Key Takeaways:

  • The author reflects on a standout performance at the 2011 FAI World Aerobatic Championship, detailing the precision and thrill of competitive aerobatic flying, a passion discovered through an introductory flight in 1978.
  • Aerobatic competitions involve executing complex maneuvers within an "invisible box" in the sky, with flights judged using the Aresti system, a symbolic language that assigns a numeric difficulty (K-factor) to each maneuver.
  • Competitions are structured into five classes of increasing difficulty and typically include "Known," "Free," and "Unknown" sequences, emphasizing the satisfaction of a clean flight even over winning, akin to a "Soul Flyer."
  • The International Aerobatic Club is highlighted as a key resource for individuals interested in getting involved in the sport, offering regional chapters and sanctioning contests.

How on earth did I get here? This is a question I have pondered many times while flying. Sometimes it’s because nothing is going my way. But on this day in 2011, at the FAI (Fédération Aéronautique Internationale) World Aerobatic Championship in Foligno, Italy, everything was just right.

I was doing circles at 4,000 feet agl in my Extra 300S, waiting nervously for the chief judge to radio me. Soon I would do flips and turns inside an invisible box in the skies in an attempt to impress the judges. As a kid I would spin airplanes around with a remote control. Now I was inside the airplane. The silence ended and I heard the chief judge’s thick British accent: “Contestant 34, the box is yours.”
