The longest runway measures 4,300 ft (1,311 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.
St Marys Municipal Airport lies at 1,934 ft elevation.
Local operations run on America/New_York. 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.
