PREFLIGHT PLANNING

For one week each year, EAA AirVenture Oshkosh has the highest concentration of aircraft in the world. Your careful reading and adherence to the procedures in this Notice are essential to maintaining the safety record of this event. Flight planning should include thorough familiarity with Notice procedures, as well as knowledge of primary and alternate airports. Keep a copy of this Notice available for in-flight reference.

Planning your Alternate Airport

1. Pilots intending to land at Wittman Regional Airport (OSH) should be prepared for the possibility of diverting to an alternate airport, such as Fond du Lac (FLD), Appleton (ATW), or Green Bay (GRB). These airports have parking and scheduled transportation to Oshkosh.
2. If your alternate is Fond du Lac, check the FOND DU LAC ARRIVAL/DEPARTURE section for temporary control tower information.
3. Pilots on VFR flight plans diverting from Oshkosh are reminded to change their flight plan destination with flight service.

   OSH Flight Planning

4. Beginning Thursday, July 17, 2025, OSH is closed to all arriving aircraft from 8:00 PM until 7:00 AM CDT daily, except Thursday July 24, 2025 – no Fisk arrivals before 8:00am. Also, some or all categories of aircraft may not be accepted due to parking saturation, ground conditions, TFRs, scheduled airshows, or other activities.

   OSH Airshow Demonstration Area/TFRs

5. Check FDC NOTAMs for the Airshow Demonstration Area. TFR information will be posted at tfr.faa.gov.

   2025 Oshkosh Airshow/TFR Times (CDT)

   Monday, July 21, thru Saturday, July 26: 2:15- 6:30 PM

   NIGHT SHOW Wednesday, July 23: 8:00-10:00 PM

   NIGHT SHOW Saturday, July 26: 8:00-10:00 PM

   Sunday, July 27: 1:00- 4:30 PM

   Wittman Regional Airport will be closed via Class D NOTAMs and all aircraft must remain clear of the Airshow Demonstration Area and the TFRs when they are active.

   Check the Arrival ATIS (125.9) to determine when the airport is reopened. OSH arrivals are normally resumed 30 minutes after each afternoon airshow.

   OSH Aircraft Parking

6. Separate aircraft parking areas are used at OSH for different types of aircraft. Parking for show planes (experimental, warbird, rotorcraft, amphibian, and production aircraft manufactured prior to 1971) has generally been available throughout EAA AirVenture. Parking and camping areas for other aircraft may reach saturation at times.
7. Parking area status is available via www.eaa.org/aircraftparking. The AirVenture Arrival ATIS (125.9) also has parking availability information, when applicable.
8. Some aircraft camping and parking areas have changed for 2025 to maximize use of available space. Pilots need to follow ground marshal signals to the locations currently in use.
9. Pilots landing at OSH must use a printed sign to designate their intended parking or camping area. The sign should have large dark letters readable from at least fifty feet. It can be handmade or printed from www.eaa.org/signs (no tablet computer signs, please). Display it in the left side of your windshield after landing. Use one of the following codes:

   

10. Optional: GAC and GAP may place an additional sign with N or S to request North 40 or South
    1. 40. THESE REQUESTS ARE NOT GUARANTEED.
11. A similar sign with the letters VFR or IFR will be used when you depart.
12. Text OSHARRIVAL to 64600 for updates on the current status of AirVenture arrivals.

    VFR Route Planning Guide

13. The VFR arrival to Oshkosh starts at the ATC designated Transition to the City of Ripon, Wisconsin (Chicago sectional chart). These four graphics show sample routes that bypass high- density airports enroute to and leaving the AirVenture area. Be sure to use current charts. Use extra caution for heavy traffic.
    1. Check NOTAMs for large Military Operations Areas (MOAs) in west central Wisconsin.

    

    

    VFR Transition through Chicago Approach

14. Pilots are urged to use the VFR FLYWAY PLANNING CHART for the Chicago area.
15. Class Bravo clearances for VFR aircraft not available.
16. VFR services at or above 5500:
    1. North of ORD 125.0
    2. South of ORD 126.62
17. ORD arrivals enter Chicago airspace between 9000 and 12000 feet. VFR overflights strongly encouraged to receive flight following.
18. Aircraft transiting the shoreline MDW ATIS 132.75. If MDW landing 22L, jet traffic crosses shoreline at 3000 feet. Pilots urged to remain below MDW Class C airspace.
19. The floor of the west side Class Bravo is 4000 feet. Use caution for jet traffic level at 4000 feet.
20. Caution heavy parachute activity near 8N2 and RPJ at or below 14,500’MSL

    

    FISK VFR ARRIVAL TO OSH

    General Information

1. This procedure is to be used by all VFR aircraft landing at OSH from Thursday, July 17 at Noon CDT through Noon Monday, July 28, 2025 (except those using the Turbine/Warbird, Ultralight or NORDO arrivals). Thursday July 24, 2025 – No arrivals before 8:00am.
2. The procedure starts by using one of the ATC designated Transitions to Ripon, WI (15NM SW of OSH), requires visual navigation, and can be supplemented by VFR Waypoints. Pilots then follow a railroad
3. track from Ripon to Fisk, WI. ATC at Fisk controls traffic flow and assigns OSH landing runways and approach paths (see FISK VFR ARRIVAL TO OSH section).

Planning

4. Plan your arrival to avoid airport closure periods, such as the daily airshows (listed under PREFLIGHT PLANNING). Arrivals normally resume 30 minutes after daytime airshows. Allow ample time to arrive and park before the daily airport closure at 8 PM CDT.
5. Plan your fuel load carefully. If you do not have sufficient fuel for unexpected holding and possible landing go-arounds, divert to an alternate. If your fuel status is critical, notify ATC immediately.
6. First, fly the aircraft. If you are not comfortable with the OSH AirVenture procedures, please consider flying into FLD or ATW and taking public transportation to OSH.

Approaching Transition Starting Point

7. Ensure lights are on within 50 miles of OSH. Leave transponder on throughout approach.
8. Tune to Arrival ATIS (125.9) no later than 60 miles from OSH Airport and note arrival runways in use. Have the FISK VFR ARRIVAL TO OSH NOTICE sections available. Then monitor Fisk Approach (120.7).
9. Arrive at Transition Starting Point at 90 knots and 1,800’. For aircraft unable to operate comfortably at 90 knots:
10. Slower aircraft should use maximum cruising speed. ATC recommends arrival at Fisk 7:00-7:30 AM CDT if practicable.
11. Faster aircraft use 135 knots and 2,300’ if needed for safety of flight. Expect descent at or after Fisk.

Transitions

12. Begin the procedure at the ATC designated Transition starting point. ATC will advertise the transition starting point on the Arrival ATIS however real time changes may be made on FISK Approach Frequency. Pick out an aircraft of similar type and speed to follow. Remain at least ½ mile in-trail behind the aircraft you are following. Do not fly side by side unless you are a flight. Do not overtake another aircraft. Do not “S-turn” to follow another aircraft, instead break off the procedure and proceed to the starting point and follow another aircraft of similar speed.



Endeavor Bridge Transition

13. This Transition starts at the city of Endeavor, WI (47 miles SW of OSH) and is used during extremely high volumes of traffic. This transition has a VFR Waypoint (VPENV= 434503N/892856W) and is located over the junction of Interstate 39 and railroad tracks north of the city. Proceed from this point to the SW corner of Puckaway Lake, then the SW corner of Green Lake, then Ripon, then Fisk via the railroad tracks. There are few visual reference points on this transition between Endeavor and Puckaway Lake. A 095° track for 11 miles is a good reference.



Puckaway Lake Transition

14. This Transition starts at the SW corner of Puckaway Lake, WI (36 miles SW of OSH) and has a VFR Waypoint (VPPLK= 434425N/891329W). Proceed from this point to the SW corner of Green Lake keeping the shoreline of Puckaway Lake off your left, then to Ripon, then to Fisk via the railroad tracks. Maintaining appropriate in-trail spacing will improve the likelihood of continuing inbound on the procedure later.



Green Lake Transition

15. This Transition starts at the SW corner of Green Lake, WI (26 NM SW of OSH). This Transition has a VFR Waypoint (VPGRN = 434608N/890250W). Proceed single file from the SW corner of Green Lake to the city of Ripon (RIPON= 435017N/885040W) then Fisk, WI via the railroad tracks. Remain ½ mile in- trail of the aircraft you are following.



Ripon to Fisk

16. If holding is not in progress, proceed to the northeast corner of Ripon (OSH 232°, 15.5 DME).
17. Proceed single file, directly over the railroad tracks from Ripon northeast to Fisk (10 miles). Remain at least ½ mile in-trail behind any aircraft you are following. Do not overtake another aircraft unless authorized by ATC.
18. Do not “S-turn” to follow an aircraft; instead, break off the procedure; proceed to the starting point; and follow another aircraft of similar speed.
19. Pilots may reference Ripon and Fisk VFR Waypoints, VPRIP and VPFIS. All aircraft must visually navigate directly over the railroad tracks from Ripon to Fisk.
20. If possible, lower your landing gear prior to reaching Fisk.
21. The small town of Pickett is about 4 miles from Fisk (steam from the grain drying facility). After this point, listen very carefully for ATC instructions directed at your aircraft.



Ripon



At Fisk

22. Controllers will call your aircraft by color and type (if known). No verbal responses are required. If you do not understand the ATC instructions, or need clarification, request instructions on frequency.
23. When you are in the immediate vicinity of Fisk (less than 2 miles), ATC will issue a runway assignment, transition to the airport and appropriate Tower frequency to monitor. Do not proceed beyond Fisk or change to Tower frequency without ATC authorization.

Fisk to Oshkosh

24. Runway assignments for the airport will include either “Follow the railroad tracks northeast” or

“Reaching Fisk, turn right and follow east/west road (Fisk Ave.)”.



Railroad Track Transition

25. Continue following the railroad tracks northeast from Fisk to Oshkosh.

Fisk Avenue Transition

26. Fisk Avenue runs 090° from the town of Fisk. Do not confuse this road with Highway 44.
27. A large microwave tower is located approximately one mile east of Fisk and ¼ mile south of Fisk Avenue. Navigate close to Fisk Ave, on the south side, but remain north of the microwave tower.

Landing Approach at Oshkosh

28. A waiver has been issued reducing arrival and departure separation standards for category 1 and 2 aircraft (primarily single-engine and light twin- engine aircraft).
29. Pilots should be prepared for a combination of maneuvers that may include a short approach with descending turns, followed by touchdown at a point specified by ATC which may be almost halfway down the runway. Use extra caution to maintain a safe airspeed throughout the approach to landing.

Maintain 90 KTS until entering the pattern

Arrivals and Departures on Separate ATC Frequencies

30. Note that two separate ATC radio frequencies are used for each landing runway – departures on one frequency and arrivals on a separate frequency.
31. As a result, landing pilots may see aircraft departing from or crossing the landing runway, but not hear ATC communications with those aircraft.

Flights of Aircraft

32. Some pilots travel together to AirVenture as a “flight”. Flights approaching Ripon should, traffic volume permitting, advise Fisk ATC (120.7) of position, identifying as a “flight of number and type aircraft”.
33. Flights that choose to maintain formation less than ½ mile in-trail are responsible for their own separation between members of the flight.
34. Although flight members generally want to remain together to the airport, this may not always be feasible. Make advance reconnection plans with all flight members in the event you become separated from one another upon arrival.

Large Formation Arrivals

35. To increase efficiency and safety of traffic arriving at Wittman Regional Airport, several large groups of similar- performance aircraft have been approved to make formation arrivals. Participation in these arrivals is limited to aircraft registered in each group and requires an FAA letter of authorization.
36. These formation arrivals are scheduled for mid-morning through afternoon on Saturday, July 20, and for mid-morning through early afternoon on Sunday, July 21. Weather and other factors may change the schedule. Traffic using the Fisk VFR arrival to Oshkosh can expect delays during these large formation arrivals. See EAA website for specific times and changes to large formation arrivals.

Note – The Fisk VFR arrival will close prior to all scheduled airport closures.

Fisk Holding

37. Holding
    1. ATC controllers at Fisk will advise on 120.7 when holding is necessary.

Aircraft over Fisk will be instructed to turn due westbound, remain single file north of the lakes, and return to the ATC designated starting point to begin the procedure again. See map under Transitions.

38. At ATC discretion the VFR holds depicted below may be used:
    1. Aircraft at or beyond Ripon: Continue to Fisk and enter the Rush Lake holding pattern as depicted.
    2. Aircraft approaching Ripon on the Green Lake Transition: Watch for traffic to follow and enter the hold at Green Lake as depicted.
    3. Aircraft approaching Green Lake on the Puckaway Lake Transition: Watch for traffic to follow and enter the hold at Puckaway Lake: Counter-clockwise starting at the SW corner.
    4. Holding pattern saturation: If the Green Lake/Puckaway Lake holding patterns are observed or reported to be nearing capacity, stay clear and proceed no further. Instead, make left turns over a point on the ground and continue to hold until ATC advises you to proceed or to transition into one of the published holding patterns.
    5. Holding Altitudes/Airspeeds: Maintain 90 knots (or maximum cruise speed if below 90 knots) and 1,800’ MSL. If unable, maintain 135 knots and 2,300’ MSL.
    6. Holding pattern Saturation: If the holding patterns are observed or reported to be nearing capacity, stay clear and proceed no further. Instead, make left turns over a point on the ground and continue to hold until ATC advises you to proceed or to transition into one of the published holding patterns.
39. Clearing Holding Patterns
    1. When ATC advises aircraft to depart a specific holding pattern, those aircraft shall transition to the arrival procedure in the following manner:
    2. Rush Lake: Rejoin railroad tracks at the southeast corner of Rush Lake and proceed northeast towards Fisk.
    3. Green Lake: Upon reaching the south- east corner of Green Lake, proceed directly to Ripon and follow the railroad tracks northeast towards Fisk.
    4. Puckaway Lake: Upon reaching the SW corner of Puckaway Lake, proceed on the transition as published toward Green Lake.
    5. Others: Proceed to Transition starting point and follow the procedure towards Ripon.

    2. Departure slot reservations will be available beginning Friday, July 19 at 0600 CDT (1100 UTC) and will not be assigned more than 72 hours in advance or be allocated during the daily airshows.

    How to Obtain a Reservation

    1. STMP reservation may be obtained by using the computer interface (e-STMP). A touch-tone phone interface option is no longer available.
    2. e-STMP: Computer access is available at www.fly.faa.gov/estmp. A user guide is available on the website.
    3. The reservation system is available 24 hours a day. If you experience difficulties with the website, contact the TFM Help Desk at (609) 485-9601.
    4. If you experience difficulty making / canceling / confirming a reservation, contact the Airport Reservation Office at (540) 422-4246.
    5. Be prepared to provide your departure / destination airports, estimated UTC time of departure / arrival, UTC date, aircraft call sign and type. Upon completion of a slot reservation, you will receive a preliminary reservation number.
    6. Between 24 and 12 hours prior to your arrival/departure reservation, you must confirm your reservation and you will receive a confirmation number. If your reservation is not confirmed by 12 hours prior to your reservation time, it will be cancelled and automatically returned to the reservations system for reassignment. Reservations made within 24 hours of the arrival/departure time are automatically confirmed with a confirmation number.
    7. The slot reservation confirmation number must be included in the remarks section of your flight plan. If possible, file flight plan at least six hours prior to departure.
    8. Aircraft are required to arrive at a reservation airport or depart KOSH within +/- 15 minutes of their reservation time. If a reservation requires change or cancellation, please do so as early as possible, to release the slot for another flight.
    9. Slot reservations do not preclude possible delays if weather conditions necessitate additional traffic management initiatives.

    IFR Arrival Route Planning

    1. An IFR slot reservation confirmation number is required for IFR flights to the Oshkosh Area and Madison Area STMP airports listed in the tables above. Keep this number on board for verification by ATC.
    2. If you do not have a confirmed reservation number, do not file IFR to one of the STMP airports – file to a destination airport away from the Oshkosh area; then cancel IFR as appropriate and proceed to the Oshkosh area using the published VFR routes.
    3. File flight plans early (minimum 6 hours prior to departure, maximum 22 hours).
    4. Pilots departing from airports within 600 NM of KOSH should receive their IFR clearances before departure; to prevent excessive airborne holding, airborne IFR clearance pickup is not recommended.
    5. Canceling IFR: When the KOSH ceiling is reported at or above 4,500’ and the visibility is greater than 5 miles, all IFR arrivals except turbojet and air carrier aircraft are strongly encouraged to cancel their IFR flight plan 60 NM from Oshkosh. Piston aircraft must then execute the VFR arrival procedure from the ATC designated Transition (FISK VFR ARRIVAL TO OSH section);
    6. high- performance aircraft unable to use that procedure must use the Turbine/ Warbird arrival from Fond du Lac (TURBINE/WARBIRD ARRIVAL section).
    7. When the reported weather is less than 4,500’ ceiling or 5 miles visibility, you may retain your IFR flight plan and expect radar vectors to the active instrument runway. KOSH arrivals can expect Direct IGVEW or PRIMO for the RNAV (GPS) RWY 27 approach, or Direct WUVMO or HETUP for the RNAV (GPS) RWY 9 approach.
    8. Be extremely alert for a high volume of traffic with widely varying performance characteristics in the Oshkosh area.
    9. In VFR weather conditions, IFR arrivals at Oshkosh will be sequenced with VFR arrivals and may be asked to land on a runway dot. Review NOTICE section FISK VFR ARRIVAL TO OSH.
