Draft letter of agreement: Informal runway use program

This draft Letter of Agreement between the FAA and the Port of Seattle establishes a voluntary Noise Abatement Informal Runway Use Program for Seattle-Tacoma International Airport (Sea-Tac). It outlines preferred runway assignments for both South Flow and North Flow operations, with special late-night rules between midnight and 5 a.m. that reduce use of the third runway to limit noise impacts on surrounding communities. The FAA retains authority to deviate from these preferences whenever safety, weather, or operational conditions require it.
