• Abstract:
  The U.S. Department of Transportation, Federal Aviation Administration, (U.S.DOT/FAA), ; along with the U.S. DOT, Research and Special Programs Administration, Volpe National ; Transportation Systems Center (RSPA/Volpe Center) conducted a helicopter noise ; measurement flight test in Champaign, Illinois, during the period July 22 through 26, ; 1991. The primary objective of the study was to obtain the field data necessary to ; examine the feasibility of a simplified helicopter-noise-certification procedure ; (screening test). Acoustic data were measured by and stored on a hand-held sound level ; meter (on-line processing) and recorded on digital tape for later off-line ; processing. A comparison of the measured on-line acoustic data with the acoustic data ; processed off-line provided the foundation necessary to evaluate the feasibility of ; the proposed screening test. In addition to acoustic measurements, meteorological ; data and helicopter tracking and performance data were also obtained.
