This January 2020 update from the Sea-Tac Stakeholder Advisory Round Table (StART) Noise Working Group covers three main areas: a Ground Noise Study collecting 2019 operations data from airlines, an Aircraft Departure Profiles Analysis showing that the 'distant departure' procedure reduces noise the most for nearby communities, and a Late Night Noise Limitation Program identifying EVA Air, FedEx Express, and China Airlines Cargo as the carriers with the most noise violations in Q4. The study was scheduled to produce a final report with mitigation options by October/November 2020. The update was presented at the Highline Forum on January 22, 2020.Open full document
Notes
This document is a StART Noise Working Group update presented at the Highline Forum on January 22, 2020. It covers three main topics: the Ground Noise Study (data gathering and study schedule), Aircraft Departure Profiles Analysis (comparing distant vs. close-in procedures for the 737 and upcoming Boeing 777 analysis), and the Late Night Noise Limitation Program (Q4 results showing EVA Air, FedEx Express, and China Airlines Cargo had the most noise exceedances).
