Competition aerobatics is an air sport in which ground-based judges rate the skill of pilots performing aerobatic flying. It is practised in both piston-powered single-engine airplanes and also gliders.
An aerobatic competition is sanctioned by a national aero club, its designee, or in the case of international competitions, by CIVA, the Commission Internationale de Voltige Aerienne, which is a constituent body of the Fédération Aéronautique Internationale (FAI).[1] The sanctioning body establishes the rules that apply to the competition, including entry qualifications for all participants, operating procedures, and judging criteria.
A pilot enters a competition in a category of his or her choice, which defines the level of difficulty of the aerobatic sequences to be flown. Within each category, a pilot flies one or more flight programs. Each flight receives a total score from the judges; ranking each pilot's combined total scores for all flight programs within each category determines that category's winner.[2]
