High speed & great skills
It is not only a high speed of passing the route that is regarded as a peculiar feature of air races but accuracy as well. A minor error may result in fine points. Highly accurate maneuvers of pilots at the lowest heights presuppose great skills, which are typical of the most deserving representatives of the discipline.
A possibility of the route adjusting to holding events makes air race a unique venue for demonstration and testing new technologies as well as current construction innovations.
