NWS Oshkosh Aviation Weather Radar Support
The National Weather Service (NWS) has designed a website to provide pilots and air traffic controllers with current and forecast weather information in and around Oshkosh and AirVenture Oshkosh. The web page displays the terminal forecast for KOSH, a time series of surface wind, and probability of thunderstorms in hourly increments at Ripon, Fisk and Oshkosh, superimposed with the latest radar imagery. Further information may be obtained at the NWS booth located in the Federal Pavilion. Feel free to offer suggestions and/or feedback to the NWS.

Safe Ground Operations for Conventional Gear (Tail Wheel) Aircraft
All pilots feel a need to be vigilant regarding safety issues. They carefully inspect their aircraft during pre-flight, run up the engine(s), check the weather. They ask themselves, “Am I physically and mentally ready to fly today?” Simply stated, pilots make many critical, safety-based decisions before the wheels start to roll.  Learn more

Departure Briefing
All pilots departing on Runway 18/36 before the daily air show should have a departure briefing, available on ATIS (128.75), in the EAA AirVenture NOTAM, or in the Departure Briefing shack located east of the control tower starting at 7 a.m., at the tent in South Aircraft Parking (Row 113), or from the roving briefer circulation through the South aircraft parking in a vehicle with a Departure Briefing sign.

International Visitors
All pilots flying into (and out of) the U.S. to attend AirVenture Oshkosh must provide their aircraft and passenger information to the U.S. Customs forms via the electronic Advanced Passenger Information System (eAPIS) at least 60 minutes prior to their last non-U.S. airport departure.

There is an additional Transportation Security Administration (TSA) border crossing notification requirement for all border crossing pilots who cannot comply with NOTAM 9/2788. For general aviation pilots flying aircraft that weigh less than 100,309 pounds that generally means if your aircraft does not have a transponder or a radio you must submit a request for a TSA International Waiver at least 5 days prior to your flight.

Reminder From U.S., Canada Border Agencies

Canadian pilots flying Canadian registered amateur-built aircraft or advanced ultralight aircraft need a FAA Special Flight Authorization (SFA) to fly in the U.S. Follow the instructions on this FAA web site, then print the SFA form and keep it in your aircraft while flying in the U.S.

Canadian pilots flying any other Canadian registered experimental aircraft (Warbird, etc.) must contact the Milwaukee Flight Standards District Office (FSDO) at 414-486-2920 (fax: 414-486-2921) to obtain your SFA.

Questions? Call EAA Information Services at 920-426-4821 or e-mail: infoserve@eaa.org

International pilots filling out the electronic CBP Private Aircraft APIS forms or the electronic TSA International Waiver forms may use either the address for Wittman Regional Airport (KOSH) or EAA as your AirVenture destination address if your aircraft will be parked at Wittman during the event:

• Wittman Regional Airport, 525 W. 20th Ave., Oshkosh, WI 54902 (Phone: 920-236-4930)
• EAA, 3000 Poberezny Road, Oshkosh, WI 54902 (Phone: 920-426-6540)

When departing Wittman Regional Airport (KOSH) and headed out of the country, this is how you should enter your departure information because the Wittman airport is not a designated CBP port of entry/departure:

• For this flight, the CBP airport closest to the point of departure is Austin Straubel International Airport (KGRB) in Green Bay, Wisconsin. For this manifest, the CBP airport of departure ("Airport") should be entered as KGRB. Because the actual city of departure ("City") is Oshkosh, the “"Actual Departure Location Description" should be entered as KOSH.
