The FAI's Aerobatics Commission, CIVA, elected to use the catalog beginning at the World Aerobatic Championships held in Bilbao, Spain in 1964; it has been in use worldwide and has evolved continually since then. Though the catalog had grown at one time to some 15,000 manoeuvers, a CIVA working group substantially streamlined it in the mid-1980s. Following Aresti's death, a court fight ensued between his heirs and FAI, which once provided a free catalog online. The catalog is now only available in printed form for a fee from Aresti System S.L.  Software is available to design and display aerobatic sequences using Aresti notation.
