The Flight Design CTLS

The Next Generation from the Market Leader

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 1700 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.

However you fly, Flight Design has engine power choices best suited to your exact requirements.

SERVICE

The new engine mount and control system design was developed with service and repairs in mind. The CTLS requires only a minimum of maintenance. At our Service Centers you can have this work done by our properly trained staff. You can also participate in an owner-training course at one of our Flight Design Service Centers. This course will enable you to do simple maintenance yourself supported by our detailed maintenance manual and parts manual supplied with each CTLS.

Our local Service Center technicians are available for specialized work and repairs or to assist local mechanics on the basic maintenance of the CTLS.

GLIDER TOWING

Since the beginning of the glider towing tests in Europe, the CTLS has shown surprising aptitude. The climb speed is just right for comfortable climbs with gliders under tow. The CTLS has demonstrated this even on grass with a fixed pitch propeller.

DURABILITY

A modern airplane should be built with modern technology. Carbon fiber-epoxy aircraft construction offers unparalleled strength, durability, corrosion and fatigue-resistance. Despite high material and labor costs, carbon fiber construction is being used more widely every year. Due to its advantages, carbon fiber construction has been adopted for many new military and commercial aircraft replacing older aluminum & rivet construction. Repair costs with carbon fiber construction are typically far less than those for conventional metal or tube and cloth aircraft. New core foam which is now used is much more resistant to environmental damage.

Repairs can be locally performed around the country.

The CTLS is finished in a two-part polyurethane paint, which is very UV-resistant. Beautiful and easy to take care of, the CTLS polyurethane finish will last years when properly maintained.

CT SAFETY CABIN DESIGN

The design of the CTLS carbon fiber cockpit has been intentionally done following reliable design principles known from the passenger cabins of modern cars, where crash loads are transferred through the passenger area to the crash-zones at the end of the vehicle, so that the cabin remains stable while the energy is absorbed in the periphery areas.

Looking at the CT models safety cabin you can find all key car design features as well.
The following illustration generalizes the force flow in the CTLS:

• Forces are introduced in a crash from the engine and nose gear through the big engine mount (1) into a strong A-pillar (2) and to the center tunnel (5).

• The door sill (3) is designed to transport the loads backwards and into the sandwich composite shell.

• The fuselage root rib area (4) is designed as a stiff roof rail to transports the loads backwards.

• The middle of the cabin is stiffened with a tunnel (5) that extends from the nose gear attachment area to beyond the luggage compartment.

• The cabin is closed at the end with the main bulkhead (6) that serves together with the door sill as B- pillar. All longitudinal elements extend to and beyond this main bulkhead.

• The floor section below the seats is designed with “Pyramids” (7) installed to the cabin floor, supporting the seats and stiffening the floor.

• The inner laminate of the cabin skin is done in aramide, providing best occupant protection against splintering. The outer skin is designed as carbon fiber providing maximum stiffness and strength.

The suitability of this design has been proven in service now for 13 years. Accident history shows that the cabin provides a maximum of occupant protection even in a severe crash.

GET COMFORTABLE!

The 1.24 m (49-inch) cabin width of the CTLS has been increased in length to fit very tall and smaller people equally well. People with heights of 1.55 to 2.00 m (5′ 1″ to 6′ 6″) sit more comfortably than ever. More storage space in the cockpit is provided by a new convenient jacket shelf for in-flight access and bigger outside baggage doors now give better access for bulky items stored aft of the cockpit. Two new windows in the rear give the cockpit a more open feeling and greatly improve rearward visibility.

Large gull-wing doors held up by gas struts make entering and taking your seat easy. Three-point latches and door seals keep you secure inside. Comfortable seats with molded foam padding and pneumatically adjustable seat cushion and lumbar sections offer incomparable comfort and easy adjustment in height and length. From these seats, the remarkable visibility of CTLS will give you the feeling that you are in a helicopter with a sweeping view of the world.

The new engine installation reduces vibration and cabin noise is reduced further. Full dual controls and centrally located throttle quadrant are features of this ergonomically arranged cockpit. Easy to reach storage space and convenient map holders are thoughtfully provided. Standard ventilation and heating allow CTLS flying in all seasons.

The CTLS allows up to 50 kg (110 pounds) of baggage (total) to be safely stored in the dual storage compartments aft of the cabin area.

If you are finding it hard to find a Light Sport Airplane that fits you, try the CTLS. We think you will be pleasantly surprised.

STRUCTURE

 The CTLS structure is made from the very latest carbon fiber construction with rigid foam core and epoxy matrix using vacuum technology. All supporting structure consists of carbon and/or aramid fibers, and since 2008 a new foam core material is used in exposed areas to provide improved resistance against weather, fuel and chemicals. All materials used in the construction are from Western suppliers and correspond to either DIN or Aviation standards. The CTLS wing surfaces are post cured at 80°C (176 degrees) as it is customary in aircraft construction. 

PRODUCTION

Production of the CTLS is performed in Ukraine by our young and highly motivated staff near the legendary Black Sea. Along with the development of the original CT, our own R&D and manufacturing company was created. We are constantly expanding our production facility and staff to meet the growing demand. Ukraine has a strong aviation culture going back to the beginning of manned flight. Major airframe and component manufacturers are now sourcing engineering and manufacturing in Ukraine to take advantage of low production costs as well as one of the world highest engineering educational standards. 

The balance of safety and performance is attained through rational design, well-organized manufacturing and the use of dependable Western materials. 

CTLS was designed and tested using the most advanced CAD programs available and these systems are also applied in the production of the aircraft. We are proud to be at the vanguard of aviation technology and a leader in bringing that structural and aerodynamic technology to the light plane industry.

PLEASE FLY SAFELY!

The Flight Design engineering staff created the CTLS with safety, performance and comfort in mind. A new aircraft should employ modern construction techniques for many reasons.

The carbon-aramid composite safety cell helps to protect you and your passenger. The engine mount and carbon fuselage attach points reduce the possibility of engine intrusion into the cell.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 occupants. Numerous improvements to the CTLS fuel system are incorporated to give proper fuel flow even in extreme conditions while maintaining the safety of single lever operation.

The wide speed range and high structural margin of the CTLS give you peace of mind even in the strongest conditions. Tested and certified to perform up to 600 kg (1,320 pounds) the CTLS can take the load and haul it, too!

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 and German LTF-UL 2003. 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.

HAPPY LANDINGS!

New urethane polymer shock absorbers in the nose gear give high dampening and help to smooth out hard landings. The new composite main gear, developed and produced by a certified aerospace supplier is rugged and absorbs more than 50% of the energy on the first rebound.Five–axis CNC milling technology produced the metal molds for the new composite main landing gear. New tires developed together with our partners give the correct balance of durability, performance and light weight.

AERODYNAMICS

The fuselage on the CTLS is 390 mm (1′ 1″) longer, which increases pitch stability and dampening significantly. The result for pilots is a smoother ride in turbulence and much easier landings.

By optimizing the shape of the fuselage, drag has been reduced while cleaning the airflow to the stabilizer. The smallest improvements were executed to further increase lift and reduce drag.

The stabilizer trim tab incorporates a new flexible elastic hinge, which is aerodynamically cleaner plus the control linkage has improved gearing for finer control and better trim feel.

The wing of the CTLS uses the same efficient airfoil as the CTSW. Advanced winglets reduce induced drag, improving climb, cruising range and aileron control at low speeds while conveying a 21st-Century look.

In total, the aerodynamic changes have improved the CTLS’s stability and its ease of flying significantly. While the top speed of the unlimited CTLS is impressively high, all CTLS fly with efficiency and low fuel consumption at all speeds.
