– CTLS –

The Airplane

flight design aircraft

The CTLS is the newest EASA Type-Certified evolutionary model of the Flight Design CT line of aircraft. Longer, lower and sleeker, the CTLS was designed specifically for the Light-Sport category and offers many features to improve comfort and performance.

Flight Design has conducted extensive customer research including questionnaires at leading air shows. Based on those results and the design opportunities allowed under the ASTM Light-Sport standards, the CTLS was developed.

The Flight Design development team worked for more than 24 months on development of the CTLS and invested significantly in this evolved design.

Flight Design used industry specialists and advanced tools including full-scale wind tunnel testing in the Mercedes wind tunnel to further refine the new aerodynamic design. Next generation computer flight test systems were used to develop the flight dynamics in a first for the Light-Sport Aircraft industry.

Flight Design is committed to remain the leader in the Light-Sport Aircraft category. Employing progressive design concepts and modern safety know-how, Flight Design joins the latest engineering techniques and software to state-of-the-art materials.

The CTLS is an aircraft capable of flying non-stop from Chicago to NYC, Charlotte to Dallas, and London to Frankfurt or Munich to Rome… flights of 1800 km (1000 miles). The large comfortable cabin and excellent visibility of the CTLS makes all your flights more enjoyable and a better environment for learning how to fly.

In production since 1997, more than 2000 Flight Design CTs have been delivered to customers, worldwide. By operating the CTLS in some of the most challenging conditions on earth, Flight Design team members continue to learn and improve the aircraft. The CTLS incorporates evolutionary changes that make it a great airplane for the demands of flying clubs and flight schools as well as private owners.

A modern aircraft should have all the safety improvements available for protecting the pilot and passenger. Every CT has a time-proven rigid carbon fiber cockpit forming a safety cell plus four-point harnesses. The standard equipment airframe parachute system is an important addition to the list of safety features on the CTLS. The system is always available should you need it.

A German Airworthiness Certificate was first issued in 1997. The Special Light Sport Aircraft FAA Airworthiness Certificate was issued to a CT in April 2005. Compliance of the Aircraft to ASTM requirements has been verified by the independent LAMA and FAA audits in Germany.

DGAC of India registered the CTLS in October 2009 for India. November 2009 the CTLS received the Chinese Type Design Approval, issued for the first time ever for an LSA aircraft by the CAAC of China in combination with a Production Approval. And in April, 2012 the CTLS received an EASA Type Certificate!

Since the first flight, over a thousand owners have loved the high cruise speed, low stall speed, and the spacious cabin of all CTs.

Two models – two engine choices! Depending on your specific requirements and preferences, choose either the well–proven, industry–standard Rotax 912ULS, developing a reliable 100 hp with twin carburetors, or the fuel–injected Rotax 912iS featuring a robust 100 hp with the fuel/air mixture precisely computer controlled for ultra–smooth power delivery, improved high altitude performance, more useful torque, reduced emissions and improved fuel economy. The 912iS modern fuel injection also results in surer, easier starts, lower maintenance and lower operating costs all the way to its 2000-hour TBO. Wherever you fly, Flight Design has engine power choices best suited to your exact requirements.
