    Comparison of Researched Airports on Specific Issues of Membership, Recording, and Invited Experts

    This document compares the governance practices of three major U.S. airport advisory committees — Charlotte-Douglas (NC), LAX (CA), and Chicago O'Hare — across key issues including membership by elected officials, public recording of meetings, agenda-setting, advance notice of materials, and inclusion of expert witnesses. The comparison is used to evaluate StART (Sea-Tac Airport Roundtable), which currently lacks most of these features, with the BAC (Boeing Airport Committee) flagging items such as public recordings and expert witness inclusion as highest priorities. The findings highlight significant gaps between StART's current practices and the more transparent, publicly accessible models used at other major airports.

    Airbus A320 “Whistle”: ONCC Technical Committee Meeting, April 14, 2020

    Airbus A320 family aircraft (A318, A319, A320, A321) manufactured before 2014 produce a distinctive high-pitched whistling noise during descent, caused by airflow passing through Fuel Over Pressure Protector (FOPP) cavities located on each wing. The noise fades once the landing gear is deployed. A small device called a vortex generator, installed just in front of each vent opening, has been identified as an effective fix, reducing noise levels by up to 4 decibels during the approach phase.

    Carriers battle over airports

    Major U.S. airlines and local officials are planning approximately $100 billion in airport renovations over the next several years, with projects underway or proposed at airports including Seattle-Tacoma, Los Angeles, O'Hare, and LaGuardia. Airlines like American, United, and Delta are playing a central role in funding these upgrades — either paying directly or making long-term service commitments that back municipal bond issues. Competition between carriers over gate allocations and construction priorities has at times stalled negotiations, as seen when American Airlines challenged United's favored position in Chicago's $8.5 billion O'Hare expansion plan.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
