– CTLS –

The Airplane

flight design aircraft

The CTLS is one of the most popular light aircraft in the world due to its great overall performance, sporty handling and class leading safety features. The new CTLS 2020 Sport Edition is now even better due to the new developments for 2020!

Lighter empty weight, a new interior, redesigned cowling and Garmin G3X avionics suite are just a few of the improvements on this updated model. The flexibility of the design is evident from that fact that it can be flown as an EASA CS-LSA Restricted Type Certified aircraft, a 600 Kg Ultralight or a Compliant SLSA!

The CTLS 2020 SE incorporates evolutionary changes that make it an even better airplane for the demands of professional flight schools, flying clubs as well as private owners. It was our mission to improve the CTLS 2020 SE’s performance and reduce empty weight without sacrificing what pilots love about the CTLS. The CTLS 2020 SE rigid carbon fiber cockpit forming a safety cabin, plus four-point harnesses. The standard airframe emergency parachute system (AEPS) is an important addition to the list of safety features on the CTLS 2020.

Advanced Aerodynamics

The carbon/aramid fuselage on the CTLS is optimized for large internal space for the cabin and to reduce drag while providing cleaner airflow to the stabilizer. The smooth cantilever strutless wing also reduces drag and allows maximum visibility from the cockpit. Winglets improve climb, cruising range and aileron control at low speeds. The attractive new cowling and spinner improves cooling and reduces drag while improving access to the powerplant. While the top speed of the CTLS 2020 SE is impressively high, all CTLS fly with efficiency and low fuel consumption at all speeds.

Land with Confidence

The advanced composite main gear is extremely strong and rugged while also being flexible, absorbing over 50% of landing energy on the first rebound. Urethane polymer shock absorbers in the nose gear give high dampening and help to smooth out hard landings.

Flight schools and Flying Clubs

The CTLS has long been popular with Flight schools and Flying clubs due to its low operating cost, easy flight characteristics and large comfortable cabin. The CTLS 2020 is now available for more training uses due to all versions approved as an EASA CS-LSA Restricted Type Certified aircraft, as a 600 Kg Ultralight and a Compliant SLSA.

Please Fly Safely

The Flight Design engineering staff created the CTLS with safety, performance and comfort in mind. The cockpit’s carbon-aramid composite cabin helps to protect you and your passenger. The engine mount and carbon fuselage attach points reduce the possibility of engine intrusion into the cabin area. Standard four–point harnesses along with crushable elements of the fuselage construction absorb energy and reduce possible loads to the pilot and passenger.

Strong windshield uprights and massive upper construction complete the protective environment. Fuel tanks are sensibly located in the wings, well away from the pilot and passenger. Numerous improvements to the CTLS 2020 fuel system are incorporated to give proper fuel flow even in extreme conditions while maintaining the safety of the single lever operation.

The CTLS has been subjected to numerous static tests and complete flight–testing as a part of certification to major Airworthiness Standards including ASTM–FAA Light Sport Aircraft requirements, CAAC type and production certificates, EASA CS-LSA and German LTF–UL. Each CTLS is fully flight tested by our engineering test pilots and flown again after being reassembled and checked by factory trained experts in the country of destination.

Two models – two great engine choices: CTLS 2020 SE Rotax ™ 912S, CTLSi 2020 SE Rotax ™ 912iS

Depending on your specific requirements and preferences, choose either the well proven Rotax 912ULS, developing a reliable 100 hp with twin carburetors, or the fuel–injected, Rotax 912iS, featuring an advanced 100 hp with the fuel/air mixture precisely computer controlled for ultra–smooth power delivery, improved high altitude performance, more useful torque, reduced C02 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.
