Glider competition classes
specification for glider competitions
Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports. Instead classes have arisen because of:
the popularity of certain types of glider
attempts to contain the cost of access to the sport
the need to establish a stable environment for investment decisions by both manufacturers and competitors.
The FAI Gliding Commission (IGC) is the sporting body overseeing air sports at the international level so that essentially the same classes and class definitions are followed in all countries.
FAI Competition Classes
Seven glider classes are currently recognised by the FAI and are eligible for European and World Championships:
Open Class, places no restrictions, may be one- or two-seater e.g. JS-1C, Lange Antares 23E, Quintus, ASW 22, ASH 30, LAK-20.
Standard Class, restricted to a maximum wing-span of 15 metres and fixed wing sections (flaps or other lift-enhancing devices not allowed), e.g. ASW 28, LS8, Discus-2, LAK-19.
15 metre Class, as Standard Class with lift-enhancing devices allowed, e.g. ASG 29, LS6, Ventus-3, Diana 2.
This brief starts where responsible research should: with the source description of “Glider competition classes” as specification for glider competitions. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as specification for glider competitions. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q2565860. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
