Noise Compatibility Planning (Part 150) Studies, Baltimore/Washington Int’l Thurgood Marshall Airport

HMMH has provided comprehensive airport noise-related consulting services to the Maryland Department of Transportation Maryland Aviation Administration (MDOT MAA) since 1985, including BWI Marshall’s first Noise Exposure Map (NEM) and Noise Compatibility Program (NCP) in 1989. HMMH has updated both NEMs and NCPs regularly; the most recent NEM Update was accepted by the FAA in August 2016.

This NEM Update included noise contours developed with HMMH’s RealContoursTM, using a one-year sample of radar data from MDOT MAA’s noise and operations monitoring system. The software package converted more than 150,000 individual radar traces and associated aircraft types into INM inputs, resulting in high-fidelity modeling of BWI’s fleet mix, runway use, and flight corridors.
