Orličan VSO 10
1970s Czechoslovakian glider
The VSO 10 Vosa (Vosa – Gradient) is a Standard and Club-Class glider designed and manufactured in the Czechoslovak Republic from December 1978 as a replacement for the VT-116 Orlík II.
Development
Development of the VSO 10 started in 1972 and the first prototype flew on 16 September 1977. The Type Certificate was granted on 15 May 1979, with the first production gliders entering service with Czechoslovak aeroclubs soon after. In 1990 the company ceased production when they started to build Schempp-Hirth gliders. Schempp-Hirth are the current holders of the VSO 10 Type Certificate.
Design
The VSO 10 is a mixed-construction glider with wooden and steel tube structural members, aluminium alloy rear fuselage and glass-fibre sandwich skins. The wings are shoulder-mounted and the tailplane is mounted on top of the integral fin. Conventional control surfaces include all-wooden slotted ailerons, all-metal DFS airbrakes on the upper and lower surfaces of the wing and fabric-covered all-metal elevators and rudder. The undercarriage in the Standard Class aircraft is a manually retractable rubber-sprung monowheel with a drum brake, (non-retractable in the Club-Class aircraft), with a rubber-mounted steel skid under the tail. The pilot is accommodated in a fully reclined seat under a two-piece canopy. Provision is made for 56 L (15 US gal; 12 imp gal) of water ballast to optimise cross-country performance in strong lift conditions.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Orličan VSO 10”, the useful work is to connect “1970s Czechoslovakian glider” to the records capable of establishing context and consequence.
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 Jun 16, 2026.

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
