2020 Air Venture - IAC 50 year Anniversary!


EAA AirVenture - July 20th - 26th, 2020 - Oshkosh, Wisconsin USA

The 50th Anniversary of the International Aerobatic Club


This year marks the 50th anniversary of the International Aerobatic Club. It has been an amazing five decades from the early meetings where the club was formed and its founding principles were hammered out, to creation of new programs and plans for IAC that have made it a success for all these years.

The aerobatic division of the EAA, first called the "Precision Flying Division",  was headed by Bill Dodd of Prairie View, Illinois. Its purpose was to promote safety and to be a central point for pilots to join with each other in sharing information. The Precision Flying Division continued until 1969. By the Fall of 1969, Bob Heuer and Don Taylor approached Paul Poberezny about forming a new, formal organization with the EAA structure that went beyond what had previously been done and to begin building membership, new programs, chapters, and competitions. It was to be what the IAC founders called a "grassroots" organization - a part of IAC's culture that has survived to this day.

The first IAC sanctioned contest took place on May 7, 1970 at the Chicago-Hammond Airport in Illinois. It was a one-day competition, a Sportsman-only event with six pilots. The competitors were Don DeWitt (Clipped Cub), Dan McGarry (Clipped Cub), Giles Henderson (Clipped Cub), Dion Stams (Cassutt), Jim Dees (D-260 Senior Aero Sport), and Jim Lacey (Pitts S1-C).

The IAC currently has 40 chapters scattered throughout the United States, one in Alaska and one in Norway. The chapters are the foundation of the organization hosting aerobatic judge schools, practice days, open houses and 38 sanctioned contests last year. Chapter locator. In light of the IAC's aerobatic endeavors around the world, it is easy to think that its main concern lies in major competitions. Though they are an important part of the IAC competition activity, the true story of the IAC's grass roots efforts lies in the  regional competitions it sanctions each year.

IAC members enjoy many benefits of membership some of which are; an aerobatic judges school program, the Achievement Award program (acheivements recognized in non-competition and competition environments), the Collegiate program, government relations representation, a safety committee providing technical and safety tips, and scholarships for aerobatic and upset training.

Join us at AirVenture to celebrate. All are invited to stop by the IAC Pavilion to visit with officers and board members, shop in the store and attend the IAC Forums which run from Tuesday through Friday daily starting at 8:30 a.m.

                                  Friday, July 24th - 6:00 pm to 8:00 pm

Food, beverages, camaraderie, fellowship, and conversation are on the agenda. IAC members, their families,donors and sponsors are invited. The Nature Center is located east of the Museum and Pioneer Airpark as shown in the diagram and is accessed from Waukau Avenue.

Arrival by Aircraft

The 2020 NOTAM which describes AirVenture arrival and departure procedures can be downloaded in a digital version of the NOTAM at www.eaa.org, or order a free printed copy via that website or by calling EAA Membership Services at 800-564-6322.

The NOTAM describes the sign that pilots should bring in their airplanes with “IAC” printed in bold letters. This sign will be shown to EAA Parking personnel so they can direct you to the IAC parking area. It is a simple and efficient system for printing and carriage in your aircraft. Pdf of a sample sign is attached at the bottom of this page for printing.

IAC Aircraft – Bring Your Own Tie-Downs

All aircraft must be tied down and EAA Parking advises us that the best solution is to bring your own tiedowns. Tiedowns are available commercially at the AirVenture site and loaners are also available from EAA, but these sources cannot be counted on if arrivals are “after hours” or supplies run low. Please plan to bring your own equipment. EAA has the “Claw” tie-down device on sale and comes highly recommended.


After Arriving

After being directed to the IAC Parking area by EAA Parking personnel (showing them your “IAC” sign will assist them), pilots should proceed to the IAC Pavilion to check in with IAC personnel, let us know you have arrived, and to sign our Guest Book.

All aircraft should be registered with EAA Aircraft Registration as well and directions will be provided at the IAC Pavilion if you are not familiar.

Site Upgrades at AirVenture 2020

For 2020, a number of significant upgrades have been made to the traffic, parking and tram operations. These changes are based on visitor feedback and from the 2019 Northwestern University Transportation Center study that included input from thousands of AirVenture visitors. The changes include:

  • Easier access and departure from the AirVenture grounds
  • Reducing areas of vehicle/pedestrian conflict within the grounds
  • Improved shuttle service from public lots to the main gate

These maps were created to assist you as you prepare to attend the World’s Greatest Aviation Celebration. Additional updates will be added as they are finalized.
