Butts AAF (Fort Carson) Air Field

Butts AAF (Fort Carson) Air Field (KFCS) is a medium airport in Fort Carson, CO. Pilots and dispatchers reference it by ICAO code KFCS or IATA code FCS. It sits in North America.

Butts AAF (Fort Carson) Air Field is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 4,500-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 4,500 ft (1,372 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.

Butts AAF (Fort Carson) Air Field sits at 5,838 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.

SkyAccess inventory for KFCS updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Regional fields like KFCS are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.
