Cheyenne Military Operations Area Modification Environmental Study

This airspace proposal will raise the flight floor in the existing Cheyenne military operations area from 300 to 500 feet above ground level, decreasing noise impacts on the ground in areas that underlie the current training airspace. Through consultation with Native American tribes, the Colorado Air National Guard has agreed to maintain a 5-nautical mile radius buffer around the center of the Sand Creek Massacre National Historical Site, Colo., with a flight floor of 5,000 feet above ground level. The training airspace is also expanding into Kansas, decreasing density of military aircraft in the military operations area.
