The European Regions Airline Association (ERA) has demanded a “balanced approach” to environmental controls in the European Union transport industry following the publication of its new study on the noise performance of the continent’s regional airline fleet. The “Growing Quieter” report concluded that the noise generated by the average regional aircraft is about half what it was in the early 1970s.
Jan. 1, 2006, is the date for the implementation of the International Civil Aviation Organization’s (ICAO) Chapter 4 noise limits. The latest noise and emissions standards (European terminology uses “Chapter” to correspond with the U.S.
In what is being hailed by general aviation as a landmark decision, the FAA has ruled that the ban on Stage 2 aircraft at Naples Municipal Airport (APF), Fla., is unlawful. But the Naples Airport Authority (NAA), which operates the airfield, plans to file an appeal in federal court.
At its triennial meeting in Montreal in early October, the ICAO Assembly–which includes representatives from all 187 ICAO member nations–approved a more flexible approach to the application of aircraft noise regulations.
The Burbank, Calif., airport authority is considering using an FAA noise study to expand an overnight curfew at Burbank-Glendale-Pasadena Airport (BUR). The draft proposal is contained in an ongoing FAA Part 161 noise study typically required before an airport can implement aircraft operating restrictions. The Burbank proposal would close the airport to all operations– regardless of aircraft noise level–between 10 p.m. and 7 a.m.
Despite an agreement signed in 2006 to mitigate noise around the famous French Riviera city of Saint-Tropez, helicopter operators and local authorities are still at odds about decibels in the popular vacation locale. The acrimony stems from the fact that none of the affected parties seemed to keep its promises last summer.
Few sounds are louder than a jet aircraft at takeoff.
The decibel level of a climbing jet engine at full power can be higher (140 dB) than that of a chain saw (110 dB) or ambulance siren (120 dB), according to the National Institute for Occupational Safety and Health.
But relief may be a toggle away, if recent university research finds its way into aircraft cockpits.
Even though noise wasn’t a factor in the accident, February’s Challenger overrun at Teterboro has inevitably resurrected local residents’ complaints about aircraft noise. It doesn’t take much, as we all know, to reinvigorate the anti-noise folks.
Westchester County Airport (HPN) in White Plains, N.Y., today presented its 2005 Spirit of Noise Abatement Award to 32 of its based operators and corporate flight departments for maintaining 100-percent compliance with the Voluntary Restraint from Flying Program (between midnight and 6:30 a.m.) and for not exceeding 93 dBA on approach and departure as measured by the airport’s noise-monitoring system.
You couldn’t be in a better place than Le Bourget during airshow week to appreciate–if that’s the right word–aircraft noise. Yet a comparison between the takeoff rumble of the newest airliners and the thunderous departures of the latest military models amply demonstrates the progress in noise suppression made by the civil aircraft industry. And this progress continues, aimed at the eventual development of truly silent aircraft.
