The International Aerobatic Club has a practice and competition area just north of the airport. The area was designated in 1976 and has a waiver from the Federal Aviation Administration. Aerobatic pilots from California and the southwest US regularly use it for practice and major competitive events; users have included three past national champions. Visitors are welcome to come to the airport and watch the flight activity, which does not interfere with other operations. Two annual competitions are sponsored by the San Diego Aerobatic Club, in April and October.
