On December 4, 2013, Representative Joseph Crowley of a district in the Bronx and Queens, New York, heavily impacted by operations at LaGuardia Airport, introduced the “Quiet Skies Act” (H.R. 3650). Supported by a variety of Congresspersons from other similarly impacted districts, the Act requires passenger airlines to replace or retrofit 25% of their fleets every five years until 2035 to meet a “Stage 4” standard, approximately 10 decibels lower than currently approved “Stage 3” engines.
The conversion mandated by the Act might seem to result in significant relief to populations impacted by frequent overflights of Stage 3 aircraft. There are, however, at least two conditions significantly vitiating the Act’s impacts.
