September 7, 1977. 9 pp. Testimony before the House Committee on Government Operations: Environment, Energy, and Natural Resources Subcommittee; by Henry Eschwege, Director, Community and Economic Development Div. Issue Area: Transportation Systems and Policies (2400). Contact: Comhunity and Economic Development Div. Budget Function: Commerce and Transportation: Air Transport&aion (405). Organizaticn Concerned: Dulles International Airport; Department of Transportation; Environmental Protection Agency; Federal Aviation Administration; National Aeronautics and Space Administration. Congressional Relevance: House Committee on Government Operations: Environment, Energy, and Natural Resources Sutcommittee. The Concorde supersonic aircraft is noisier than any subsonic aircraft presently in commercial service. Pqrmitting the introduction of the Concorde or any other aircri.ft type that cannct presently meet or cannot be modified to mest noise standards is counter to the thrust of the national noise abatement effort. The validity of community response surveys is questionable, and the results should not be used in the formulation of policy on the Ccncorde. Although Concorde operations accounted for less than one percent of the take-offs and landings at Dulles, they resulted in 1,387 complaints or 79% of the total noise complaints received. The greatest percentage of Concorde complaints concerned take-off. Complaints were also made about structural vibrations. Studies of low frequency noise vibrations during the Dulles test period showed that, although the vibraticns generated by the Concorde were greater than those of subsonic aircraft, they did not result in structural damage. Although the Concorde is significantly noisier than subsonic aircraft, only about 21% of existing aircraft meet nxisting noise standards. (SW)
