Noise abatement procedures are only effective if they are used. Noise impacted communities are frequently heard to complain that, despite the complex, time consuming and expensive process needed to develop and implement noise abatement procedures at airports, either through the FAA’s Part 150 process, or through other airport specific processes, airlines seem to ignore them. The rationale often provided is that each airline is entitled to develop and implement its own flight procedures, some, but not all of which incorporate the specified noise abatement procedures. This situation was exacerbated in 1990 when the Airport Noise and Capacity Act, 49 U.S.C. § 47521, et seq., took noise abatement policy making out of the hands of local airports and placed approval authority exclusively in the hands of the FAA.
A deceptively simple solution to this pervasive problem of airlines non-uniform observance of airport specific noise abatement policies has been developed by a small, new company in Truckee, California, Whispertrack.
