Are there consequences for pilots who do not follow noise abatement procedures?
Pilots’ responsibilities are to follow the directions of air traffic controllers. If that requires a pilot to fly lower than usual, then that is what he/she must do. See Flight Air Traffic Control (ATC). Noise abatement measures are adhered to on a purely voluntary basis. They are, by no means, enforceable. A proactive noise office will regularly remind air traffic controllers of the policies and may monitor their compliance. In an uncontrolled environment, it is not uncommon for the airport to find out who owns the offending aircraft and send a letter to remind them of certain policies. But, again, aircraft cannot be banded () due to the undue burden it may place on interstate commerce.
