The FIS Ski Flying World Championships is a competition that is held every two years, with the occasional exception. The Championship takes place in big ski jumping hills, with K-spots over 185 meters. Unlike ordinary ski jumping, the Ski Flying World Champion is determined after four jumps. 40 jumpers qualify for the competition and jump the first round, 10 are eliminated, and the 30 remaining jumpers compete in the last three rounds. The person with most points combined after four jumps is declared the World Champion. In 2004, FIS introduced a team event between National teams of four jumpers, with two jumps each.
