The longest runway measures 7,600 ft (2,316 m), a heavy-class field. Representative aircraft that operate comfortably here include the Gulfstream G550, Falcon 7X, and Bombardier Global 5500. In practice this most heavy and super-midsize jets operate here without restriction.
Ennis Big Sky Airport sits at 5,423 ft above sea level. Hot-and-high conditions can meaningfully reduce takeoff performance in summer — planners should factor density altitude into payload and fuel decisions.
Local operations run on America/Denver. 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.
