Special Use Airspace

An umbrella term for areas of the National Airspace System where flight activities are confined or where limitations are imposed on aircraft not participating in those activities. Special use airspace includes prohibited areas, restricted areas, warning areas, military operations areas (MOAs), alert areas, and controlled firing areas. Each type has different rules governing pilot access and required clearances. Special use airspace is depicted on sectional charts and its details are published in the FAA Chart Supplement and NOTAMs.
