Restricted area

Restricted area is airspace where flight is not wholly prohibited, but is limited because of a known hazard or special activity. The area is identified by a chart designation and number, such as R-XXXX. The controlling agency, published times, and current status determine whether aircraft may enter.

What it governs

Restricted areas can contain unusual, invisible, or dangerous activities such as artillery firing, aerial gunnery, or missile testing. When active, the area may be closed to aircraft that do not have authorization. When inactive, the controlling information and charted rules determine whether transit is allowed.

A restricted area is different from a prohibited area, which protects a location by excluding aircraft, and a warning area, which warns of hazards outside domestic territory. The chart legend and FAA publications provide the controlling interpretation.

Example

A VFR route approaches a restricted area whose published hours overlap the flight. The pilot checks the current status and controlling facility, then chooses an approved transit or alternate route. A line on an old chart does not establish current status.

Why it matters

Restricted-area activity can create a serious hazard even when the airspace appears visually clear. Pilots review current charts, notices, and status information before departure and again when conditions or timing change.

The FAA Aeronautical Information Manual and current aeronautical charts explain special use airspace. This page does not provide live activation status.
