The International Gliding Commission (IGC) is the international governing body for the sport of gliding. It is governed by meetings of delegates from national gliding associations.
It is one of several Air Sport Commissions (ASC) of the Fédération Aéronautique Internationale (FAI), or "World Air Sports Federation". FAI is the world body for sporting aviation and the certification of world records for aeronautics and astronautics and was founded in 1905.
When the IGC was founded in 1932, it was called CIVV (Commission Internationale de Vol à Voile) and has also been called CVSM (Commission de Vol Sans Moteur). It is the FAI commission responsible for the international competitions, records and badges that apply to gliders and motor gliders. The term "sailplanes" is sometimes used. Hang gliders and paragliders have a separate body called the FAI CIVL Commission, which stands for "Commission Internationale de Vol Libre".
The World Gliding Championships are organised every two years or so by the FAI Gliding Commission and the host nation.
Within FAI, the sport of glider aerobatics is managed by the FAI Aerobatics Commission (CIVA), which stands for "Commission Internationale de Voltige Aérienne" and also deals with powered-aircraft aerobatics
In the early 1920s two flying organizations, the Association of the German Model and Gliding Clubs, and the Rhön Soaring Association, determined that pilots would be listed as "A" level if they flew a glider for either 300 meters or 30 seconds, and "B" level if they made two flights of 45 seconds in straight lines plus one of 60 seconds in an "S" pattern. (It should be remembered that these flights were made by bungee cord launches down hillsides.) In time a "C" level, requiring a five-minute flight, was added. A few years later Fritz Stamer, chief flight instructor of an early gliding school, designed the gull insignia which were used for these awards and later for the badges.
