In response to community concern after FAA implemented area navigation (RNAV) flight procedures at Boston Logan International Airport (BOS), Massport has undertaken a unique study to identify opportunities to reduce noise from aircraft overflights. In September of 2016, Massport and the FAA signed a Memorandum of Understanding (MOU) in which Massport committed to select and convene a technical team to investigate the feasibility, benefits, and impacts of various procedural changes, provide outreach to communities and incorporated community feedback, and propose changes to PBN procedures to the FAA. The FAA agreed to receive these recommendations, evaluate each for safety and its impact on the efficiency of BOS and the National Airspace System (NAS), and participate in community outreach in a supportive role to Massport. HMMH is leading coordination among the various parties (Massport, MIT and the FAA) and preparing the historical and final noise modeling.
