This 2021 presentation by aviation consultant Jim Allerdice examines 'dispersion' — the practice of intentionally varying flight paths so that aircraft noise is spread across a wider area rather than repeatedly concentrated over the same neighborhoods. It explores the tension between the FAA's preference for Performance-Based Navigation (PBN/RNAV), which promotes precise, repeatable flight paths for safety and efficiency, and the concerns of communities living under those concentrated flight corridors. The material is relevant to ongoing debates about how airports like Sea-Tac can balance operational efficiency with equitable distribution of aircraft noise impacts.
