ALTO NG

New version of the popular all metal ALTO aircraft is the outcome of the new Czech certification UL-2 with 600 kg MTOW. There has been no change to the flight characteristics and handling qualities of the aircraft, the aircraft has been improved thanks to more than fifteen years of experience with the aircraft in operation by flight schools, aeroclubs, new and experienced pilots in the Czech Republic and abroad.

There has been change of length and design of engine bed and cowling, front leg and fuselage have been both stiffened. The elevator control system has been modified as well. Control cables are not used anymore, push-pull rods were integrated instead.

All-metal Aircraft with 600 kg MTOW

ALTO is a single-engine, two-seat, self-supporting monoplane. The aircraft was designed as a simple all-metal design suitable for assembly in amateur conditions, yet providing sufficient performance, corresponding to the standards in this category, low maintenance costs and easy and comfortable flight control. The aircraft is equipped with a proven ROTAX 912 ULs engine, providing sufficient power in its category. GALAXY GRS rescue system and glider tow can be installed upon request.

Direct Fly currently only produces the ALTO NG version, production of previous ALTO 912 TG model was terminated in 2022.

Wing

The advantages of ALTO lie in its simple and comfortable piloting, which is guaranteed by the design of the wing. The rectangular wing plan and the profile with a blunt leading edge provide predictable stall characteristics and behaviour. The wing is a semi-monocoque structure and is equipped with built-in tanks with a capacity of 92 litres of fuel.

Fuselage

The rear of the fuselage is designed with a rectangular cross section with an oval upper surface. The stiffness of the structure is secured by diagonal webs. The wing-fuse link is conceived as the interconnection of the wing beams with the center plane of the airplane by means of flanged bolts.

Tail surfaces

The horizontal and vertical tail surfaces are of a traditional arrangement. They are made as a riveted structure with composite end arcs.

Flight controls

Flight control transmission from the "stick" is realized by means of rods and cables. Directional steering of the front landing gear leg is coupled with pedals for changing the aircraft direction. The brakes are hydraulically controlled by a lever located on the center panel.

Landing gear

The landing gear is designed as three-wheel, with front steering wheel. The main wheels are fixed to the fuselage on flexible laminate legs.

Cockpit

Access to the cockpit is secured by means of footpaths located at the trailing edge of the wing. The spacious, 110 cm wide cockpit provides plenty of room for comfortable control of the aircraft. The cockpit roof slides forward and it is mounted on rails.

Alto Offer

ALTO NG, as its predecessor, is available in three completition stages, as a disassembled BASIC KIT, assembled airframe as QUICK KIT and fully assembled aircraft as READY TO FLY. Each kit is complemented with appropriate drawing documentation and detailed manuals.

From the very beginning Alto has been designed as a very simple all-metal aircraft suitable for building in amateur conditions, without the need for special workshop equipment and tools. For experienced builders we offer the disassembled ALTO kit.

BASIC KIT

The disassembled ALTO BASIC KIT is suitable for experienced builders. It includes all the parts needed for the airframe – wings and aircraft fuselage. All parts are machined on CNC milling cutters, bent, folded, pressed and welded. For building the aircraft from this kit, the usual workshop equipment – flat table, agraffes and suitable pliers is sufficient.

CURRENT PRICELIST

QUICK KIT

Fully finished aircraft airframe. The builder installs the engine, avionics, interior, finishes the canopy and installs electrical and fuel parts and paints the aircraft. It does not include the engine, engine bed, electrical installation, instrumentation, ventilation controls, heating, upholstered seats, seat belts and varnish. However, extra kit parts can be ordered at the customer's request.

CURRENT PRICELIST

READY TO FLY

Finished aircraft equipped with the Rotax 912 ULS engine and all other installations. In default configuration, the aircraft is equipped with hydraulic brakes with a central control lever, electric flap control and electric trim on the horizontal rudder. The exterior of the aircraft is made in a single color spray, the interior and the seats are upholstered with cloth.
