St. Louis Downtown (KCPS)

St. Louis Downtown sits on the Illinois bank of the Mississippi, across the river from the Gateway Arch, a corporate and training reliever beneath the St. Louis Class B. Three runways are packed close together: a seven-thousand-foot primary, 12R/30L, the shorter 12L/30R alongside it, and a stub crosswind, 5/23, that stays visual only.

You work Downtown Tower, a satellite seat under St. Louis Approach, and the pattern never really stops. This is a general-aviation majority field: trainers going around and around, transient singles and twins, and NetJets and Flexjet corporate jets filing in over the top of them. Northwest flow lands and departs the 30s. Southeast flow is tighter, landing 12R only; 12L carries no published instrument approach, so it departs and nothing more. The cycle publishes four arrivals and four departure procedures, so the corporate stream arrives with real St. Louis structure while the rest of the board is yours to build.

This is the Busy tier with no airline in sight: a dense mix of light traffic, fractional jets and pattern work on close pavement, with the river and the downtown skyline off your western edge.
