New Haven, CT Noise Ordinances: Aircraft Noise (2026)

Section 4-63 sets maximum A-weighted takeoff noise levels for every aircraft using Tweed-New Haven Airport, measured against the FAA's Advisory Circular AC No. to midnight. The stated goal in Sec. 4-61 is to shrink the residential area exposed to noise above Ldn 65 without shifting the burden to another neighborhood or curtailing airport operations. Section 4-64 exempts government, law enforcement, fire and rescue aircraft, Civil Air Patrol search-and-rescue flights, aircraft undergoing tests to rebut a violation under Sec. 4-67, and aircraft responding to a bona fide emergency.

Section 4-65 lets a delayed airline flight land within one hour of its scheduled window and lets an aggrieved owner appeal to the airport manager for a waiver; aircraft that used the airport during the 1984 base year but exceeded the limits were phased down to zero permitted flights by 1987. Under Sec. 4-67, the airport manager may presume a violation from the aircraft's published noise rating in the advisory circular and bar it from landing, tying down, basing or taking off, though the owner can rebut that presumption with written evidence.

except for those essential to a scheduled flight (Sec. 4-69), and no fixed-wing aircraft over 160,000 pounds gross takeoff weight may land absent an inflight emergency (Sec. 4-70). The pilot is treated as the beneficial owner or lessee for violation purposes under Sec. 4-66.
