This June 2020 StART Aviation Noise Working Group update outlines Seattle-Tacoma International Airport's near-term action plan to reduce aircraft noise impacts on surrounding communities. Key initiatives include a voluntary Late-Night Noise Limitation Program, a revised Runway Use Program to limit third-runway use at night, and a glideslope adjustment for Runway 34R to reduce approach noise. Additional measures include ground noise analysis, a Noise Abatement Departure Profiles Study, and encouraging airlines to install vortex generators on older A320 aircraft to lessen descent noise.Open full document
