Design and development

The Via was designed to comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a cantilever low-wing, an enclosed cockpit with two-seats-in-side-by-side configuration under a bubble canopy, fixed tricycle landing gear and a single engine in tractor configuration.^[1]

The aircraft is made from sheet aluminum. Its 8.13 m (26.7 ft) span wing employs a MS 316 airfoil at the wing root, transitioning to an MS 313 at the wing tip. The wing has an area of 10.5 m² (113 sq ft) and mounts flaps. The cockpit is 130 cm (51 in) in width. Standard engines available are the 80 hp (60 kW) Rotax 912UL, the 100 hp (75 kW) Rotax 912ULS, the turbocharged 115 hp (86 kW) Rotax 914, 100 hp (75 kW) Continental O-200 and the 130 hp (97 kW) ULPower UL350i four-stroke powerplants.^[1][2]

As of March 2017, the design does not appear on the Federal Aviation Administration's list of approved special light-sport aircraft.^[3]

Operational history

Reviewer Marino Boric described the design in a 2015 review saying, "the fuselage lines are very smooth and the aircraft looks elegant like a composite made aircraft."^[1]
