The FAA is planning to modify helicopter routes in the District of Columbia and parts of Northern Virginia. The route modifications are based on data collected from a six-month pilot program launched by Helicopter Association International (HAI) and the Eastern Region Helicopter Council in partnership with PlaneNoise, an aviation noise consultancy.

The pilot program was initiated in response to recommendations from a 2021 report by the Government Accountability Office, which Rep. Don Beyer (D-Virginia) and other federal lawmakers representing the Washington metropolitan area had requested. The program collected flight-tracking data and correlated it with helicopter sound complaints, identifying opportunities for altitudinal and zone changes.
