2009 Noise Contour Technical Report
The Raleigh-Durham Airport Authority (RDUAA) requested that Harris Miller Miller & Hanson Inc. (HMMH) prepare annual Day/Night Average Sound Level aircraft noise contours for the Raleigh-Durham International Airport (RDU) for calendar year 2009.
HMMH has refined the contour preparation process each year by utilizing the latest available technologies. Beginning with a small sample of flight tracks traced from the ARTS radar at the control tower, the process of flight track modeling has evolved as described in Section 2 of this report. The remainder of this section of the report describes the contour preparation process in detail.
