Aircraft noise is regulated by the FAA, not by Yellowstone County or Billings. Billings Logan International Airport (KBIL), city-owned and located in Yellowstone County atop the Rims, follows FAA-established noise-abatement procedures. Neither the county nor city sets an enforceable aircraft decibel limit.
Federal law preempts local regulation of aircraft in flight, so neither Yellowstone County nor the City of Billings sets an enforceable aircraft-noise ordinance; the FAA governs overflight noise and any noise-abatement flight procedures. Billings Logan International Airport (KBIL), owned by the City of Billings and sited two miles northwest of downtown on the Rims in Yellowstone County, publishes FAA-generated noise-abatement procedures for pilots. Ground-based noise on airport property that is not part of flight operations could still be addressed under general nuisance principles, but in-flight and takeoff/landing noise is a federal matter. The county sets no rule here.
No local aircraft-noise penalty applies; enforcement of flight noise and abatement procedures rests with the FAA.
