Proposed rule making: aircraft noise measurement and evaluation specifications

Journal Article · · Fed. Regist. (Wash., D.C.); (United States)
OSTI ID:7334093

The proposed rule primarily concerns test procedure amendments which would govern the specifics of conducting and reporting noise certification tests. It would neither raise nor lower the prescribed noise levels and would not require additional tests to be performed during the certification process. As a result, there would be little or no change in the noise levels of aircraft certificated to the proposed rule and there would be no anticipated change (either increasing or decreasing) in the amount of fuel used to conduct the tests or the amount of engine emissions produced during the tests. Since the proposed rule would require no additional limitations on their in-service operations or performance, no increase in fuel usage or emissions is anticipated to result from aircraft certificated to the proposed standard. The FAA proposes to make the proposals applicable to each noise certification test conducted after March 31, 1977, or 30 days after publication of the final amendment, whichever occurs later.
