Airport guide
Muhlenberg County Airport (KM21) is a small airport in Greenville, KY. It sits in North America.
Muhlenberg County Airport serves general aviation operators in its area.
The longest runway measures 4,999 ft (1,524 m), a light-jet-class field. Representative aircraft that operate comfortably here include the Phenom 300, Citation CJ4, and Learjet 75. In practice this limits operations to light jets, turboprops, and short-field-capable aircraft.
Muhlenberg County Airport sits near sea level at 422 ft.
Local operations run on America/Chicago. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.
