Come and explore its features with us.
The comprehensive equipment of the ergonomic cockpit is complemented with electrically operated flaps, trim and autopilot. The highest level of safety of the crew and aircraft is assured with a rescue parachute system for the entire plane (AEPS). ATTACK VIPER SD4 version RTC and NVFR has demonstrated compliance with CS-LSA Amdt.1 and has been awarded a type certificate by the EASA (certificate number EASA.A.606).

ENGINE
Rotax 912 ULS
The best selling 4-stroke aircraft boxer engine produces 100 horsepower with 4 opposing pistons, fed by twin carburettors, with 2000 hours time between overhauls. This engine is currently the most attractive balance of low weight and optimal performance. For added safety, the engine is equipped with dual ignition and forced lubrication with a separate oil tank and a de-foaming device.

Safety Package
Total Safety
Flying is the safest means of transport, which is being pushed to the next level by the unique Safety Package installed in every ATTACK VIPER SD4 aircraft.
The T-CAS system will alert you of air traffic around you and to possible collision risks. A loss of electrical power on board will be mitigated with a battery powered backup screen. In case of engine failure, the “NEAREST” function combined with “GLIDING RANGE” informs you of the closest landing areas you can reach by gliding thanks to the impressive gliding capability of the aircraft – 8 km from the height of 1 km. The VNAV profile will guide you to the start of the runway. In a worst case scenario, you can activate the parachute where the entire aircraft will be securely carried to safety, and subsequently the ELT function will automatically inform the rescue service of the aircraft's position.

Glass Cockpit
Full Control
Set in lightweight carbon-fibre, the advanced configuration of flight, navigation, communication and industry-leading monitoring systems of the highest standards are combined with touch screen and manual controls. This offers the crew an unprecedented feeling of complete control from both seats thanks to two functionally identical 10'' - 25,4cm Garmin G3X Touch screens, complemented with a smaller central battery powered backup Garmin G5 monitor. The up-to-date airport database with trajectories and frequencies, can be tuned automatically via the on-board radio depending on your position, as well as the possibility to view the terrain and receive warnings of obstacles and traffic along your route, adding to the wide range of practical features.
ERGONOMICS
Luxurious Cockpit
An effortless entry into a spacious ergonomic cockpit gives an intelligent layout of control components, the impressive looks are enhanced by the carbon-fibre instrument panel with two large Garmin monitors and a backup screen in-between. Not only are the luxurious seats leather upholstered, but also the control levers. Glare is prevented using covers made of Nubuck leather. You can store your hand luggage conveniently in two safe compartments with sliding aluminium shutters.
EFFICIENCY
The Economics in Perspective
From Bratislava to Prešov it takes 4 hours 15 min and costs €62 in a luxury car of the same price as the plane, if the traffic is clear, that is usually not. It isn't any better by train either. But as the eagle flies, it takes only 1 hour 23 min in the aircraft, costing €33, while in the sky, there are no traffic lights, traffic jams, detours or roadworks.

PARAMETERS
Technical Advancement
Careful manufacture on top-of-the-line CNC machines and high quality craftsmanship focussing on precision, safety and customer satisfaction are the key ingredients for constructing the metal body. Proven by many years of use, the body reliably resists UV radiation, it does not crack and achieves longer service life than the carbon-fibre alternative, while also allowing damaged parts to be replaced.
