DIMENSIONS
The innovative ONE aircraft has been designed with a passionate pilot in mind, who seeks to take advantage of any favourable weather forecast for a randez-vous with birds. In order to achieve the best possible comfort for the pilot, who can during a route flight with ONE aircraft stay in the air for the total of up to 9 hours, the aircraft is equipped with adjustable rudder pedals as well as with adjustable seats. All this gives to any pilot between 163 and 202cm in height the feeling of a home comfort.
The plane also offers a lot of room for the front fellow passenger. The back seat can be used as baggage space or you can also take a child or a smaller person with you (up to 90 kg). In case the plane is to carry three persons, some of the baggage can still be stored in the small baggage space behind the back seat.

SAFETY
ONE is designed to be the ultimately safe, attractive, affordable and top performing small aircraft. The idea to design ONE started from personal requirements, which during the process grew into an ambition to set new standards in light aircraft design and use.
Its roots, construction and design solutions were chosen on the back to basic conditions with the following features that were fundamental to the design:
- Extreme safety of passengers,
- intelligent construction design,
- comfortable and quiet interior,
- top class performance,
- high-end avionic equipment,
- splendid visibility,
- ISOFIX connection for child seat,
- and excellent flying characteristics, that will provide our user with ultimate sense of satisfaction and freedom yet will still be affordable to both acquire and to operate.
Safety Features
Even in its basic configuration, ONE is equipped with a lot of safety features, such as:
- airframe parachute
- 3D passenger compartment roll safety cage
- doors designed to be opened in case of a roll-over
- full Kevlar cabin interior for protection from object penetration
- “single-spar” design – both spars overlap and are bolted together to the fuselage, adding to construction stiffness and safety
- FEM designed and tested cabin construction with car-style crash resistance
- 4 mm certified glass front windshield for bird and other object penetration protection
- intelligent engine management (when throttle is applied, you touch choke, parking brake and carb heat if they are applied – ON)
- Panel retracts in case of crash
- three hinges on every moving surface – four on the flap
- glide ratio of 17.5 for lower fuel consumption and higher safety in case of engine failure
- adjustable seat and pedals
- grouped switches with clearly recognizable positions
- integrated emergency release out of the way, easily accessible
- warning lights in best eye scan position between inside and out
- glove compartment to store POH, camera or additional charts behind (optional) iPad mount
- side-sticks (optional in experimental version), centre-stick standard


ONE FOR YOU
Our engineers have aspired for ONE to be the best aifcraft in its category. After many years of designing and testing, they have managed to build a perfect light aircraft ONE. Once you test it out for yourself, you will discover it is perfect for you, too, as you can have it tailored to give you serious thrill and enjoyment out of flying. It will provide ultimate pleasure for the lone pilots who prefer to fly solo, as well as those who wish to share their passion with the ones closest to them.
As ONE meets the highest standards of quality, it will make your journeys even more comfortable.
SOLITARY PILOTS
ONE aircraft is suitable for pilots who fly solo. You can choose between ONE with the centre or side control sticks. Pedals and ergonomically designed seats can be adjusted for your maximum comfort in a spacious cabin and there is enough space to store all the luggage for a long trip away. You’ll also have plenty of room for a quiet read of maps while autopilot safely leads you through the sky.
COUPLES AND RETIRED PILOTS
ONE aircraft is the perfect choice for couples. It is ideal for retired pilots, who can continue to enjoy their passion with ONE. Instead of buying a campervan on wheels, you can enjoy a motorhome in the air and fly your friends or loved one off to new adventures. There should be enough space for all your luggage and perhaps you can take along your grandchild or even your pet.
PILOTS WITH COMPANY
ONE aircraft is loved by pilots who like to keep company. In addition to the passenger sitting next to you, you can also put your off-spring in the back seat. With the help of ISOFIX system even your youngest one sleeping in a car seat can go along. In spite of the passenger, you can still store some luggage in the luggage space behing the rear seat.
FLIGHT TRAINING
ONE aircraft is a smart choice also for learning to fly at flight training schools, as this little aircraft possesses everything that its larger counterparts have. The pilots who will be trained on this plane will not have any problems with the transition to a more powerful or more complex aircraft.
ONE – COOL TO OWN
ONE aircraft looks cool – at the airport and in the air
Taking it out of the hangar or walking around it on a preflight will render speachless even the birds flying above your airfield (well, we might have exaggerated a tiny bit here).
Sure enough, everyone will look at your aircraft with sparkles in their eyes. Looking beautiful, one already feels the great flying characteristics ONE can offer – simply by looking at it. Streamlined, simple, yet technically advanced, without unnecessary quirks and corrections, ONE looks cool at the first glance and proves all that by performing great in the air.
With custom Exterior design options, ONE can even be personalized!

PRACTICAL AND SAFE ONE
If you expect to use ONE for more than just flying local, you might need a large luggage compartment with clever ways (i.e. folding backrests) to store golf bags or skis, suit cases for travelling or even to pick up the whole family (see above). ONE also features a smaller cargo compartment that is separate from the cabin and accessible from the outside (also above, under the S5-MAO registration marks) where the aircraft fluids are located, (oil, cleaning material, drain, aircraft cover, etc., ). 8+ hours of fuel are carried on board, which is great if there is no fuel at the destination or only expensive AVGAS is available.

Professionally designed cabin features also an ergonomic armrest, supporting the hand in a relaxed position (supported not in front of the abdomen, but angled a little bit forward on the side). Such armrest position gives enough space for effortless movement of the hand and enables a good view of the instruments and ease of use of an i-Pad or kneeboard. Most of ONE aircraft will also be equipped with the affordable Dynon autopilot.
