Special Flight Rules Area (SFRA)

The National Capital Region is governed by a Special Flight Rules Area (SFRA) within a 30-mile radius of Ronald Reagan Washington National Airport, which restricts all flights in the greater DC area.

The SFRA is divided into a 15-mile radius inner ring and a 30-mile radius outer ring.​

• The Flight-Restricted Zone (FRZ) extends approximately 15 nautical miles (about 17 statute miles) around Ronald Reagan Washington National Airport.  The FRZ has been in effect since September 11, 2001.

• Flying an unmanned aircraft within the 15-mile radius inner ring is prohibited without specific FAA authorization.
