Washington, DC Area Helicopter Noise Information Exchange Act of 2021 This bill requires the Federal Aviation Administration (FAA) to establish a mechanism to make helicopter noise complaint data accessible to the FAA and helicopter operators operating in the Washington, DC area (i.e., the area inside of a 30-mile radius of Ronald Reagan Washington National Airport). The mechanism must be based on the recommendation of the Government Accountability Office in the report published on January 7, 2021, titled Aircraft Noise: Better Information Sharing Could Improve Responses to Washington, D.C. Area Helicopter Noise Concerns . The bill also requires any helicopter operator operating in the Washington, DC area to provide helicopter noise complaint data to the FAA through such established mechanism.
