Over the years, with advances in aircraft design, an internationally recognised sport has developed:- Competition Aerobatics. The sport should not be confused with the kind of aerobatics seen at airshows, commonly known as ‘stunt flying’. Competition aerobatics is a very exacting sport which demands high levels of skill, discipline and concentration on flying. A predetermined sequence of manoeuvres is carried out in a small cube of airspace known as the ‘aerobatic box’. Pilots can fly at different levels of competition from Entry Level to Unlimited depending on their level of skill and the performance capabilities of their aircraft.
