The County’s General Aviation Noise Ordinance (“GANO”) prohibits commercial departures between 22:00 and 07:00 (08:00 on Sundays) and commercial arrivals between 23:00 and 07:00 (08:00 on Sundays). The Airport Director or his designee may authorize a departure or arrival outside of the commercial operations hours for an emergency, mechanical, air traffic control or weather delay, which is substantially beyond the control of the air carrier. All curfew exemption requests are reviewed by JWA and must receive express approval in advance of the specific arrival or departure. The table below lists each commercial operation during curfew hours for the most recent month.
