Washington County Airport's 4,000 ft of runway is shorter than most of the 63 jet-capable fields in Missouri, close to sea level, so the published runway figure is close to what an aircraft actually needs here. 8 of the 24 types we broker clear it; the runway rules out 16. The nearest city we publish corridors for is Nashville, 255 miles away.

Runway
What can operate here
Compared against the published balanced field length of every type we broker, with roughly 3% added per 1,000 ft of elevation for density altitude.
This is runway length only. Individual airports also restrict by wingspan, noise curfew, slot availability and special approach certification, and performance moves with temperature, weight and the day. Clearing the runway here means an aircraft is worth asking about — the operator confirms it, and signs for it.
