St. Louis Lambert Intl (KSTL)

St. Louis Lambert International is the template field VectorHeavy was built on, and the gentlest place to learn the board. Its defining feature is a bank of three near-parallel runways running northwest-southeast over the Mississippi, with a single crosswind runway cutting across the longest of them.

Working KSTL is a steady shift. West flow lands and departs the 30s into the prevailing northwest wind; east flow is the mirror. Because the parallels all point the same way, sequencing arrivals is about spacing on final rather than untangling crossing streams. Southwest dominates the airline mix, with American, Delta and United mainline behind it, a SkyWest and Lindbergh regional feed, and the odd FedEx or UPS heavy to trigger wake separation.

This is the Steady tier: a low concurrent cap and a relaxed spawn cadence. If you have never worked a scope before, start here.
