We rent a large hangar from the airport for the contest, Thursday - Sunday. If you want your airplane in the hangar, be sure to sign up when you register. First come, first served, $30 per night. As happens at every contest, we are 99% certain that all of the Pitts fit in, 50% sure that the Extras, Edge's, and Lasers will fit, and we try to fit Decathlons in too. There are usually tie downs available on the ramp, but if in doubt, bring ropes. If this is your first contest, be advised that the IAC contest rules do not allow you to commute home at night in your aerobatic aircraft. Plan on being parked at the contest for the duration.

As in past years, a block of rooms has been reserved at a cost of $142 /night plus taxes.  Make your reservations directly with the Hotel, (802)885-0402 Ext 4516, via e-mail,  but not through the national reservation number and ask for the "aerobatic contest rate". July is a busy time for the Best Western in Springfield, and it is advised that you book early.

The Hartness House Inn is near downtown Springfield; (802) 885-2115.

For the minimalist traveler there is the Crown Point Camping Area in nearby Perkinsville.

For the luxury traveler, just north of the airport, there is The Inn at Weathersfield, 802-263-9217.  This is a very nice Bed and Breakfast located within walking distance (10 minutes) from the airport.  Great restaurant also. Includes a full breakfast.  Ask for Richard and identify yourself as an Aerobatics Contest participant.

For the pilot: All of the aircraft and pilot docs that you need to bring may be seen in the Competitor Checklist on the IAC web site in the members section.

Please make sure that your airplane has a compass card and an official weight and balance in its docs. These two items have caused pilot distress and frustration at past contests.

Free Programs - Remember, one copy that you bring will be made available for all of your friends to look at, critique, and borrow. Please double check that your Free Program uses all of the new Aresti catalog numbers and K factors and is signed off by a judge that was current at the time of signing. Photocopies of documents are permissible for IAC contest registration; however, FAA requirements may differ.

Some IAC forms are available on the IAC web site, members section, if you need to check what to bring.

For the aircraft: Airframe and engine logs; airworthiness certificate; registration certificate; operating limitations; current weight and balance data, FAA legal parachute repacked within the last 180 days; proof of insurance ($1 million minimum, see Official IAC Contest Rules.
