Butts AAF (Fort Carson) Air Field — Fort Carson, United States

FCS is Butts Army Airfield, the military airfield located at Fort Carson, near Colorado Springs, Colorado. It primarily supports U.S. Army aviation units stationed at the installation, including helicopter training, maintenance, and logistics operations tied to Fort Carson's combat brigades. The airfield's location near the Front Range of the Rocky Mountains gives units a distinctive high-altitude training environment, useful for preparing aircrews and equipment for mountainous or high-elevation deployments. As with most Army airfields, Butts is not used for public commercial air travel; it exists to serve the operational and training needs of the post, complementing the nearby Colorado Springs Airport, which handles the region's civilian passenger traffic.
