Helicopter operations over Cook County fall under exclusive FAA jurisdiction under 49 USC 40103, so neither the county noise ordinance nor municipal codes can directly limit helicopter altitude or routes. Complaints route to the FAA Chicago FSDO and O'Hare TRACON.
Federal Aviation Act preemption (49 USC 40103) gives the FAA sole authority over aircraft in flight, including helicopters, so Cook County Chapter 38 noise provisions cannot regulate helicopter altitude, route, or in-flight noise. The FAA Chicago Flight Standards District Office (DPA FSDO) handles low-altitude complaints, and the Chicago TRACON (C90) sequences rotorcraft inbound to O'Hare and Midway. Helicopters using public-use heliports must comply with 14 CFR Part 91 minimum safe altitudes (1,000 feet over congested areas, 500 feet elsewhere unless landing). Cook County retains limited authority over heliport siting through Chapter 102 zoning in unincorporated areas. Municipal noise ordinances cannot reach in-flight operations.
Residents cannot cite operators under county or municipal noise codes for in-flight helicopter noise; FAA preemption controls. The FAA pursues 14 CFR Part 91 enforcement for low-flight violations through the Chicago FSDO complaint portal.
