Which runway do instrument approaches serve at 00U?

Is 00U a towered airport?

No — Big Horn County has no control tower. Traffic co-ordinates on a common frequency rather than with a controller, which is listed in the frequencies table on this page.

Are these 00U charts current?

They are from the FAA cycle effective 6 August 2026, which is superseded on 3 September 2026. We publish each new cycle on its effective date. They are for flight simulation and reference only — not for real-world navigation.
