Pilots are required to follow the directions of air traffic controllers and FAA regulations. Palm Beach County initiated a Noise Compatibility Study under Federal Aviation Regulation Part 150 (14 CFR Part 150), which is a voluntary program used to address airport noise and non-compatible land uses.  Noise abatement procedures were approved by the FAA as a part of the Part 150 process and are assigned by FAA Air Traffic Control as voluntary measures, wind, weather and traffic permitting; however, there is no penalty for failing to utilize noise abatement procedures.
