Cessna TTx compare with rival piston singles?

The TTx is faster than most fixed-gear piston singles, but each rival trades speed for a parachute, pressurisation, extra seating or different operating economics.

These are representative manufacturer maximums and common seating configurations, not guaranteed trip-planning figures. Model year, equipment, weight, altitude, temperature and power setting all affect performance.

Cessna TTx versus Cirrus SR22T

The TTx offers higher published maximum cruise speed, while both aircraft avoid retractable-gear complexity. The SR22T counters with the Cirrus Airframe Parachute System, up to five seats in later examples and a large training and support ecosystem.

Cockpit preference also matters. The TTx uses side-sticks, while the Cirrus has side-yokes. Neither arrangement is fly-by-wire, but pilots should receive model-specific transition training rather than treating them like faster versions of a conventional trainer.

Cessna TTx versus Mooney Acclaim

The Mooney Acclaim can be slightly faster and highly efficient, helped by retractable landing gear and a narrow airframe. The TTx provides a wider-feeling cabin and removes the landing-gear system from the pilot’s workload, but carries the drag of fixed gear.

The choice is largely between the TTx’s fixed-gear simplicity and the Mooney’s aerodynamic efficiency. Maintenance access, cabin fit and the availability of type-experienced engineers can matter more than a few knots of brochure speed.

Cessna TTx versus Bonanza G36 and Piper M350

The Bonanza G36 prioritises cabin flexibility and six-seat capacity rather than turbocharged high-altitude speed. Its normally aspirated engine loses power with altitude, while its retractable gear adds another operating system.

The Piper M350 is not a direct like-for-like rival because it is a larger, six-seat pressurised aircraft. Pressurisation makes high-altitude travel much more comfortable, but brings additional systems, maintenance and training requirements.

Will a Cessna TTx really cruise at 235 knots?

About 235 KTAS is a best-case published maximum, not an everyday block speed. It depends on operating high enough for the turbocharging and true-airspeed advantage to pay off, using a high cruise-power setting under suitable atmospheric and weight conditions.

Lower-altitude economy cruise will be slower. A real journey also includes climb, descent, routing, winds and fuel stops, so comparing aircraft solely by maximum cruise speed is a common mistake. Payload with full fuel and the chosen reserve policy often decide which aircraft completes a trip fastest.

What is the Cessna TTx like to operate?

The fixed gear simplifies one part of the workload, but the TTx is still a powerful, slippery aeroplane that demands disciplined speed and engine management.

• Approach speed: arriving only a few knots fast can produce a long float and use much more runway. Speed brakes, where fitted, help manage descents but do not correct a poorly planned approach.
• Taxi steering: the free-castoring nosewheel relies on rudder and differential braking at low speed. Excessive brake use causes unnecessary wear.
• Engine management: pilots must use the aircraft’s approved procedures and monitor cylinder-head and turbocharger-related temperatures. Maximum speed also comes with substantial fuel flow.
• Payload: four seats do not automatically mean four adults, full fuel and baggage. Actual useful load varies with equipment and individual airframe weight.
• High-altitude flight: the cabin is not pressurised. Oxygen endurance, passenger tolerance and weather can become limiting factors before the aeroplane reaches its service ceiling.
• Ice protection: equipment and approvals vary. Visible fluid panels or other anti-ice equipment do not alone prove that a particular aircraft is approved for flight into known icing.

Is the TTx the same as the Columbia 400 or Corvalis TT?

The aircraft belong to the same design family, but the names do not identify identical cockpit configurations. Cessna acquired the Columbia design, marketed versions as the Cessna 400 and Corvalis TT, then developed the TTx with its Garmin G2000 flight deck and other refinements.

Earlier Columbia and Corvalis aircraft may have Avidyne or Garmin G1000 avionics. An aircraft labelled Corvalis TT or Columbia 400 in a simulator is therefore a close predecessor, not necessarily an exact TTx reproduction. Our coverage of the Corvalis TT in X-Plane 10 shows the family’s simulator connection.

Which high-performance single should you choose?

• Choose the TTx for very high fixed-gear speed, a broad four-seat cabin and side-stick controls, provided an unpressurised cabin and lack of a parachute suit the mission.
• Choose the SR22T when the whole-aircraft parachute, later five-seat layout and wider training ecosystem outweigh the TTx’s speed advantage.
• Choose the Mooney Acclaim when maximum piston-single speed and efficiency take priority over fixed-gear simplicity and cabin width.
• Choose the Bonanza G36 for six-seat flexibility, conventional handling and lower-altitude touring rather than maximum turbocharged cruise performance.
• Choose the Piper M350 when pressurisation and six seats justify the added cost, weight and system complexity.

What should a used Cessna TTx buyer check?

Cessna ended TTx production in 2018, so condition, records and support matter more than a simple comparison of advertised specifications.

1. Review the complete maintenance history. Look for damage, composite repairs, recurring defects and evidence that required inspections were completed by people familiar with the airframe.
2. Assess the engine and turbocharging system. Engine time alone is not enough; operating history, oil analysis, compression results, borescope findings and temperature-related evidence provide better context.
3. Test the integrated avionics. Confirm that displays, touchscreen controllers, autopilot and associated equipment work correctly and remain supportable.
4. Calculate the actual payload. Use that aircraft’s current weight-and-balance data rather than a brochure useful-load figure.
5. Verify optional equipment and approvals. Check oxygen-system status, ice-protection approval, air conditioning and any modifications against the aircraft records.
6. Confirm training and insurance terms. Insurers may require initial or recurrent type-specific instruction, especially for pilots moving directly from slower trainers.
