The Aresti Catalog is the Fédération Aéronautique Internationale (FAI) standards document enumerating the aerobatic maneuvers permitted in aerobatic competition. Designed by Spanish aviator Colonel José Luis Aresti Aguirre (1919–2003), each figure in the catalog is represented by lines, arrows, geometric shapes and numbers representing the precise form of a maneuver to be flown. They are similar to notes on a musical score, except in this case the "notes" represent aerobatic maneuvers. The figures are generally read from left to right and top to bottom, but occasionally there are dotted lines connecting figures when the order might otherwise be confusing.
Airshow sequences often include maneuvers such as tumbles and torque rolls that are not represented by Aresti notation, because they are not competition maneuvers, so airshow pilots have to improvise a little bit on the notation.
