ATEC 321 FAETA

ICAO code: FAET

This advanced, aerodynamically controlled, two-seat cantilever low-wing aircraft with tricycle fixed gear is derived from the design of our legendary ATEC 122 ZEPHYR. Faeta keeps its fashionable aerodynamic design taking advantage of using the highest quality carbon fibers and the most advanced methods of processing of carbon composites applied on its structure.

Although its design, performance and spacious cockpit give the feeling of higher weight aircraft, in fact it joins the ultralight category mainly thanks to the high quality carbon technology, which guarantees excellent strength characteristics. Keeping high safety factors, this plane complies even with the most demanding weight limits and regulations.

The main difference between Zephyr and Faeta is completely different wing structure. Carbon structure of the Faeta´s wings provides different flight characteristics and helps to reach higher performance. New wing airfoil and plan form enable high cruising speed with low fuel consumption and easy manoeuvrability. Highly effective flaps provide safe flight with extremely low speed and so the pilot can enjoy the landing. Higher amount of carbon composites and sandwich structure with Nomex honeycomb help to keep the low weight.

Fuel tanks in the wings provide higher safety and comfort to the crew. When maximum fuel amount of 100L is filled up, the aircraft is able to reach amazing flight range of 1600/1800 km. Extremely fast and manoeuvrable aircraft provides a high comfort of spacious heated cockpit, which gives a safety feeling to the crew seating side by side.

Small windows situated above the luggage compartment on both sides of the fuselage provide better view and the feeling of open space. Lightweight, but rigid structure allows the plane to be equipped with an advanced ballistic rescue system.

We pay attention to user´s comfort and satisfaction, so we offer a large range of customized interior and exterior design modifications, optional equipment and layout of instruments to be in accordance with user´s wishes, needs and habits. Our intention is to let the client express his creative ideas applied on his own original design and configuration of his new plane. Thanks to adjustable seats and pedals the cockpit is possible to fit to the pilot´s figure.

Because of significant advantage of low fuel consumption, our aircraft can be effectively used for not only comfortable touring or business trips, but also for towing gliders. The plane is popular in pilot schools due to its easy control, manoeuvrability, manipulation and low-cost operation.

Technical details

Wing Sophisticated effective solution

The cantilever tapered backswept wing of an angle of 5,5° with SM 701 airfoil along the whole span is a reinforced shell of carbon composite sandwich with carbon composite coating. The main spar is made of laminated hard beech wood saturated with synthetic resin. Highly effective slotted flaps had been developped using the sophisticated calculation methods. Its control can be either mechanical or electrical. Ailerons have immediate response. Also the flaps and ailerons have all-carbon composite structure. Each structural detail of the wing like flap hinges, slots, Pitot tube mounting, wingtips etc. are designed with regard to minimalize the airdrag. The fuel tanks with the total capacity of 100 L are integral parts of the wings (2x50L). The main spar is welded of high quality CrMo steel tubes.

Fuselage Precise hand-made processing and treatment

The fuselage is all-carbon composite shell braced with carbon sandwich bulkheads, NOMEX honeycomb and hardened foam. The cross-section is elliptic with pure wing fillets and a spacious cabin. The engine in the front part of the fuselage is separated from the cockpit by the firewall, to which the engine mount and steerable nosewheel are attached.

 

Tail unit Tested for flutter up to 600 km/h

The tail unit is all-carbon composite T-shaped construction which consists of tapered horizontal tailplane with fix stabilizer and elevator. The elevator trim can be either mechanical or electrical. The tapered tail fin is an integral part of the fuselage. The rudder is suspended to the last fuselage bulkhead.

Landing gear High flexibility

The landing gear is a fixed tricycle undercarriage with a steerable nose wheel. The main gear is designed as a pair of composite leaf springs tested for the load of 550 kg. The integral nose leg is made of composites and metal tube with shock-absorbing rubber springs. The main wheels are equipped with hydraulic disc brakes. The electronic main wheels size is 350x120 mm, nose wheel size is 300x100 mm. Aerodynamic fairings are installed on all wheels.

Controls Easy and manoeuvrable

The steering of all controls is dual. Ailerons, flaps and elevator are controlled by rods and levers, the rudder is controlled by stainless steel wire ropes. All controls are designed the way not to disturb the pure outline profile of the airframe. Important checking points in wings are equipped with inspection holes with perspex covering.

Propulsion Incredible performance and consumption

We standardly install ROTAX 912iS SPORT 100HP, ROTAX 912 ULS 100 HP or ROTAX 912 UL 80 HP engines in configuration with three- or two blade FITI propeller, which can be fix, ground adjustable or adjustable in flight, with manual or electric control and availability of Constant speed system. The engine compartment is separated from the cockpit by the firewall. The engine mount is welded of the first-rate-quality CrMo thin-walled steel tubes.

Fuel system Exceptional safety solution

The fuel system consists of two fuel tanks in wings with a total fuel capacity of 100 litres (2 x 50L). All the fuel system is installed outside the cockpit area. The piping connection is equipped with a sediment bowl and a drain plug. The fuel supply is secured by two independent circuits and pumps. The fuel pressure is monitored by the pressure gauge. The previous aircraft version having only one central fuel tank (capacity 70 L) integrated in the fuselage is still available upon request.

Instruments Enjoy your favourite music or movie during the flight

Instruments provide a wide range of alternative custom solutions. We offer basic analog instruments or the most advanced glasscockpit electronic systems for the flight and engine monitoring (EFIS, EMS) and navigation up to the screen size of 9 inch, USB connector, MP3 and movie player. The plane can also be equipped with position recorder, 3-axis autopilot, various types of GPS, radios, transponders, ELT, stall warning etc... The static and dynamic pressure is taken from the Pitot tube installed on the underside of the left wing. The dashboard is standardly equipped with 12V plug and USB connector for your iPad.

Cockpit Luxury comfort

Whole the cockpit is upholstered with a special fabric containing nanofibers. The advantage of such smooth, comfortable material is its easy cleaning, high resistance, long life-time and surely also its light weight. It is available in various colours and their combination is individually customized. We offer two types of ergonomic seats. The standard „car“ seats are easily adjustable up/down. The second type consists of carbon shell with removable cushions attached on velcro. The cushions thickness is customized. This type is adjustable forward/backward using the lever mechanism on its underside. The pedals are adjustable in 3 positions. The cockpit can be optionally equipped with the second control stick on passanger´s side. The side walls are fitted with armrests and net pockets. The spacious luggage compartment behind the seats is easily accessible during the flight. Its loading capacity can be optionally increased by the modification of the space behind the pilot´s seat. Two ventilators installed on the dashboard assure effective air-ventilation and heating. The floor on passanger´s side is adapted the way to provide a higher comfort also to the legs.

Canopy Enjoy a beautiful view all over the landscape

The canopy is made from perspex containing UV filters. Both sides are fitted with small sliding windows. It is offered in colourless or tinted versions. Demisting fan on the top of the dashboard helps to keep good visibility. The canopy opens up- and backwards. Electrical blocking system disables to start the engine in case the canopy is not properly closed and locked. Mechanical blocking system prevents from self-opening during the flight. Aerodynamic canopy hinge prevents the paint from scratching.
