About the Flight Design CT

The Flight Design CT is a German-designed light-sport aircraft that became one of the most successful LSA models worldwide following the category's introduction in 2004. Built by Flight Design General Aviation in Germany and later Ukraine, the CT family includes variants like the CTSW (side-by-side, wing tanks) and CTLS (long-span wing), all conforming to the FAA's 1,320-pound maximum takeoff weight limit for special light-sport aircraft. Its high-wing configuration, composite construction, and efficient Rotax 912-series engine deliver cruise speeds around 115 knots while maintaining the docile handling characteristics required for sport pilot certification.

The CT's success stems from its blend of modern avionics compatibility, roomy side-by-side seating, and operating economics that appeal to flight schools and private owners alike. With a stall speed below 40 knots and a never-exceed speed of 138 knots, the CT occupies the sweet spot between ultralight simplicity and cross-country capability, making it a popular choice for pilots seeking an accessible entry into modern recreational flying. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
