Kharkiv KhAZ-30
type of aircraft
The ViS ViS-3 is a high wing, single-engine ultralight, designed and built in Ukraine. The production version is designated as KhAZ-30 (ХАЗ-30).
Design and development
The ViS-3 is a two-seat, side by side, conventionally laid out ultralight high-wing monoplane. It first flew on 8 October 2006 and its flight test programme led through the revised ViS-5 to the Kharkiv State Aviation Plant built KhAZ-30 (ХАЗ-30) production aircraft, which first appeared in public on 22 May 2012. The development programme has brought small but significant changes to the design, chiefly in the removal of forward sweep and the addition of dihedral and flaps. It is mostly of metal construction, though with fabric-covered wings. These have straight edges and constant chord and are braced by a single streamlined strut on each side, forward leaning from the lower fuselage to the wing.
The fuselage is noticeably shallow, with a long cabin glazed ahead and behind the wing, both above and to the sides. A 73.5 kW (99 hp) Rotax 912 ULS flat four engine in the nose drives a three-blade propeller. The rectangular tailplane is set well back; the ViS-3 had mass balanced elevators, developed on the ViS-5 to include aerodynamic (horn) balances and slightly increased in span.

Why this record matters
The phrase “type of aircraft” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 26, 2026. The linked authority identifier is Q16721874. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006 and 2012.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
