Flying In?

(ONO UNICOM 122.8)

The airport will remain open throughout the weekend, and transient aircraft parking is available. Be sure to monitor UNICOM and stay aware. Note that our staff will be setting up the competition (grass) runway throughout the day on Thursday and early Friday. If the red flag is up on the trailer and/or yellow X’s on the runway, land on the asphalt instead.

If you arrive during the practice on Friday or the competition on Saturday, our airbosses will advise you of any competition traffic and may ask you to hold for a break between heats. We highly recommend you plan your arrival and departure outside of the event windows.

Advise upon landing if you are a competitor, camper, or transient spectator so that you will be parked in the appropriate area.
