This presentation examines the consequences of runway configuration changes at Seattle-Tacoma International Airport (Sea-Tac), including louder departure noise for Burien residents, reduced airport capacity, and potential FAA workaround taxi routes. It references Seattle Air Traffic Control Tower standard operating procedures for opening and closing runways, and analyzes the feasibility of simultaneous parallel runway operations under FAA Order JO 7110.65. Key technical challenges identified include the need to relocate the Instrument Landing System, extreme ramp congestion, and the possibility of displacing the Runway 34R threshold by approximately 3,400 feet to achieve parallel threshold alignment.Open full document
Notes
A presentation examining the consequences of parallel runway operations at Seattle-Tacoma International Airport, including noise impacts on Burien residents, airport capacity constraints, and ILS relocation requirements. The slides reference FAA Order JO 7110.65, Seattle ATCT Standard Operating Procedures, and FAA regulation 5-8-5a regarding parallel runway threshold requirements, illustrating that a displaced threshold on RWY 34R of approximately 3,400 feet would be needed to achieve parallel thresholds.
