Members of the Congressional Quiet Skies Caucus, composed of Congresspersons throughout the United States whose constituents are significantly impacted by aircraft noise, have expressed deep concern, in a letter of September 23, 2020, to the Federal Aviation Administration (“FAA”) about the inadequacy of the FAA’s statutorily mandated evaluation of “alternative metrics to the current average day-night level [“DNL”] standard, such as the use of actual noise sampling and other methods, to address community airplane noise concerns.” See FAA Reauthorization Act of 2018, P.L. 115-254, §§ 173, 188 (“Report”). Caucus members catalogue a variety of insufficiencies.
