Two different procedures are available for departing AirVenture, depending on weather conditions and your preferred method of flight - either VFR or IFR.
Thoroughly review the information in the Special Flight Procedures AirVenture Oshkosh NOTAM prior to beginning your journey home. Ensure that you always have a copy of the NOTAM with you, and remember, the information presented here is NOT a substitute for the official NOTAM.
Also, when KOSH is IFR, taxiing is prohibited except for aircraft with an IFR clearance.
During AirVenture, whether departing VFR or IFR, all surfaces other than the active runways are considered to be Non-Movement Areas. This doesn't mean that you cannot taxi on them; it simply means that Air Traffic is only controlling surface traffic that is on active runway.
Please be alert for taxiing aircraft in all aircraft parking areas.
