The Aresti system of symbols has become the standard for the international aerobatic community. Devised by Jose Louis Aresti in the early 1960's, Aresti symbols are used by pilots to communicate aerobatic maneuvers to other pilots and judges so they can keep track of them.
The system consists of 14 "families" of figures, and within each family are many variations. For example, family 1 consists of 68 types, and family 2 includes 60 variations. Just as you'd imagine, basic figures are combined to create thousands of maneuvers and sequences.
Here are some basic figures from the first 9 families, and a legend that indicates what the general symbols represent. Below them are some current Aresti diagrams from notable airshow performers.
