Abraham Lincoln Capital (KSPI)

Abraham Lincoln Capital is the level-4 tower serving Springfield, the Illinois state capital. Two crossing runways work the field over a prairie of general-aviation traffic: an eight-thousand-foot primary and a long crosswind runway.

Springfield mixes American Eagle regional jets and Allegiant service in over a general-aviation majority, so you are threading a few scheduled arrivals through pattern work and light singles. You work Springfield Tower. Northeast flow lands and departs the 4; southwest flow uses the 22, with the crossing runway as overflow. The fix ring gives a clean four-quadrant spread to feed from.

This is the Steady tier: a small-field rhythm with a real regional-jet feed. A calm board that still rewards a clean sequence.
