Noise levels for U.S. certificated and foreign aircraft

This FAA Advisory Circular (AC 36-1H) published in 2001 and updated in 2012 provides official noise level data for U.S.-certificated and foreign aircraft, including turbojet and propeller-driven planes tested under 14 CFR Part 36 and ICAO Annex 16 standards. Noise measurements, expressed in Effective Perceived Noise Levels (EPNdB), cover takeoff, sideline, and approach conditions and are organized across multiple appendices by aircraft type and compliance stage. The document serves as a reference for tracking progress in aircraft noise reduction and supports noise policy decisions at airports across the United States.

Obama’s Climate Betrayal

Elizabeth Kolbert Some international disputes are significant for symbolic reasons, others for substantive ones. The current conflict between the United States and the European Union over airline-emissions limits is both. Unfortunately this means that the U.S. is doubly on the wrong side. The Obama Administration ought to be applauding the Europeans. Instead it’s threatening a

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
